Do-it-yourself complete and partial oil change in automatic transmission Mitsubishi Pajero 4

The classic frame SUV Pajero Sport from the Japanese company Mitsubishi is an iconic all-wheel drive car with a modern and very avant-garde design. The model has outstanding characteristics and good maneuverability.

Mitsubishi Pajero Sport I and Sport II have a five-speed manual or automatic gearbox. The new generation Mitsubishi Pajero Sport III is equipped with a 3-liter gasoline engine with a power of 209 hp, which is coupled with an eight-speed automatic gearbox.

Next, we will look at the features of a car’s automatic transmission, as well as when and how the Pajero automatic transmission oil is changed in a five-speed and eight-speed gearbox.

Features of operation and maintenance of Mitsubishi Pajero Sport automatic transmission

So, thanks to affordable prices, technical characteristics and good equipment, the car is becoming more and more popular every year.

As mentioned above, a total of three generations of Pajero Sport SUVs (I, II, III) were produced with a 2.4-liter diesel engine and a 3-liter gasoline engine, as well as with different types of gearboxes (manual and automatic).

Let's move on. The automatic transmission of any car is a rather complex mechanism that requires careful and attentive treatment. Proper operation and timely maintenance will not only extend the life of the unit, but also help the car owner avoid serious breakdowns.

A number of operational features of the automatic transmission (both five-speed and eight-speed):

• design features of the automatic transmission (a cooling system with a radiator is provided; gear shifting is carried out by a control system, etc.);
• main automatic transmission modes (P-parking mode, R-reverse mode, D-drive mode, economical mode, sports mode, etc.);
• rules for driving a car with an automatic transmission (for example, when stopping at traffic lights or in traffic jams, you do not need to set the selector lever to position N, when the car is slipping, it is recommended to turn on the downshift mode, etc.).

We also note the advantages of the new eight-speed automatic unit “Aisin” on the Pajero III compared to the old classic five-speed automatic:

• responds faster to the gas pedal;
• quick switching in the lower engine speed range during acceleration;
• comfortable and dynamic gear shifting;
• fuel economy;
• absence of mechanically controlled levers (control is carried out using a selector and a pair of buttons).

Engine

Now about what kind of oil to fill in the Pajero’s internal combustion engine. As a rule, this is mainly a matter of taste of the owner himself. But the following nuances must be taken into account (otherwise, problems cannot be avoided).

Here are the oils that need to be filled, depending on the type of Pajero internal combustion engine (the table shows several main engines).

Caring for your car is the prerogative of experienced owners who understand the importance of care. By carrying out various procedures periodically, they accumulate valuable experience. Many works, including repairs, such as replacing a Pajero starter or oil filter, are carried out by them without special rules, which makes it possible to save on services at a service station. Work on replacing fluids is no exception in this regard.

Automatic transmission oil Pajero Sport: type and quantity

An important technical task of automatic transmission maintenance is replacing the transmission fluid. In this case, you need to know not only the type of transmission fluid being poured, but also its quantity.

The car’s service book describes in detail both the recommended fluid itself and the amount of ATF, the recommended interval for changing the lubricant in the automatic transmission, etc.

Mitsubishi recommends pouring the original fluid into the five-speed automatic Pajero Sport II Mitsubishi ATF SP II, and into the eight-speed automatic Pajero Sport III Mitsubishi ATF SP III.

Synthetic oil from the manufacturer Mitsubishi is a high-quality long-term lubricating fluid with a set of additives, is heat-resistant and has anti-corrosion properties. The amount of lubricant poured into the Pajero Sport automatic transmission must be at least 6 liters.

Automatic transmission

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

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

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

The high price of services is often explained by workers as the cost of the composition and filter. Here you can offer your own oil, which you managed to buy in the store at 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 approximately 5-6 hours to replace the lubricant in the services.

Methods for renewing lubricant

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 the classic, standard way - partially. In this case, the liquid is simply refreshed. This method has virtually no negative consequences, and the risk of damaging the box due to poor quality service is eliminated.
2. A complete replacement. Here you can’t do without the services of a service station. For such a replacement, special equipment must be used, as well as equipment that helps push the oil. Thus, the old ATP is squeezed out of the box, and the freed space is replaced by new oil.
3. This option is suitable only for experienced car owners. It implies, again, a full replacement of ATP, but on our own.

Partial update

Here's how it's done:

• the crankcase drain plug is unscrewed;
• ATP is drained exactly as much as is released;
• 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). No fundamental changes occur in the box, and the new liquid mixes evenly with the old. This procedure is recommended to be carried out during maintenance not just once, but several times (3-4).

The main advantage of this procedure is that you can do it yourself, without visiting a service center or using someone else’s help. In addition, with this method, a small dose of oil is purchased (it is known to be expensive, but in this case you can buy ATP gradually), and the required additives do not leave the machine.

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

Complete ATP update

Here are the main stages of this method:

• tubes from a special apparatus are inserted into the automatic transmission;
• the car starts;

<li>The process of ATP renewal begins.

The progress of the manipulation must be monitored through a special window: when ATP reaches the desired color, the device immediately turns off. With a complete update, the costs will be higher. You need to buy about 11 liters of ATP so that it is completely enough. They will also charge a lot for the work itself, so you will have to fork out more. At the same time, you can ask the workers to wash the box and check the condition of the filter.

