How to change the oil in the automatic transmission mitsubishi pajero sport. Do-it-yourself oil change in Mitsubishi automatic gearbox

Automatic transmission (automatic gearbox) is one of the most complex systems of a car, and the number of parts that are part of it can exceed a thousand. Manufacturers put a high operational resource in the automatic transmission, but this does not prevent them from wearing out and breaking over time. Untimely Maintenance Is the most common cause of premature gearbox wear. Directly MOT involves replacement transmission fluid, oil, checking the pressure in the lines, as well as replacing filters. Driving style, operating conditions and weather conditions also have a significant impact on the wear of the automatic transmission.

Timing and reasons for changing the oil of automatic transmission Mitsubishi

• The manufacturing plant recommends changing the automatic transmission oil of the considered car brands every 50-60 thousand km. mileage, but if the operation of the machine takes place in extreme conditions e.g. off-road, the mileage is shortened up to 20-30 thousand km.
• In cold weather conditions, the automatic transmission oil should be changed at the end of winter and the mileage is not taken into account in this case.
• Check the level regularly transmission oil and if it darkens, decreases in level or if there is a burning smell, be sure to think about the need to replace this component. It is not always worth waiting for the recommended time limit, especially if you are purchasing a used Mitsubishi car.
• When low level oil in the automatic transmission, the pump will pump air and soon the transmission will fail.
• Excess required level gearbox oils are also not uncommon. In this case, foaming of the oil and the presence of oil stains on the automatic transmission are inevitable. The surplus in such cases is strongly recommended to be eliminated.

Step-by-step procedure for changing automatic transmission oil in Mitsubishi cars

1. Remove engine protection if present.
2. Find the supply pipe on the radiator, it comes from the box. Use pliers to squeeze out the clamp and remove the tubing. Place the tube in a waste container. A five-liter canister is perfect for this purpose.
3. You cannot do without an assistant in this matter, and at this stage his goal is to start the car in neutral gear. For a minute, but not more, keep the car running. During this time, the pump will spit out oil into the drain container. In forty seconds, a little more than three liters of liquid will enter the canister. The pump will not immediately air due to the upper location of the hose in the box.
4. Switch off the machine and unscrew the drain plug with a 24 wrench. Wipe the plug dry and drain the rest of the oil. Next, tighten the plug and put a tube on the radiator.
5. Use a hose and watering can to pour fresh oil into the box.
6. Start the car and run it a couple of times through the gear selector. Hold each position for five seconds.
7. Remove the dipstick and check that the oil level is between the upper and lower COLD marks. The selector, in this case, must correspond to position N.
8. Warm up the car to working temperature and run the selector in the same way. Check the dipstick and make sure the oil level is between the HOT marks.
9. If you want to make sure for the hundredth time of the correctness of the manipulations done, it is worth driving ten kilometers and making a control check of the oil level.

As a result of the painstaking work done, you will get the automatic transmission to work properly and pleasant trips on your favorite car. The whole procedure takes just over an hour, and in terms of funds, you will only spend on new oil.

Changing the oil in the Mitsubishi Pajero Sport gearbox is most often associated with the repair of the automatic transmission itself, or it is replaced with a new one during work to eliminate oil leaks, since it must be drained for work. The oil in the automatic transmission is poured by the manufacturer once for the entire service life of the car. It is recommended to entrust the oil change in the Mitsubishi Pajero Sport automatic transmission to professionals, but in some cases you can handle this operation on your own.

Functions ATF oils in automatic transmission Mitsubishi Pajero Sport:

• effective lubrication of rubbing surfaces and mechanisms;
• reduction of the mechanical load on the units;
• heat removal;
• removal of microparticles formed due to corrosion or wear of parts.

The ATF color of the oil for the Mitsubishi Pajero Sport automatic transmission allows not only distinguishing between oils by type, but helps to find out in case of a leak, from which system the fluid escaped. For example, oil in automatic transmission and power steering has a red tint, antifreeze is green, and in the engine it is yellowish. Reasons for oil leakage from automatic transmission in Mitsubishi Pajero Sport:

• wear of automatic transmission oil seals;
• wear of the surfaces of the shafts, the occurrence of a gap between the shaft and the sealing element;
• wear of the automatic transmission sealing element and the speedometer drive shaft;
• backlash input shaft Automatic transmission;
• damage to the sealing layer in the joints between the automatic transmission parts: pallet, automatic transmission housing, crankcase, clutch housing;
• loosening of the bolts that ensure the connection of the above parts of the automatic transmission;

The low oil level in the Mitsubishi Pajero Sport automatic transmission is the main reason for the failure of the clutches. Due to the low fluid pressure, the clutches do not press well against the steel discs and do not contact each other tightly enough. As a result, the friction linings in the Mitsubishi Pajero Sport automatic transmission become very hot, carbonized and destroyed, significantly contaminating the oil.

Due to lack of oil or poor quality oil in the Mitsubishi Pajero Sport automatic transmission:

• plungers and channels of the valve body are clogged with mechanical particles, which leads to a shortage of oil in the packages and provokes wear of the sleeve, rubbing pump parts, etc.;
• overheat and wear out quickly steel wheels gear boxes;
• rubberized pistons, thrust discs, clutch drum, etc; overheat and burn out;
• the valve body wears out and becomes unusable.

