What oil pour into Al4. The principle of functioning Al4.

French PSA automaker (Peugeot Citroen Association) together with Renault, launched this 4-speed automatic transmission into the series DP0. (she is - Al4.) in 1999.

ACAP AL4 is designed for front drive and engines from 1.4 to 2 liters. There are a large number of options for drive gears and housings. Designers argue that DP0 can transmit torque to 210 nm. But the manufacturers were forced to "fasten" settings, without bringing the transmitted torque to the limit so as not to allow the owner to kill the back cover and ensure mileage to overhaul over 150-200 TCM.

Automatic Al4-DP0. It is a unique and pretty successful development of French engineers. Its design is ingenious simple and very rational: "nothing superfluous."And as a result, it has a low cost.These advantages helped to sell more than 1 million machines with the DP machine and at the same time created a headache (pleasant, perjuditable box) for automatic transmission masters.

Although the manufacturer "Peugeot Citroen" calls her " Al4.", in Russia it knows how DP0. By classification Renault.whose cars were the first to come to the overhaul automatic transmission.

In 2013, on the basis of DP0, the French for Russia, new modifications of AL4 adaptive automatic transmission were issued for Russia (with the Tiptronic System Porsche system), which has not changed hard. Renault calls these two modifications: DP2. - for front-wheel drive cars and DP8. - for all-wheel drive. They updated an electrician, the operation of the hydrotransformer was changed, which is already turned on at first speed, and at the same time, the ZF has already made, it serves relatively long and reliably. Remkomplekt DP0 consumables are suitable for DP8. Almost completely, while only there is no new seal for the right half.

It is believed that the AL4 transmission itself is easily running to 200 tkm, and with normal operation and timely maintenance / overhaul and up to a million.

Cooling automatic transmission

DP0 has a heat exchanger for cooling oil. All heat exchanger transmissions work in temperature mode Close to critical. In the summer of automatic transmission DP0.regularly overheats, the electrician suffers, namely the hydraulicock. Such. constructive feature Many automatic transmission with heat exchanger. The duty after runs for 80-100 TCM lies on the owner.

It should be borne in mind that at the operating temperature +75 .. + 90 ° DP0 is almost eternal. The more load it on low and too high temperatures, the better the premature old age of elements is coming. In addition, the programmers allowed the gas-dried in the floor in the floor with the 2nd speed to include the mode of forced locking the coupling, which reduces the heating, but accelerates the pollution of oil and wear.

Frictions pollute the oil, dirt settles in the heat exchanger, (which also works as a filter) and as a result, after critical pollution of the heat exchanger, the oil in the heat does not have time to cool. Why hydrophlitis (and solenoids) cease to work normally. And than dirty oil, the higher working temperature And the worse controls the switches of hydroblock speeds.

The heat exchanger is not accepted due to its too high price and short reserve on the resource. It is washed with large quantities of cheap ATF oil (internal) and antimes - an outer contour. But it is easier and more efficient to embed additional cooling instead of the tired heat exchanger slaughtered by resins. Most masters prefer to install the radiator along with.

Developed -Adapters for the installation of the radiatorleft 144998 instead heat exchanger DP0. An external ATF cooling and thermostat 100099 are already connected to the adapter.

With overhaul, the age automatic transmission masters usually change the heat exchanger to the outer radiator. But all these troubles are justified if the owner plans to exploit its car for another 2-3 summer.

Replacing oil and filter

The resource of this automatic transmission to the overhaul with a neat and correct operation can be 150-200 tkm, and after timely repairs with full bulkhead and replacement of consumables can be extended to half a million if the machine itself is still on the go.

At the same time, the overhaul should be decided, without waiting when the car refuses to go and request a "dying pit."

Details for bulkhead and overhaul

Choose repair kits - press the left key.

For the complete bulkhead of the age car usually ordered all sets of consumables (components of the workshop), a set of pistons, sleeves, brake ribbon, filter and EPC \\ TCC solenoids.

Kits (Repkkomplekt "Overol") - №144002 - suitable for all French cars. The two most popular configuration masters are more complete and popular (- 144002a -pr) andmore budget - - 144002D). Both of these overol contain the gasket of the hydroblock.

Remkomplekt DP0 fitsfor DP8 / DP2. Almost completely, so far only in them there is no groove of the right half.

Repair kits for full bulkhead boxes are ordered almost always together with a complete set of friction discs - No. 144005 - friction, equally ordered non-original and original from the company. The ratio of price \\ quality is equivalent. Also suitable for DP8 \\ DP2.

A set of rubber pistons enters almost every order to overheated box overheated. The masters decided on the choice of quality and configuration (with the piston of servo) of this kit - №144008B-NK. ()

Since 2004, the hydraulicock has changed and put the hydraulic block laying (enters the Overolkit of the SCT and the presskin), the old masters are rarely changed, sometimes not even knowing that it is. Together with it, Teflon rings with 3D cut are required for the E1 package.

Full Remkomplekt Masterkit - 144007 includes a set of gaskets (002) and friction (005).

The bulkhead is necessarily made with the repair of the hydrotransformer -144001 .

