Contract automatic automatic automatic automatic transmission automatic 40. Typical errors allowed when replacing oil in Mercedes W210 automatic transmission

Good all day. The topic of today's article is to replace the oil in Mercedes W210 automatic. The article contains step-by-step photos and video instructions for which any motorist will be able to replace oil with your own hands.

To replace oil in automatic transmission 722.6 we need:

Consumables:

- oil with tolerance 236.12 ( A001 989 68 03) I always poured FEBI

- filter automatic transmission

- Set of pads (pallet and plum stop)

Tool:

- probe to change the oil level (it happens universal for boxes 722.6)

- Fluor for filling oil

- Butter drain tank

- Set of Torx keys (asterisk)

The procedure for the replacement of oil in automatic transmission 722.6.

- We drive the car to the pit or the lift.

- unscrewed drain plug And in the pre-prepared container drain the oil.

- We unscrew the pallet and drain the oil from it (the design is such that the plug is far from all the oil).

- Remove by pulling down the filter (butter will also run).

- In early boxes (until 1998), on the "Bublik" automatic transmission is also a plug for oil drain (drain it).

- Change the filter to the new one.

- Remove dirt from the pallet.

- Change the pallet laying to the new one.

- in the pallet, before installing, if it is notIt makes sense to put a magnet from the hard disk (it will collect on itself the chips, and it will not so much to pollute the filter).

- We screw the pallet into place, wrap the drain plug and the plug of the automatic transmission.

- IN motor compartment Remove the plug and poured through the funnel A little less oil than we merged.

- Run the engine, run down the lever on all positions of the selector (keep 4-6 seconds in each position) and put it in parking.

- Do not radically measure the engine oil level (look at the cold scale) if the level is normal to check the level of hot! If the level differs from the norm, it is necessary to adjust it, topping or merging the oil.

- Drive about 20 km. We put the car on the horizontal surface and change the level of oil "on the hot", it should be between the upper marks.

- If you need to correct the oil level. Congratulations, replacement completed. You have just saved about 2000-3000 rubles.

Here you have a video on the replacement of oil in the automatic transmission:

Typical errors allowed when replacing oil in the MERCEDES W210 automatic transmission.

• replacing the oil without probe (pour, how much I slept) there is no guarantee that before your replacement level in the box was correct.
• replacing oil on oil, not having tolerance (may refuse a box, and its repair is expensive).
• replacing the oil without replacing the filter (the result of the box will get into an "accident", as the filter scores and the oil starvation begins).
• the incorrect change in the oil level (did not drive the lever on all positions of the selector or measured by the car standing under a slope).

Replacing oil replacement Does it make sense?

In many stations, it is proposed a service for replacing oil to the automatic transmission. The essence of this method is the following - in the circuit of cooling the oil inspection, the adapter and oil from the box are supplied to a special container and at the same time replaced new. It looks very impressive - dirty oil went, then it went sharply clean, and the car owner convinces that the oil is completely replaced by the automatic transmission and the automatic transmission. The result in 20 000 - 40,000 box (722.6) will fall into an accident, since it does not have enough oil pressure due to the filter stuffiness!

Friends Replacing oil in automatic transmission, this is a divorce for money, and the way to sell the client 2-3 oil volume without making regulatory work on replacement. You need to change the oil strictly by factory instructions.

The oil change interval and signs that the oil is better to change.

The plant has a service life of oil in automatic transmission - 60,000 km.

If the box begins to kick when switching or a long time to think better change the oil without waiting for the service interval of replacement.

I have everything today. I hope that after familiarization with our instructions, you will not have difficulties with the replacement of oil in the Mercedes W210 automatic transmission.

In winter mode vehicle Starts from the 2nd transmission and uses less aggressive mode.

Transmission received an update in 2001. It was eliminated by the shortcomings with a sleeve, the valves, bearings, software, internal materials, glazes have been added and added the possibility of manual gear shift (Alya TipTronic).

Description

1996 became a turning point for Mercedes from the point of view of configuration by automatic boxes. Instead of morally outdated hydraulic automatic transmission 722.3 - 722.5 on the conveyor, the first electronic automatic box with a torque converter blocking was entered. This box was installed on many Mercedes from W163 to W463 and W639 Viano.

Upon completely banal design flaws - a weak gliding sleeve is applied in the interface of the input and output shaft - these boxes "flew" one after another. And this sleeve gave earnings to masters until 1999. This is unfortunately for owners of Mercedes. Almost all cars of those years of release passed through the hands of masters, with rare exceptions. Especially quickly became repaired by Mercedes with a large engine. After the destruction of the sleeve of the shafts due to the strong backlash, the insides were smashed.