Contaminated automatic transmission oil cannot fully remove heat and provide high-quality lubricant parts, which leads to various malfunctions of the Mitsubishi Pajero Sport automatic transmission. Heavily contaminated oil is an abrasive slurry that creates a sandblasting effect under high pressure. An intense impact on the valve body leads to a thinning of its walls at the locations of the control valves, as a result of which numerous leaks may occur.
You can check the oil level in the Mitsubishi Pajero Sport automatic transmission using a dipstick. The oil dipstick has two pairs of marks - the upper pair Max and Min allows you to determine the level on hot oil, the bottom pair - on cold oil. Using the dipstick, it is easy to check the condition of the oil: you need to drip oil onto a clean white cloth.

When choosing a Mitsubishi Pajero Sport automatic transmission oil for replacement, you should be guided by a simple principle: it is best to use an oil recommended by Mitsubishi. Moreover, instead of mineral oil you can fill in semi-synthetic or synthetic, but in no case should you use oil "lower class" from the prescribed one.

Synthetic oil for automatic transmission Mitsubishi Pajero Sport is called "irreplaceable", it is poured for the entire service life of the car. Such oil does not lose its properties under the influence high temperature and is designed for the very long life of the Mitsubishi Pajero Sport. But we must not forget about the appearance of mechanical suspension as a result of wear of the clutches with a very significant mileage. If the automatic transmission has been operated for some time in conditions of a lack of oil, it is required to check the degree of its contamination and, if necessary, replace it.

Methods for changing the oil in the Mitsubishi Pajero Sport automatic transmission:

• Partial oil change in the Mitsubishi Pajero Sport box;
• Complete replacement oils in the box Mitsubishi Pajero Sport;

Partial oil change in the Mitsubishi Pajero Sport automatic transmission can be done independently. To do this, it is enough to unscrew the drain on the pallet, driving the car onto the overpass, and collect the oil in a container. Usually up to 25-40% of the volume flows out, the remaining 60-75% remains in the torque converter, that is, in fact, this is an update, not a replacement. To update the oil in the Mitsubishi Pajero Sport automatic transmission in this way to the maximum, 2-3 replacements are required.

A complete oil change in the Mitsubishi Pajero Sport automatic transmission is carried out using an automatic transmission oil change unit, by specialists in the car service. In this case, you will need more oil ATF than the Mitsubishi Pajero Sport automatic transmission can accommodate. One and a half or double volume of fresh ATF is used for flushing. The cost will be more expensive partial replacement, and not every car service provides such a service.
Partial ATF oil change in Mitsubishi Pajero Sport automatic transmission according to a simplified scheme:

1. Unscrew the drain plug, drain the old ATF oil;
2. We unscrew the automatic transmission pan, which, in addition to the bolts holding it, is processed along the contour with a sealant.
3. We get access to the automatic transmission filter, it is advisable to change it with each oil change, or rinse it.
4. At the bottom of the pallet there are magnets that are necessary for collecting metal dust and shavings.
5. We clean the magnets and rinse the pan, wipe dry.
6. Install the automatic transmission filter in place.
7. We install the automatic transmission pan in place, replacing the automatic transmission pan gasket if necessary.
8. We tighten the drain plug by replacing the gasket drain plug for automatic transmission.

We fill the oil through the technological filler hole (where the automatic transmission dipstick is located), using the dipstick we control the oil level in the automatic transmission to a cold one. After changing the oil in the automatic transmission, it is important to check its level after driving 10-20 km, already with the automatic transmission warmed up. Top up if necessary. The regularity of oil changes depends not only on the mileage, but also on the nature of the ride on the Mitsubishi Pajero Sport. You should be guided not by the recommended mileage, but by the degree of contamination of the oil, systematically checking it.

Changing grease in Pajero

An oil change in Mitsubishi Pajero is carried out as planned, like the rest of the procedures for a thorough change of all vehicle fluids. The obligation of this event does not cause doubts for any experienced motorist, especially since it is written in the Pajero service book, although the timing does not always correspond to reality.

Mitsubishi Pajero Sport do it yourself lubricant replacement

Renewal of working fluids should be carried out regularly. The event affects the following components and elements of the SUV:

• brake reservoir;
• radiator;
• front. and ass. differential;
• handout;

Automatic transmission

It is advisable to change the transmission in the automatic transmission at the service station. An automatic transmission is a complex mechanism that requires proper maintenance. If the car is still under warranty, then you need to use the services of an official service. If not, and "Padzherik", for example, of the Arab assembly, then you will have to look for the most acceptable options.

Although, you can call the official service and explain the situation by phone. They will count, and within 10 minutes they will answer how much the replacement will cost.

In most cases, replacing a lubricant in official services is several times cheaper than in a garage. But it depends on the specific place of residence. It also happens that garage services cost almost half the price.

The high cost of services is often attributed by employees to the cost of the composition, filter. Here you can offer your own oil, which you managed to buy in the store for a low price. Many service stations agree to this option, some do not.