Weak spots ACP AL4-DP0 by electrical part: Solenoid ( ) - Pressure electric motor 144431 . Replace leader. Plastic sealing rings are always changing with them (144179) and the sleeve - the reason for the rapid production of solenoid resources. According to the manufacturer, the solenoids of release until the fall of 2003 have constructive flaws and are required for replacement at the first automatic transmission. After replacement requires an automatic transmission adaptation. Both solenoids are usually changed (EPC linear pressure and TCC-locking of the hydrotransformer). There are "original" solenoids and solenoids Borg Warner. In the boxes with the "original" solenoids have long been already put by the solenoids of the American manufacturer of the original Borg Vorner, refusing their own production of these complex electroclapanes. But the price of the "original" is usually slightly higher. EPC solenoid resources are relatively small, especially if the knots of the box (Teflon rings and sleeves) are worn. The first EPC solenoid is common, but the unauthorized work of the second solenoid (TCC) is very quickly overheating and pollutes the oil, killing the hydraulicock. If you do not replace the sleeves and teflon rings, then the replaced solenoids live long. The remaining 6 solenoid-encryption EVS -№144421 Work without overloads and change them infrequently.
Sleeve. Cylindrical sliding bearings (so theorists call ordinary bushings) The role of seals are also performed here. And the first to popularity is the wear of the sleeves. The border wear leads to a chain reaction: they begin to skip oil, there are not enough pressure in packages and the computer makes the ERS solenoid open the channel for a complete section, the pump operates at the maximum load and the ERS solenoid begins to be accelerated. Working with the lack of pressure "kills" the frictions of the appropriate package and oil. When bulkheads check the state of the sleeves, and when the solenoid is replaced, the most stressful sleeves are checked (- 0.100 mm): Pump cover sleeve, DP0 / AL-4 (57.2X 54,8mm x13,7mm), usually order Sonnaks bushings144034 , - Pump rear stator stator bushing (29x 26.0 mmx16) -# 144037 and the sleeve of the drum E2 / E1 (37.9x 35.2 mm x17) 144036. If the wear exceeds the tolerance of all 3rd bushings, then the sleeves change the sleeve with all 144030. The Masters specializing in the DP0-AL4 have a special tool \\ "caliber" to check the wear of all 3 sleeves. After installing Sonnaksov's sleeves, DP0 walks for several more years when compliance with the purity and temperature of the oil. At the same time make sure pilotransformer overhaul - 144001 .
From loss of oil through worn joints drops pressure in the line and surround and burn friction. Depreciation of unilateral friction disks occurs evenly and friction discs change in almost all overhauls complete set: № 144005. When selling friction discs separately, the cost of the entire set is obtained above. More often buy a set Borgvorner, in 30% of cases - neoriginal. DP0, which has worked for several hours with burner butter, requires replacement of frictional friction (+ torque converter friction agent + brake tape) regulatory work Together with the replacement of the pair of solenoids. This is especially important if the friction linings are impregnated with ground oil resins, after which they significantly reduce their abilities to remove heat and keep the load until the "breakdown to slip", which leads to shocks and slippages.
When repairing superheated automatic transmission, all rubberized pistons change with a complete set, despite their condition- Piston set (7 pcs) -144008 . Basically - Taiwanese neoriginal of verified quality 144008B-NK. You can not change all the pistons if you have a great experience of defecting and replacing the pistons in this transmission. Pistons 144902 (servo F1) and 144912 (servo F2) are the first to produce a resource. Without their replacement, brake tapes clinches and burn already in the first weeks of operation after the overhaul.
- Brake ribbons (pair F2 and F3) - # 144020,which change at each overhaul of the automaton who came with burnt oil. With them together change and pistons servo (above). Brake ribbons are mostly taken non-original. But every tenth order is the original from Borg Vorner, ordered mostly novice masters and owners for the safety net. Long-term riding with a worn tape and servant leads to the fact that it is necessary to change and the extension drum package F3 - №144550.
Hydraulic valve block (hydroblock) # 144740 - the usual repair place. It categorically does not like overheating and dirty oil. From overheating, the metal plate changes geometry, spools climb and the springs are overloaded up to breakage. One of the old-age substitutions is the oil pressure sensor: No. 144415. With the local repair of the hydraulic block on the age-related car, the laying of the hydraulic lid changes - 144301. There were several modifications of hydroblocks under different engines and cars. Due to overheating, the aluminum alloy of many hydroblocks is corrosive. Often, the stove channels are clogged with a chips and a slust from the friction paper, which leads to abnormal operation of the hydroplate. With overhaul, it is necessary to check the geometry of the case. The valve blocks of releases of 2008-11 often dismissed the bolts of fastening the upper plate. The resource of the hydroblock is significantly reduced during operation with dirty oil. Silence of friction dust is abrase of channels and valve spools. The American Sonnax Repair Guru released Repair Kit for "Aorto-Coronary Shunting" of Worn DP0 Hydroplits, but rarely who are solved on such a complex operation when the new plate is not much more expensive and gives a guaranteed result. Although the hydraulicock is so reliable and maintained that rarely when the overhaul requires replacing the valve plate itself. In most cases, the cleaning and replacement of EPC \\ TCC solenoids is sufficient.
Teflon rings of the back cover of the wizard are recommended to change with each disassembly:- Compression Ring Small (32x1.9x28) and Ring compression large back cover, 2 pcs. (54x1.9x50) # 144179. (included in Remkomplekt 144002). The gasket is always replaced at local rear cover repairs - 144304 . Rings set - 144199. Worn due to operation with dirty oil, aggressive acceleration or long slip in snow or dirt. (Worn GDT coupling) leads to loss of oil pressure and clutch and friction combustion.
- One of the frequent diseases of "iron" - Needle bearing - №144231. It is between hub 570 and a 554 drum in E2 package. Each time the dp0-Al4 bulkhead is the wizard, it is recommended to check this place.
The leader in replacement among the glands and seals is the broken cuff (seal) of the pump 144070. ( pass in Remkomplekt. 144002 ) But almost always change the rest of the glands: - Semi-axes left # 144076, and outdoor right from the corps side. # 144077 Changing these seals experienced masters always happens, whether Overoll Keith was bought (Remkomplekt gaskets and seals) or not. It is worth keeping in mind that oil leakage is not treated alone alone only. This is a symptom of a more serious problem and if you do not check the wear of the bushings and work underwater transformer, The cheap replacement of the gland usually simply kills the pump, bushings and the rest of the "iron" transmission.
If the problem with the underlying sunel in the pump and sleeves is launched, then you have to change the entire pump - 144500. Almost always for repair is used by the pump.
Next - Rare Replacements of "Iron" on the corrugated age-related machines: Planetary series, rear - REAR, №144582 . Coupling drum F3 - 144550.