The worst thing is that as previously it was noticed, we do not know what is happening inside the box. And if there are practically no external manifestations or they are invisible, then the owner of such a car will ride to a victorious end. So in the case of a sleeve. At the initial stage was not noticeable. Only after some time the box went into defense and moved to ride only on the second gear. Further, the transmission began to noise much. And only at that moment the car was delivered to the service. But it was too late to drink Borjomi. Why all the time and pay attention: they felt something wrong - run to the master for consultation. Only so you can save a bunch of money. The task of our masters does not paint more money, but to have a permanent job in the form of preventive measures. It is significantly cheaper and easier to morally for you.

In 1999 by technical replacement The unreliable sleeve was replaced with a needle bearing with Teflon Ring, and the problem disappeared. Indeed, sometimes it costs simple consumers an exploitation of the initially flawed aggregate. In the same year, also for technical replacement instead of the sliding sleeve in the solar gear MPLS / HPLs put the bearing.

Until 2001, transmission 722.6 sinned the coupling of the free move of the clutch housing K1 (external manifestation in the form of shocks during switching 1 - 2), as well as MPLS / HPLS coupling (shocks when turned on 3-4). And these clutches were included in the design of the box exclusively to create comfortable regime Shift.

Another modernization of 722.6 was subjected to the same 2001. By this moment, all the leading developers of the automatic transmission of one of the tasks were the possibility of fuel economy. To solve this problem in 722.6 began to reduce the shift time. It was for this that special friction discs were applied in some packages. The specialty consisted in reducing their thickness and one-sidedness. The weakening of the structure immediately affected the "lugouts". Especially slipping or sharp acceleration (why all the time I speak about the meaningful application of Kikdaun!) There were direct dear to the master for repairs.

Not a very well-designed transmission spool 1-2 transmission in the hydraulic block, especially when aggregating with diesel engineAlso failed. Externally, this defect manifested itself with a slip when switching 1-2. Another weak point is an electronic board with the sensors of the input and output shaft. This defect makes the box go into defense and move only on the second gear. If diagnostics gives a malfunction code for these sensors, the defect is eliminated without removing the automatic transmission.

Service

Very often, when diagnosing in services, due to small things, people are bred to repair automatic transmission. Request a printout of errors with check with the above or refer to the proven service station.

Repair or change?

Let's start with the fact that most types 722.6 are no longer supplied in spare parts new. Rebilt goes, i.e. Restored at the factory of the box. For example, automatic transmission for type 210.065 has a catalog number 210 270 77 00 80, where 80 or 87 means that it is restored. At the same time, for the refund of the old box, Mercedes returns you money. Using the example of the same box - the price of it is 3344 euros, for the return of the old you will receive 1150 euros. Now we consider what repairs will rise. I will give a simple calculation:

remove / put automatic transmission. According to the standards of ASRA, an average of 6 normochas, i.e. about 270 dollars;

disassemble / collect automatic transmission, repair 6-8 norms, we take 300 dollars for simplicity;

8 liters of oil for $ 14 per liter, totaling 112 dollars;

packing kit 140 270 65 00 - 105 dollars;

filter 140 277 00 95 - 15 dollars;

flex fee 140 270 08 61 - $ 200;

primary shaft 140 270 12 25 - 393 dollars;

secondary shaft 220 270 00 26 - 668 dollars;

pieces of twenty friction discs (for example, the discs of the package B1 140 272 00 25) 20 to 10.63 dollars;

pieces five metal disks (for example 140 272 03 26) 5 to 15 dollars;

free move coupling 220 270 01 31 - $ 36;

planetary mechanism 140 270 17 43 - 273 dollars;

solar wheel 140 270 15 44 - 245 dollars;

other little things (clamps, seals, buckwheat bolts) - Well, even let the bucks for 10;

Total $ 2915 on the example of the automatic transmission from the 500th stroke. I do not try to convince you that this is a universal set for repairing 722.6 old version. It is usually less, but it happens more. I would like to add that the motors are smaller and the cost of shafts is significantly lower.

What are the advantages and risks when buying a new or restored automatic transmission at the plant? Of the films known to me, the replacement of boxes for new or recovered times five nodes did not even hurt even warranty period. Fortunately, people came to competently and replaced from the officials, since the guarantee on the node can be obtained from Mercedes only when it was replaced by an official dealer.