By the way, in Pajero, the automatic transmission filter is designed for the entire life of the car. So it is updated only in rare cases.

As for the work time, it takes about 5-6 hours to replace the lubricant in the services.

Grease renewal methods

Now about the ways in which you can update the transmission in the Pajero box. There are 3 main scenarios for the development of events.

1. The oil is changed in a classical, standard way - partially. In this case, the liquid is simply refreshed. This method has practically no negative consequences, and the risk of spoiling the box due to poor-quality service is reduced to naught.
2. Complete replacement. Here one cannot do without service station services. With such a replacement, special equipment should be used, as well as equipment that helps the oil to push through. Thus, the old ATP is squeezed out of the box, and the vacated space is replaced with new oil.
3. This option is only suitable for experienced car owners. It implies, again, a full-fledged replacement of ATP, but on its own.

Partial update

Here's how to do it:

• the crankcase drain plug is unscrewed;
• ATP is merged exactly as much as it comes out;
• the plug is put in place;
• the amount of drained liquid is measured, and then exactly the same amount is poured into the box.

This method allows you to refresh almost half of the transmission fluid (ATF). There are no drastic changes in the box, but new fluid mixes evenly with the old one. This procedure is recommended to be carried out during maintenance not once, but several times (3-4).

The main advantage of this procedure is that it can be done with your own hands, without stopping by the service and without using someone else's help. In addition, with this method, a small dose of oil is bought (it is known to be expensive, but in this case you can buy ATP gradually), and the mandatory additives do not leave the machine.

Replacing TJ in the table

There are also disadvantages compared to a full replacement. They relate primarily to higher oil consumption, because such a procedure must be carried out several times, and a complete replacement is carried out only once, after several hundred kilometers.

Complete ATP Renewal

Here are the main stages of conducting this method:

• tubes of a special apparatus are inserted into the automatic transmission;
• the car starts up;
• the process of ATP renewal begins.

The course of manipulation must be monitored through a special window: ATP reaches the desired color - the device turns off immediately. With a complete update, the costs will already be higher. You need to buy about 11 liters of ATP to be enough. They will also take a lot for the work itself, so you will have to fork out. At the same time, you can ask employees to rinse the box and check the condition of the filter.

100% replacement of ATF has many advantages, including a significant reduction in fuel consumption. This can be explained by the fact that after the upgrade, losses in the torque converter are reduced to a large extent, and the response of the machine itself becomes much better. As for the shortcomings, they relate only to the qualification level of the workshop workers. Choose a quality service and there shouldn't be any problems.

Complete DIY replacement

Here's what to do:

• warm up the box well (driving 5 kilometers will be enough);
• lift the car to the overpass;
• turn off the engine;
• remove the crankcase plug;
• wait until the liquid is drained;
• unscrew the pallet, in which there is still a lot of ATF;
• remove the filter and clean it with gasoline;
• clean the pallet well and thoroughly;
• insert the filter back;
• refresh the liquid;
• disconnect the tubes;
• put on the gas or hydraulic hoses on the highways and lower the latter into an empty container (it is better to immediately large to fit);
• start the engine;
• as the liquid goes, start monitoring the color - it will acquire a fresh color, which means that it is necessary to stop the power unit.

Advice. It is advisable to use the help of an assistant. Let him sit behind the wheel and turn off the engine as soon as he receives a signal from you.

After that, it remains only to collect everything back. It is recommended to be sure to diagnose the fluid by the marks after the car has traveled some distance.

The most important plus of this method is low price... Otherwise, only cons. First, you need to have experience, otherwise you can ruin the gearbox. Secondly, even knowing all the specifics of the event, you will not receive any guarantee.

How to find out the replacement time

Yes, many will be interested in knowing this. The fact is that the recommendations indicated in the passport data are completely untrue, since the car is not operated in ideal conditions. So you have to follow this yourself.

Here are a few useful tips:

• if ATP is transparent (even dark), then you should not rush to replace it;
• if it is cloudy and there can be no talk of any transparency, then a replacement is needed in mandatory.

It is worth going to a familiar service station for a check - they must say everything for sure. By the type of transmission, you can also determine the state of the box. If the liquid has a burning smell and contains a mixture of shavings and crumbs, it is urgent to sell the car or dispose of it in some other way. In this case, it will be necessary not only to update the ATF, but also to repair automatic box(at best, it will cost to replace the filter, oil seals and gaskets). All this cannot be cheap, and the owner will have a hard time financially.

The 5-speed automatic transmission for Pajero 4 and Pajero Sport requires periodic inspection, at least every 5 years.

In addition, the following points may indicate a problem with ATP:

• the machine suddenly "glitches" in the heat;
• under a traffic light, in a traffic jam, the speed switches poorly.

You cannot operate the car for a long time in harsh conditions, drag a trailer, often drive in deep snow and mud. Aggressive driving behavior should be avoided when torque limits are involved. Remember that if, after replacing ATP, the fluid quickly "ages", and the problems with the box do not disappear, the automatic transmission requires more serious care.