Inter-cruise gaskets have two types: on a car with an engine of 1.4-1.6 liters and from 1.8-2.0 liters. They differ in size (10 mm long)144305

From consumables leader in replacement is the clutch package E2 (4th).

Friction discs package E2., DP0 / AL-4, unilateral with inner teeth (№144100BI)and adjacent to it - one-sided with outdoor tooth (№144120BE. ) Change every time repairs.

Also often burn 144106 144126 package F1. And frictions with disks 144110 144130 package E1. With the replacement of frictional, the corresponding sleeves and rings are changed.

Differential - 144716. (Different on the slots on the shaft for Peugeot and Renault)

The box is very simple and maintainable. Spare parts are easily accessible on the first call. It was trained and hundreds of beginner inspection masters of automatic transmission. And if the repair is competent, then it passes not yet one summer. No wonder it was again chosen for a wide range of 21st century not only Renault-Citroen-Peugeot themselves, but even Nissan Mexican assembly, famous for their own budget and reliable janking 4-stroops for every taste.

(Automatic transmission)

ATTENTION : Drain from automatic transmission must be performed with hot oil (at least 60 ° C) to remove dirt in suspension oil.

To replace the oil in the automatic transmission, you will need an overpack, a car lift or pit, to remove the crankcase protection and unscrewing the drain plug, it is not required on some models, it is not necessary for special holes and removal it may not be required, but the drain plug may not be required. Unscrew it in any case.

1. The main plug for level check
2. Cork, oil plum tube

The volume of the fluid fused in the automatic transmission is approximately 3 liters.

To unscrew the main traffic jam on automatic transmission (in photo №1)it will take a knob or a square with a square cross section as shown in the photo.

The next step is to replace, you need to unscrew the tube - the tube for the main plum of three liters, it is unscrewed by a hex manner for eight.

NOTE : Replacement is partially produced, it is impossible to completely drain the oil from the torque converter.

When all oil glass, set:

• Cork plug and oil filling (2); Tighten the moment 0.9 ± 0.1 days
• Level check plug (1); Tighten the moment 3.3 ± 0.5 days

NOTE : The volume of the fusion of the working fluid in the automatic transmission should be approximately 3 liters.

Installing the Carter protection is not hurry, as it is necessary to control the oil level in the automatic transmission after the bay.

ATTENTION : Allowed to use only ESSO LT 71141 oil.

Filling capacity dry automatic transmission: 5.85 liters.

Volume of working fluid for fill: approximately 3 liters.

• Spin bay cork on automatic transmission (3) (preferably with a new gasket); Tighten the moment 2.4 ± 0.3 days.
• Reset the working fluid wear counter (follow the procedure specified in the diagnostic computer).

Checking the oil level in (Automatic transmission)

Prerequisites:

• Auto must be on the horizontal plane
• Absent emergency mode Automatic
• Unscrew the tube of the bay of the working fluid (3) photo
• Pour floor-liter oil
• Press the brake and switch the ACP selector several times
• Set the selector to parking
• With the engine running on idling unscrew the plug (1)
• Heat the car and automatic transmission 60 ° C (+ 8 ° C; -2 ° C)
• Wait for working fluid will not flow with air bubbles

NOTE : The oil level in the automatic transmission is achieved by draining the oil on the engine running, first the trickle, then the jet with air bubbles, then drops, usually twist the tube when the working fluid merges with air bubbles

Increased fluid level can cause oil overheating and automatic transmission

Low level, the friction rates will wear

Do not pour any washing fluids In the automatic transmission Al4!