Repairs

So, the decision is made - a box for repair. Do not hurry with the solution where this repair is performed. Criterias of choice:

1. Timing. If the repairmen hold spare parts in stock - they go fine. What breaks in boxes and what needs to keep in stock they know. With the debt, the time from the delivery of the car to repair before receiving two - three working days, unless of course there is no queue. Order parts to Germany after a defective - an option that makes doubt the preparedness of the service.

2. Price. Fear crossing prices as well as low prices. Normal price of repair box 722.6, if no replacement of a transformer or EGS block is required - from 2000 bucks per box new version up to 3000 per box old version. What makes this price.

If you offer all the same to do much cheaper - refuse. Savings in this situation are possible due to the fact that you will be put on not new shafts, but are streamlined from the shafts of the old sample worked with the sleeve. The fact is that with a layer of metal removed and superficial hardening - cementation and landing under the bearing will certainly not from raw metal, but not the hardness. Not to mention the fact that landing in primary shaft Under the outer clip of the bearing will be performed rather definitely not on the grinding machine, but on the tokar - in ten cases out of ten, the hole was conical. I had to see such trees - it will work, but not long. In principle, this option is acceptable if the car goes for sale and you agree with the promotion of Louis XV: "After us, though the grass does not grow!" It is clear that all of the above belongs to the boxes of old versions working on the interstal sleeve.

3. Warranty. Year is a normal warranty. Mileage is usually not negotiated, because a competently renovated unit is essentially more perfect than your box at the moment when the car has gone from the conveyor. The reason is that the design thought does not stop for a minute. If you look into the EPC spare parts catalog, you can see that only oil filter For all the time of release 722.6 I have not changed. Nevertheless, the remaining details were subjected to replacing numbers other than ten times. Those. Mercedes releases the next version of some detail, it takes time and reports are received from the services - nichrome, it still works badly! Change again - and again something is wrong. And so while the reliability of the node will begin to arrange. Along the way, they are trying to modernize something, make it easier to reduce, make it easier - and again instead of reliable get weakness. Everything repeats again and again. Ideally reliable and perfect box 722.6 and was not created. At first, the interval sleeve was donimal - they coped (put the bearing), began problems with planetary. They were decided - hydrotransformers were sprinkled (to reduce fuel consumption in the EGS blocks made new logic and the locking algorithm). And so the eternal gemmore! Therefore, the freshly limited box is essentially the most perfect node, because It is styled by the latest versions of the details.

And last. Honestly, I do not believe in the repair of automatic transmission as the correct operation. More precisely, if you perform everything according to the rules, the repair will be released in the amount comparable to the cost new box or more expensive (it is no secret that the cost of the part separately from the node is 200-250% of its value as part of the node). When running 200 thousand km, it requires replacing the automatic transmission of automatic transmission, a hydrotransformer, an EGS block with the latest software version, well, of course, most of the swirl and rubbing parts. But only the first three positions are already pulling on three thousand bucks. But this is only my opinion. It is based on the fact that I compared the operation of the automatic transmission after the bulkhead with the old hydraulicone and the EGS unit and with new ones. As they say in Odessa, these are two big differences. And I will not accept sarcasm on the topic that we do not know how to propagate the hydroblock prophylaxis: Increased gaps in plunger pairs and "tired" springs will never give the perfect switching, no matter how lowered hydroblocks.

If you have a box dorestayling: the geometry of the details is such that it is possible to crush the landing in the primary shaft and grab the neck of the secondary shaft so as to redo the old shafts for the installation of the bearing. But on turning machine Ensure the perfect landing is difficult, especially when it comes to the hole in the primary shaft: the surface is cemented, the cutter "floats" and often the hole is obtained by conical. On reliability and guarantees in such a situation, it is difficult to speak. In 9 cases out of 10, such an operation is doomed to failure, this output only if car will go for sale.

As a rule, there are no restrictions on the post-repair period. Without running - sat down and drove, as always went. Take advantage calmly if you will be offered to replace the oil in order to comply with the warranty. So you will be calmer.

If it is impossible to start the machine, tug on a neutron at a speed of up to 50 km / h to a distance of no more than 50 km.

Spare parts

Typical set of overhaul consumables automatic transmission 722.6 includes: Overhal Kit, then you mean, repair kit with gaskets and glands), a set of frictional (in particular clocks of the package K2), steel discs (mostly k2, different thickness for different modifications 722.6 Depending on the torque of the engine, as cm above), the pallet laying, the filter.