100% replacement of ATP has many advantages, including a significant reduction in fuel consumption. This can be explained by the fact that after the update, losses in the torque converter are significantly reduced, and the response of the machine itself becomes much better. As for the shortcomings, they relate only to the level of qualifications of the service station workers. Choose a quality service and there should be no problems.

Do-it-yourself complete replacement

Here's what to do:

• warm up the box well (driving 5 kilometers will be enough);
• lift the car onto the overpass;
• turn off the engine;
• remove the crankcase plug;
• wait until the liquid drains;
• unscrew the pan, in which there will still be a lot of ATP;
• remove the filter and clean it with gasoline;
• The tray should also be cleaned well and thoroughly;
• insert the filter back;
• refresh the fluid;
• disconnect the tubes;
• put gas or hydraulic hoses on the line and lower the latter into an empty container (preferably a large one so that it fits);
• start the engine;
• As soon as the liquid flows, start monitoring the color - it will acquire a fresh color, which means you need to stop the power unit.

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

After that, all that remains is to put everything back together. It is recommended to diagnose the fluid using the marks after the car has driven for some distance.

The main advantage of this method is its low price. Otherwise there are only negatives. Firstly, you need to have experience, otherwise you can ruin the gearbox. Secondly, even knowing all the specifics of the event, you do not receive any guarantee.

How to find out replacement time

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

Here are some useful tips:

• if the ATP is transparent (even dark), then there is no need to rush to replace it;
• if it is cloudy and there can be no talk of any transparency, then replacement is absolutely necessary.

It’s worth going to a familiar service station for a check - they should tell you everything exactly. The condition of the box can also be determined by the type of transmission. If the liquid has a burnt smell and contains a mixture of shavings and crumbs, you need to urgently sell the car or get rid of it in some other way. In this case, you will need not only an ATF update, but also repair of the automatic transmission (in the best case, it will cost you to replace the filter, seals and gaskets). All this cannot be cheap, and the owner will have a hard time financially.

The 5-speed automatic transmission on 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 unexpectedly “glitches” in the heat;
• under a traffic light, in a traffic jam, the gears change poorly.

You cannot operate the car for a long time in harsh conditions, drag a trailer, or frequently drive through deep snow and mud. Aggressive driving should be avoided when extreme torque is involved. Remember that if, after replacing the ATF, the fluid quickly “ages” and problems with the gearbox do not disappear, the automatic transmission requires more serious care.

What kind of oil to fill

It is recommended to fill the automatic transmission only with original oil from the manufacturer. The table shows its technical indicators.

Changing the oil in the Pajero Sport automatic transmission

For normal operation of the Pajero Sport automatic transmission, it is recommended to replace the transmission fluid every 60-90 thousand km. An oil change in a Mitsubishi Pajero Sport automatic transmission can be either partial or complete. It all depends on the condition of the oil and the mileage of the car.

A partial Pajero automatic transmission oil change can be done independently. With such a replacement, 60-75% of the volume of the old lubricating fluid remains in the torque converter. That is, fluid renewal occurs by no more than 25-40% of the total volume.

It is recommended to carry out a complete Pajero automatic transmission oil change at a service station. Experienced specialists will not only select the right oil correctly, but also, using a special installation for changing the oil in an automatic transmission, will carry out the replacement procedure efficiently and quickly.

A complete oil change is a rather expensive service, since it includes flushing, which requires a large amount of ATF. Next, let's look at the algorithm for partially replacing ATF fluid in a Mitsubishi Pajero Sport box:

• to warm up the ATF fluid, it is necessary to warm up the automatic transmission;
• Next you need to install the car on an overpass, pit or lift;
• unscrew the drain plug and drain the old waste fluid (25% will drain);
• unscrew the fastening bolts of the box pan, remove and wash the box filter (after removing the elements, another 10-15% of the waste will be drained);
  We also recommend reading the article on how to change the oil in the DSG. From this article you will learn how to change the oil in a DSG, as well as what to pay attention to during this procedure.
• clean the magnets located at the bottom of the tray from metal dust or shavings (rinse and wipe the box tray);
• install the washed or new automatic transmission filter in place;
• install the pan using the mounting bolts, replacing the gasket;
• tighten the drain plug of the box and replace its gasket;
• pour new transmission fluid through the technological hole;
• check the “cold” level using the dipstick located in the box;
• check the fluid level “hot” using the dipstick, driving 10-20 km (if there is a need to add fluid to the required level or remove excess).

Checking the level

Now let's talk about the lubricant level. I would like to know how often you check the amount of oil in the Pajero automatic transmission. And how do you do this: do you warm up the machine or not?

The following instructions will show you how to find out the exact lubricant level in an automatic transmission.

1. Start the engine and warm up the machine to 70 degrees Celsius. This is the operating temperature of the box. To do this, you need to press the brake pedal and move the selector handle through all automatic transmission positions. Hold each for five to ten seconds. Move the handle to the “P” position.
2. Place the Mitsubishi Pajero vehicle on a flat surface.
3. Turn off the engine.
4. Open the hood and unscrew the cap with a tip, which is a tool for checking the level.
5. Wipe the tip clean with a rag and lower again.
6. Take it out and see where the grease is. If it is located at the level of the Hot mark, then everything is in order. If it is lower, then you should top it up.

Also pay attention to the quality of the oil in the Pajero automatic transmission. If you see that it has darkened, there is a burning smell, or you observe metallic impurities, then this means that it needs to be replaced.