A few more general words about replacing oil in automatic transmission
For each car owner, an integral process is to replace the oil in the gearbox. Such an action must be performed regularly and exclusively by professionals. Attempts self-decide This issue can significantly harm the gearbox functionality. To date, there are only two main types of oil replacement: partial and complete.

The process of partial replacement of oil in automatic transmission

After the arrival of the car for a hundred, the old liquid from the transmission pallet merges. After this action, the pallet is removed and the filter part. These components are subjected to detailed car wash and cleaning. After completion, they are installed back in place. It should be noted that you need to update the pallet laying and filter. Then the new oil is poured, and the workers of the service station are exposed to the desired level. The car is settled, and tosses to the lower level begins. A small minus of such a way is that the old and new option is mixed. All sediments from the working fluid remain inside the aggregate. That is why it is possible and not to notice any special changes in the operation of the automatic transmission.

Full replacement of fluid in automatic transmission

Under the action of full update, impress the exhaust oil from the aggregate. But its full of it is 100% cannot be called. The thing is that some remains. On average, it is about 0.5-1% of the total volume. Each transmission includes a cooling system in its structure. She goes beyond the box. It takes continuous circulation of fluid when the car engine is in working condition. Only modern equipment It is capable of solving the problem of removing the exhaust material from the system. But the same device takes part in pumping the new fluid.

He takes the old and immediately fills the chain of a new one. Control of the operation of the equipment is carried out by a service station specialist who monitors dashboard. The device must consist of two transparent tubes. They are intended for pumping and allow you to visually assess the overall condition of the driving oil. And only after. As the color in both tubes will become the same, the process can be considered completed. If you use a complete replacement, and not partial, then the driver gets:

• Improved automatic transmission
• Economic savings (with partly, replacement should be carried out every 10-20 thousand km.)
• Save personal time
• Box functionality pulling

Replacing oil in automatic transmission should be carried out exclusively by professionals.

Causes of oil leakage from automatic transmission

Auto Masters soviet era They joked that if the car does not eat oil, it means that it ended there. Now the situation has changed, the configuration of cars is constantly complicated. It was even important that it was exactly what kind of oil you are pouring in the box, but about his absence, no one speaks even a joke, understanding what it can lead to.

Of course, if in the morning in the morning of your car, you found a suspicious oil stain, this is not a reason to immediately call the tow truck and drive the car to the service. But check out your suspicions. To do this, on the evening, put the car into the garage, pre-laying under the automatic transmission several sheets of paper or newspapers, on which there will be a clearly visible droplets of the oil. No garage? Not a problem. Just try to choose a clean dry place with a solid coating and without strangers. In the morning we will look at the result. If there are stains of oil, the case is in the gearbox of your car. It cannot be left without attention, especially since the oil is at resting the oil has a greater viscosity. If it drips on a cold box, then while driving, when the oil begins to heat up, its turnover increases, and flow is enhanced.

Where simple

First you just remember whether any work has been done with your box lately. After all, the working fluid can be reduced due to the usual slide of the one who produced them. The reasons may be the following manifestations:

• drain oil plug is not tightened, which is not a rare phenomenon;
• not twisted to the end sensor rear stroke After replacing it, even worse, if it is not twisted on the thread;
• creation or loosely inserted probe, which measure the level in the box;
• banal overflow liquid in the box.

There is an erroneous opinion that the box does not spoil the butter. This is not true. With an excess, it will be squeezed. At the same time, the oil seals may be damaged. All this can be very easy to solve with tools and their hands. We heat the car on the pit or the overpass to be able to free access to this unit. The most important thing is to do everything without fanatism, so as not to thwart the thread on the drain traffic.

A little harder if the oil leaks through the gasket. Also, it is also possible to easily at a hundred. You just need to buy a new gasket. When replacing the place of its installation is checked for scratches or chips. If they are presented, the surfaces of the surface restore the usual epoxy resin and set the gasket to a special sealant.

Breather

When the car moves, the oil is heated when it is worth it. To compensate for the pressure drops resulting from this, such tubes are installed on the caps of the gearboxes, through which the gas during its expansion is fluent in the atmosphere. If this tube is clogged, then the pressure begins to rise inside the box, and the oil begins to pushed through the glands.

The problem of simple cleaning of the Sapuna is solved. To do this, we immediately buy a new gasket under the lid. It is not recommended to use old. Remove this cover and wire or steel cable of the corresponding diameter clean the Sapun. After that, to remove the remnants of the contamination, blow it and rinse with gasoline. On some models, the PPC Sapun is an oiled valve. It is inexpensive, so it is more expedient to replace it.

Stuffing box

For various reasons, including if you do not clean the Sapun, and simply due to wear, the oil can flow through the glands. If all is a matter of the age of the gland, then just change it and go. If the gland fails on a relatively new car, then it is worth finding out the reason for this phenomenon. It is possible that recently you used low-quality oil.