Where installed

Even with complete synchronization, easy shift switching and enjoyable clutch control, the switching process remains manual work, which for many drivers hits fear. Therefore, Mercedes-Benz can find a useful unit that will unload the driver from the shift process: automatic transmission. She solves independently when and with what transmission to move. In this case, takes place, as a rule, the choice between four front transmissions. And in automatic gearboxes fourth generationwhich Mercedes-Benz launched into production from the spring of 1995, the five main speeds of speed are considered to be a measure of all subsequent cases. Such new E-class top models as E 320 and E 420 serially exit from the assembly conveyor with the latest 5-speed gearbox with electronic control.

Compact 5-speed gearbox in section. 1. Transducer torque, 2. multi-disc clutch, 3. Computer planetary gears, 4. gear, clutching for parking time, 5. Output shaft flange, about the rotary lever of the pre-selection lever on the middle console.

For five front gears in the new generation of automatic boxes, you must have only three planetary levels and six switchable elements. Former boxes with the same number of front gears had four planetary levels and seven switchable elements. And as usual in planetary transmissions, individual gear steps were achieved due to durable adhesion with freely rotating elements. Instead of the Mercedes-Benz engineers previously used for this purpose, Mercedes-Benz engineers were applied in a new generation transmission only multidisk couplings and friction multi-disc brakes. Advantage: Due to the controlled clutch, you can use these elements switchable under load and the quality of switching the entire service life of the gearbox to support high level. A decrease in the number of planetary wheels has made it possible to obtain a particularly compact design form: no 5-speed gearboxes of other manufacturers, no 4-speed automatic transmissions in this class of torque and are not close to this new Mercedes-Benz switching unit. It has only 600 mm long and thereby almost 150 mm shorter than comparable other models of automatic boxes. Only the former 4-speed automatic transmission differed compactness - naturally, due to the absence of one transmission and clutch for blocking the torque converter. Also, when comparing the masses ahead, a new 5-speed gearbox. With its 80 kilograms, it is almost a third less by weight in comparison with other gearboxes of a similar type. Reducing the mass, for example, provides Mercedes-Benz due to the use of sheet steel typical of it, which replaced cast-iron and wrought parts.

The disassembled 5-speed gearbox in comparison with the former automatic boxes has a markedly reduced amount of parts.

Thanks to its modern design, this automatic box consists of only 630 separate details. This is 45% less than that of comparable boxes with 5 speeds.

So operates automatic transmission
The core of the automatic box is considered the so-called sets of planetary gears. The set consists of one gear, around which three other gears rotate. Due to this location, the annular gear (central wheel) internal engagement is inside out. Ingenious in such a box is a method based on the switching of such gear sets. The change in the transfer is carried out only with the retention or release of the parts of the planetary set. Thus, switching is performed without interrupting the stream of power from the engine to the wheels. Multi-disc clutches and friction brakes with hydraulic control. To hold a multistage gearbox, three sets of planetary gears carry out serial switching. Thus, a three-speed automatic box with a reverse transmission appears.

The planetary gearbox has all gears constantly in engagement. Various gear steps are created without interrupting the power flow due to actuating or holding the central wheel, planetary wheels or ring gears. 1 Details, 2 Details held in motion.

Check automatic transmission
When checking the functioning, and especially when carrying out the necessary repair work, even experienced lovers must comply with strict borders. For speed, a special device is needed and a good practical experience. So, pass the warranty workshop, only trained specialists, installation and repair work. Below is a pair of simple checks that will at least help narrow the discourse of defects.

You must check the ATF level when faults appear in the first place.
During a trial trip, you can check the switching points. For this, the workshop has accurate tables.
Adjusting the control cable between the gearbox and the clutch is the most important condition for impeccable work.
Measuring the working, regulating and modulating pressure is a workshop. Many pressure parameters can be adjusted.
For judgment on switching processes, the idle rotation speed should be accurately aligned.

When the ATF loss appears in automatic box Gear Throw your gaze under the bottom of the car. If the gearbox is grose, possible reason Already detected.

Checking the oil level in the automatic transmission
The oil level in the automatic transmission should be checked only after changing the oil or when there is a doubt about its tightness. The prescribed oil level is very important for the impeccable functioning of this gearbox. Therefore, such an inspection must be performed with special care.

With too low oil level, the clutch does not have a power closure and slipped, since the oil pump sucks the air. The resulting pricing causes premature wear of the gearbox details. In addition, oil decomposes, hardens and forms oil sludge.
With a too high level of oil, it takes greatly through rotating parts, and as a result, it is significantly heated. It causes a similar impact as too low level Oil, - namely, suction air.

ATF-bulk tube is in the engine compartment. Also, the oil level is also checked by oil probe.