Replace the glands without sufficient skills for this, it is better not to produce on their own. It can be damaged during installation or put with a breakdown. In any case, as a result of this repair, the oil can flow even stronger.

The most unpleasant in the automatic

If the oil flows through the seal on the drive, you can only remove the cause of the transmission. Usually in such cases, car owners are at the same time trying to immediately replace the clutch, make the full diagnosis of all working mechanisms of the box and, of course, replace the gasket.

If oil drips or flows between the engine and the box, then on imported cars This may mean a damage of the torque converter. Accordingly, it is necessary to have the nearest repairs, especially this defect is characteristic of the Japanese assembly.

In any case, it is impossible to obnimally watch how the oil leaves the automatic transmission of your car, it can lead not only to expensive repair, but also to create an emergency situation, especially if the box is broken during the car movement.

How to check the oil level in the automatic transmission - tips and recommendations
How to change the oil in the engine with your own hands All about the variator on Peugeot Automobile Peugeot, Device Box Machine Al4

If you regularly carry out the necessary engineering works, It is possible to significantly increase the life of any aggregate. This statement is especially correct to the automatic transmission of AL-4. It is this transmission that is installed in Peugeot 308. Most problems appear due to the lack of competent technical prophylaxis.

Replacing the oil in the automatic transmission of Peugeot 308 do it yourself

If you believe the manufacturers, oil in the gearbox can not be replaced for 100 thousand km, there is also a sequet, according to which the owner can replace the oil with a smaller car run if it has such a desire. In practice, it is not necessary to wait for a hundred thousand mileage, if you want to do without repair automatic transmission. Specialists argue that changing the transmission oil follows after 30 thousand km. Change the transmission oil is completely, or partially. It should be noted that full procedure Every time it is absolutely optional. So that the automatic transmission worked correctly, it is quite enough to periodically partially replace the oil.

What oil to fill in AL4 automatic transmission?

What transmission fluid to use, Esil required replacing oil in the automatic transmission of Peugeot 308? It should be remembered that lubrication fluid for automatic and for mechanical boxes - These are completely different products. Special lubricants are created for automatic transmission, which are also called transmission fluids, or ATF. Thanks to them, the motorist receives many advantages:

• stabilizes the operation of the hydrotransformer;
• it is closed superfluous heat that interferes with the operation of gears (if more precisely - friction elements) in the hydrotransformer;
• malicious products are eliminated due to wear details;
• permanent lubrication of interacting elements of the unit is ensured;
• proper functioning of the control system is ensured.

For automatic transmissions, three types of oils can be used: synthetic, mineral or semi-synthetic. These oils have a different chemical composition and sets of so-called additives.

The composition of transmission oil additives affects the following characteristics:

• lubrication of interacting (rubbed) elements;
• foaming level;
• resistance to oxidation processes;
• the ability to neutralize products of wear;
• the level of aggressive impact on rubber parts;
• inflammation temperature.

For the gearbox AL-4 best option There will be a transmission oil ATF LT 71141..

Peugeot 308 replacement of oil in automatic transmission - what is needed for this

To start the procedure, it is necessary that the machine is in a raised position. Some car enthusiasts prefer to use the lift, others - the overpass, quite a few drivers consider optimal option watching pit. Also, the motorist must prepare the toolkit listed below and some materials:

• Funnel having an elongated nose. It is easy to purchase in the store, or make yourself. Just wear on a standard funnel, a tube with the desired diameter.
• You should have a set of dynamometric (or other) keys.
• The container in which the waste fluid will be poured.
• New oil.
• Clean cloth (rag, rag).

For the correct functioning of the transmission of Peugeot 308 requires approximately 7 liters. transmission fluid. It is merged, as a rule, about three liters. Change the transmission oil is not fully recommended. It is best to produce a partial replacement - enough three liters that need to be poured every 30 thousand km. If the car enthusiast decided to fully replace, he will need nine liters of a new liquid.

Main steps

1. Before starting the main actions, heating the car. For this we ride ten minutes.
2. Remove the plastic protective elements of the bumper, the same applies to the carder.
3. Under the car we are looking for a plug closing. It is easy, there are four-gamped excavations on the traffic jam, especially for the key.
4. We install under the hole through which the drain will be made prepared in advance to the container in which the waste fluid will be drained.
5. After that, we unscrew the cork on the plum and allow the old lubricant to fully remove.
6. When the flow stopped (only drops remained), we unscrew the cork inside, pour the remaining liquid.
7. We replace gaskets on traffic jams, tighten the drain hole. It should be spinning carefully so that the gasket is not damaged.
8. Shooting the cork, raise the hood and continue the replacement process.
9. We dismantle the air filter.
10. Reaching the battery, turn off plus; the block in which the fuse is located, we take to the side (this unit is placed on the battery itself). Remove the casing (for this you need to pull the part for yourself) the battery.
11. Then disconnect the "minus" terminal on the battery.
12. Using the key (size - 10) dismantle rechargeable battery (after removing the bolts).
13. It may interfere with the mass of the mass, in this case we remove the battery pack. To do this, you will have to tinker with the appropriate bolt, which is located below the fence.

1. Using the key, unscrew the plug hiding the plug hole and, accordingly, fill the gear oil.
2. Before filling a new liquid, check if existing drain plugs are closed.
3. Using a special funnel pour a new ATF. Then we close the plug hole, while we use the force of about 3.2 n / m.
4. It is also necessary to replace the gasket (which is copper) is to do it regularly, when replacing fluid.
5. By turning the plug, return the filter and the battery to the place.
6. Now you can start the engine.
7. Let the engine operates at idle until the temperature of about 60 degrees is reached, then the fan must earn a fan responsible for cooling the radiator.
8. Then we translate the selector to all possible positions, and return the lever into the "P" state.
9. By producing a replacement, a meter should be reset, tracking aging of transmission oil.
10. Having finished with the bay of the transmission fluid, it is necessary to unscrew the plug on the drain hole so that the excess lubrication fluid flows. We wait until the jet of the oily liquid starts to drip. After that, we close the plug hole.

How to check the oil level in the automatic transmission?

To correctly check the level of transmission fluid, the machine must be in the correct horizontal position. Checking the level, the motorist must pour about half a liter of fluid. Then we start the engine, wait when the fan earns. We unscrew the plum covering the plug, and allow an extra lubricant to pour out. Sometimes the oil is not poured, but just sometimes dripping. In this case, we fill the next floor of the liter of fluid, and repeat the above process. For a better understanding of the processes described above, read peugeot 308 Oil Replacement in ACP Video.

Part 1

Part 2

Many French automakers moved to the use of the percentage of machines equipped with automatic transmission, in the European market - more than 50. And this touched even the vehicle of the budget class. Now the AL4 automatic transmission is installed on these cars. What is this transmission, what is the features of its operation and problems? All of this - further in our article.

Characteristic

Al4 automatic transmission can be found on such cars as "Peugeot", "Citroen" and "Renault".

This transmission is a four-step "automatic". Initially, it was labeled as DP0. Al4 automatic transmission is constantly upgraded and now you can meet such modifications as 4HP and BVA. All of them were installed on budget cars, such as "Peugeot" 206-407 series, "Citroen", starting with "C-2" and ending with the "C-5" model. She also equipped with "Renault Scenic". Significant modernization of the box has undergone in 2004. During operation, she received many contradictory reviews of motorists. Some say that the repair is reduced to the replacement of oil, others have large problems with solenoids and valves, the replacement of which causes many difficulties and cash costs.

Operating Rules

Each car owner tries to care for his car.

And if everything is extremely clear with the engine (this is a regular replacement of oil and filters), what to do with AL4 automatic transmission? Oil here too need to change. But the rules of operation are not reduced only to the replacement of consumables.

Warming

As well as the engine, the hydroblock automatic transmission Al4 needs heating. In the electronic system, this function is provided. However, experienced motorists are advised to further warm this transmission. Regardless of temperature and weather conditions, the checkpoint must be warmed at least 5 minutes. At the same time, it is not necessary to keep the lever in the parking position. At the beginning of the move, it is necessary to avoid aggressive driving and sharp accelerations. Do not hold the box often in sports mode.

About butter

The French manufacturers say that the AL4 automatic transmission is the maintenance-free box, and the oil replacement period is not regulated. However, this is not so. This lubricant is used other than in

The fact is that the MCPP contains a crankcase filled with oil. The box is filled with half. When moving gears, the transmission rotates, they need lubricant. Thus, they, as it were, "wetted" in the crankcase and already then come into contact with the working part of other teeth. The oil is not overheated here, although also performs the heat sink function. As for automatic transmissions, this liquid is "working". It is it that performs the function of adhesion and transmission torque from the engine on the wheels. Friction discs are used on the mechanical. The "automaton" is based on a hydrotransformer, or the so-called "bagel". There are impeller inside it - small turbines. When rotating, they are connected between themselves and due to oil transmit power to the engine. Thus, the lubricant temperature here is colossal. Oil is experiencing heavy loads. Therefore, in contrast to the "mechanics", the AL4 automatic transmission requires a regular replacement of lubrication. Motorists say that it should be changed every 40 thousand kilometers. If you buy a used car and doubt the regularity of automatic transmission, it is recommended to wash the mechanism. The volume of oil for this operation is about 15 liters (by several cycles). 4 liters are poured into the box itself. As a rule, testing is always black, and on the crankcase there are traces of production - small metal chips. Than it is less, the better. It is also necessary to change the filter. Below we will talk about the problems that occur during the operation of such cars.

Emergency mode and error P1167

This is one of the most common mistakes with the Al4 box.

The main symptoms are characteristic strikes in the automatic transmission at the beginning of the movement. The transmission rises into the emergency mode and includes the third gear. In the instrument panel, Gearbox faulty error occurs. It usually disappears when the ignition is turned off and turned on. However, the box when moving does not stop "kicking". The reason for this is the low pressure of the AL4 automatic transmission. It may differ from a given computer for 1-1.5 bar. Perhaps it is caused by a low level of oil in the transmission. It occurs when leaks due to weakened hydroblock mounting.

How to eliminate?

If such symptoms occur, you need to check the box for leaks. If the car mileage is more than two hundred thousand, it is necessary to inspect the condition of the heat exchanger. Also on old cars, the oil pressure spread occurs with a faulty or contaminated hydraulicone. Solution - disassembly and flushing an item. After that, errors are reset and the new transmission oil is poured.

It is worth noting that for automatic transmission it has another viscosity. It is impossible to pour into it a lubricant intended for "mechanics". If traces of testing and contamination were detected, after 1 thousand kilometers, it is necessary to replace the oil and re-check the level of its pressure in the hydraulic unit.

It is impossible to translate the CAT selector from the position "P"

If the box lever is not translated from the "Parking" mode when you click on the brake pedal, and when you are released - the "Drive" mode is activated and the error is most likely. It is associated with brake system. You must scan the car for errors. There is a problem with ABS and ESP. The reason for the breakdown is a bad contact or breaking the brake pedal switch wiring circuit. Also may be faulty "confusion". Solution - replacement of the element either wiring a switch (if there is a bad contact problem).

Error P0730.

She talks about slipping clutch. It may occur both in a warm box and "on the cold".

Symptoms - Picks and transition to emergency mode. Sometimes when moving, the engine turnover is floating (the accelerator pedal is in the same condition). This is the effect of towing clutch. In this case, fails solenoid valve ACP AL4. It is also possible to break the hydroblock itself. Further movement on such a car is prohibited, since there is a risk of breaking the bagel belt brake. Such a malfunction occurs usually on old cars and is solved by replacing the valve and the hydrogenation stretch. As in the previous cases, at the end of the repair, a new oil is poured into the transmission and the AL4 automatic transmission sensors are checked for the scale of oil pressure scatter.

How not to overlay?

It is important not only to warm this box, but also not to use it at high temperatures. What is required for this? If you are standing in a traffic jam for more than 30 seconds, do not be lazy to translate the lever from the "Drive" position in the Neutral. Do not hold the leg on the brake for a long time, since the box malfunctions may occur with this system.

About the sensor

When operating cars with the Al4 box, problems arise with the oil pressure sensor. His factory error is 0.001 bar. This means that with the slightest fatigue of the sensor, it begins to "lie" and displays an error on the control unit. Because of this, the box begins to work badly. If you detect a malfunction in time, you can put in a relatively small price - $ 100. This is the cost of a new oil pressure sensor. Further operation of the car with a faulty element is prohibited, as this may lead to problems with the solenoid.

Brake ribbon fault

With frequent jumps of oil pressure (which can be caused by the sensor breakdown), there is a breakdown. Many motorists come to the conclusion that it is cheaper to order a spare part "On Disassembling". However, most Al4 transmissions that are "on the analysis" are far from perfect condition. Almost all of them have exhausted their resource. We also note that this box is constantly modified. The type of pressure regulator, software changed. By the way, according to the first models of this box was poor quality, because of what she often knocked out a mistake.

Solution - Restressing Software, replacement for newer. But there is one trait. After 2004, the box was significantly modified, and when reprogramming, you need to take into account the year of release of your car.

Follow the oil level

For insufficient level There are scattering in pressure. As a result, the emergence of one of the previous errors. Once every 10,000 kilometers it is necessary to check the oil residue inside the transmission. Each box has a dipstice with MAX and MIN marks, and on the back - notes and Cold. It is necessary to check on the heated transmission. 10 kilometers enough to return it to normal operating mode. When checking the car should not be under the tilt. It can also be swirling - the probe is removed on the operating engine, when the "P" selector is positioned. If the level is insufficient, you need to return it to the maximum mark. You can not mix transmission oils. therefore better decision There will be a complete replacement of oil. It is expensive, but so you will protect yourself from other breakdowns.

Finally

Thus, the rules of operation of this transmission are reduced to a regular replacement of oil and pre-warming elements before starting the car movement. If any errors occur, or if the box got into emergency mode (third transmission), it is not recommended to continue moving by its move. Also you can not overheat the oil. This will not be better reflected in the electronics. Normal oil temperature inside automatic box AL4 is 75-90 degrees Celsius. If you follow all rules of operation, the resource of this transmission will be more than 300 thousand kilometers. However, if you ignore the heating and new oil, the replacement of the AL4 automatic transmission will be inevitable.

So, we found out what a given box features, how to operate it correctly and repair in the event of a breakdown.

During the operation of the car requires a regular replacement of transmission fluid transmission. Such a procedure must be carried out regularly, observing the established and recommended time frames. Peugeot 308 is equipped with Al4 transmissia, requiring timely maintenance. One of the most important operations to maintain the full functionality of the car is to replace the transmission substance ACP.

Checking the level of transmission fluid

The AL4 automatic boxes have a drain plug consisting of 2 parts. The base of the part forms part 1, which is actually a plug. Part number 2 - inside the hollow (tubular) with a set length. This structural element serves as a peculiar indicator by which the level is set. lubricant. At the same time, the second part of the drain plug of the Dr. Peugeot 308 protrudes the amount of the amount of fillible substance. The tubular design provides a sufficiently comfortable drainage of spent oil.

The level of transmission fluid can be checked in such a sequence:

If the lubricant fluid flows the rod, the level was exceeded. Increased amount of transmission substance Peugeot 308 can cause overheating Al4. Such a situation also leads to an undesirable increase in pressure inside the aggregate.

The fact that the level of transmission fluid is below the norm, indicates the appearance of oil through the drain hole drops. Even worse things, if the lubricant does not go out. Low level Oils in the AL4 automatic transmission exposes friction fast wear. In the first and second case, it may be necessary to be partial or complete replacement of transmission fluid.

What lubricant and how often to fill

It is very important to remember that fundamentally different products are used in the manual transmission and in the AL4 automatic box. For automatic transmission, special transmission fluids have been developed - ATF. Such lubricants are elevated requirements for:

ATF for AL4 automatic transmission stabilizes the operation of the hydrotransformer. Special fluid The automatic box reduces thermal loads on friction elements. The oil flies the products resulting from the degree of wear of parts, ensures the correct functionality of the control system.

IN automatic transmissions Mineral, semi-synthetic, synthetic oils. They differ in chemical composition, additives and basic properties. These lubricants also have a different degree of aggressive (destructive) effect on sealing rubber parts.

According to the advice of users and specialists, for the Peugeot 128 automatic transmission, the optimal lubricant is ATF LT 71141. Smooth work Transmission is ensured by a balanced system of additives. The recommended fluid has proven its effectiveness when low temperatures. You can change ATF LT 71141 with longer intervals.

Replacing transmission fluid ACPP Peugeot 308, according to the recommendations of users and specialists, is produced in 30,000-40,000 km. Change the oil through certain intervals should also be tailored to its aging.

Transmission fluid replacement process

In the dry automatic transmission of Peugeot 308 poured 5.85 liters of lubricant. The volume of the fused oil from Al4 is approximately 3 liters. It is necessary to navigate to this quantity, determining the working number of transmission fluid for fill.

Partial oil change can be made if the interval does not exceed 50,000 km of mileage. After 100,000 km, it will take a complete replacement of transmission fluid automatic transmission of Peugeot 308.

At the preparatory stage

A partial or complete replacement of a transmission substance Peugeot 308 automatic transmission is carried out with a raised position of the car. You can use the observation pit, the overpass, lift. For the successful replacement of Al4 transmission fluid, materials and tools must be prepared:

• aTF oil LT 71141 (4 l for partial replacement, 7 l - for complete);
• Padding;
• filter cleaning;
• 4-faceted key on 8 for a drain plug;
• dynamometric keys with heads (10, 19, 27);
• Funnel with an elongated nose (you can wear a rubber tube to a standard funnel);
• Capacity for draining waste liquid;
• Clean rags (rags).

Partially change the lubricant in the gearbox itself. For successful implementation full replacement Need an assistant. It is even better to contact the workshop or service center.

How to conduct a partial replacement

A well-hot car (you need to ride at least 10-15 minutes) is installed on the prepared workstation. Next, the partial replacement includes such steps:

With partial replacement in the transmission Peugeot 308, old and new lubricants are mixed. Mechanical particles and sediments remain, as a rule, inside the aggregate. Therefore, it is not always possible to achieve noticeable changes in the work of the gearbox after such a procedure.

How to carry out a complete replacement

The complete replacement of the exhaust transmission liquid Al4 provides for the maximum possible removal from the unit. A small part of the old substance (0.5-1%) will still remain in the system. But with a complete replacement, it is much higher like the possibility of removing foreign elements.

Change completely transmission fluid can be 2 ways. The first implies the passage of all the stages of partial replacement 3-4 times. So the old substance is extruded new. Lubrication is almost completely refreshing.

However, a second way to fully replace the spent transmission substance is more effective. It is quite laborious, requires certain skills. In this case, the way can not do without assistant and additional equipment. Therefore, often completely change the transmission fluid falls in specialized workshops or service centers.

The full renewal of the lubricant is made using the device for pumping fluid. He pumps out the old product from the system and immediately serves a new one. Two transparent tubes are involved in the device. Each mounted in the pumping circuit or pumping fluid. This allows you to visually assess the condition of moving substances.

The operation of the device is controlled by an assistant. If the replacement is carried out on a service station, the specialist follows the processes in the tubes. On the implementation of the complete replacement indicates the same color of the transmission fluid in both tubes.

Checking the transmission fluid leakage

After partial or complete replacement of the Peugeot transmission lubricant, the Peugeot 308 must be verified in the absence of leaks. To do this, under the front of the machine (in the box area) you need to lay paper or newspapers. They are clearly visible drops of lubricant. It is better to do it in the evening so that in the morning to make sure or the absence of spots.

It is impossible to ignore the resulting fluid flowing from the automatic box. The leakage may be the result of banal inattention (weakly tightened drain plug), and can sign about serious breakdowns. The emerging droplets of the transmission substance indicate a breakdown of the hydrotransformer, clogging of the sapuna, wear of the glands and other problems. Eliminate faults need as early as possible to prevent expensive repair or problem situation.
