Do-it-yourself complete and partial oil change in automatic transmission AL4

Today we will talk about changing the oil in an automatic transmission from the French manufacturer al4. In Russia it is also called DP0. This four-speed transmission has features in the form of knocks and noises that the manufacturers have not corrected. Automatic transmission was born in 1999. Then the Peugeot-Citroen plant finalized and released a new version of DP2, DP 8. Compared to the latest transmissions, this automatic transmission can last 250,000 or more kilometers with proper care.

Which cars have the AL 4 gearbox installed?

The Al4 automatic transmission transmits torque up to 210 Nm. The manufacturer created it for cars with front-wheel drive and a 1.4 or 2.0 liter engine. Such small cars could rush around the city, not inferior to cars with a large volume. But the manufacturer had to tighten the Al4 torque settings so that the unlucky car enthusiast would not gouge the back cover and kill the machine.

The manufacturer was the Peugeot-Citroen plant. The Al4 automatic transmission, jointly produced by two French auto manufacturing companies, can be found on the following vehicles.

The table shows the most popular cars on which the box was installed. This machine is very popular among Russian motorists and is also repairable. Spare parts for Al4 automatic transmissions are publicly available at low prices. You can also easily find a contract machine if your original one is out of order forever.

Attention! The Al4 automatic transmission is designed only for original oil, which is based on Dexron III standards.

Write in the comments if you have a car with an Al4 automatic transmission and what problems do you experience during operation?

Complete replacement

The entire lubricant can be changed only in a technical center where there is special equipment. The technician connects the transmission fluid supply pipes to the cooling radiator and pumps new oil through a vacuum compressor until it is completely renewed. Depending on the degree of contamination of the liquid, the procedure takes from 1.5 to 2 hours.

Has the automatic transmission in your Peugeot 308 started shifting poorly? This is a sign that it's time to change the oil. If you are not sure that you can handle this yourself, contact DDCAR technical service specialists for help. When changing automatic transmission oil, we use only original fluids recommended by the French automaker Peugeot Citroen.

Transmission oil change interval for AL4 automatic transmission

According to the manufacturer, the Al4 automatic transmission does not require lubricant replacement. However, I would not trust such loud assurances. It is clear that this is a marketing ploy.

Therefore, when the mileage of a car with an Al4 gearbox reaches 30 thousand kilometers, I advise you to replace the transmission fluid. At this time, you can only do a partial oil change. And I recommend doing a complete one, using the replacement method, after a run of 60,000 kilometers.

Under extreme operating conditions, I recommend reducing the time. Or change it immediately if you experience the following symptoms of oil starvation:

• noise or vibration of the Al4 automatic transmission at intersections, while idle and at idle;
• knocking noises that occur more often than usual;
• overheating of the box, despite the cool season. In summer, the Al4 automatic transmission often overheats and the ECU fails. It is advisable to install an additional cooling radiator in hot regions of Russia.

Attention! I will not tire of repeating that timely oil changes will eliminate many problems that arise due to driver negligence.

How to change the oil in a Peugeot 308 automatic transmission?

Replacing used transmission fluid yourself is not that difficult. You need to prepare the tools, purchase the oil recommended by the car factory and warm up the box to 60 degrees by idling or taking a short trip by car. At home, it is difficult to determine the temperature of an automatic transmission, so technicians recommend waiting for the engine fan to turn on.

Practical advice on choosing oil in an AL4 automatic transmission

To change the oil to Al4, you need to approach this with the utmost seriousness. The automatic transmission only likes the Dexron III standard. And various cheap fakes will lead to a quick overhaul of the already capricious box from the French.

Please note that an older device requires frequent replacement and is most in need of the original fluid.

Original oil

Use mineral based oil. For example, Ravenol ATF Dexron III. They are sold in four-liter cans. One bottle is enough for a partial oil change in Al4.

Buy oil only in specialized stores. This way you will avoid fakes.

Write in the comments what oils do you use to change transmission fluid in Al4?

Analogs

If mineral oil for Al4 cannot be found in the owner’s city, then the following types are suitable:

• Esso;
• Mobil ATF 71141.

Use them only if you really don't have the original. Change the Al4 filter device along with the liquid. Do not forget to blow air through the radiator so that the cooling system always operates properly.

Maintenance features of the DP0 machine

Representatives of the RENAULT concern have not established mandatory deadlines for replacing transmission fluid in automatic transmissions. It is believed that the degree of aging of the lubricant is controlled automatically by the on-board computer. The manual stipulates the following: if leaks occur, you need to add additional working fluid to achieve the required level. The recommended oil for automatic transmission is DP0 brand Elf RenaultMatic D3. It should be remembered that this brand of lubricant is not compatible with Elf RenaultMatic D2 consumables.

Despite the recommendations given by the RENAULT Laguna dp0 manual, experienced car owners are advised to take into account the special operating conditions of cars on Russian roads in difficult climatic zones. Therefore, replacing ATP transmission oil should be carried out after a mileage of no more than 60 - 80,000 km.

Checking the level

The Al4 automatic transmission, as I already said, does not like oil starvation. Therefore, I recommend checking the lubricant level in the box every 10,000 kilometers. Unfortunately, the machine does not have a probe for easy checking. Therefore, the procedure will proceed as follows:

1. Start the engine. Warm up Al4 to 70 degrees Celsius. This is its operating temperature.
2. Take the car for a ride and place it on a flat surface.
3. Do not turn off the engine. Set the selector lever to “P” mode.
4. Wear gloves as you may get burned when the lubricant comes out.
5. Get under the car and place a container under the drain hole.
6. Unscrew the Al4 drain plug.
7. Watch the oil pour out of the hole. If it drips, then the level is normal. If the hole is dry, add lubricant.
8. Add grease through the Al4 drain hole under the hood. You will need about a liter.
9. Drive the car again and, placing the car on a flat surface, check the level.

Have you already checked the level yourself on the Al4 box? Or do you take the car to experienced mechanics in such cases?

Reasons for automatic transmission going into emergency mode and ways to reset the error

What materials do we need to change the Al 4 automatic transmission lubricant:

• original mineral oil based on Dexron III;
• Al4 oil filter under catalog number 144010;
• gasket for the pallet (set number 144002);
• seals for drain and grease plugs. Because they tend to dry out and crack. This will lead to the hole not sealing properly. The oil will drip;
• gloves;
• lint-free cloth;
• container for drainage;
• wrenches and ratchet sockets – sets;
• a five-liter bottle will be needed to change the liquid using the substitution method.

Once you have prepared all the tools, you can start changing the lubricant to Al 4 DP 0.

Do-it-yourself oil change in automatic transmission Al4

Write in the comments how you prepared to change the oil in the Al 4 automatic transmission of your car?

Changing the fluid in an automatic transmission consists of several stages. Each of them will be described in more detail in a block dedicated to one of the process steps.

Draining old oil

Let's start by draining the used fluid from the Al 4 automatic transmission. It is necessary to completely drain all the oil from the automatic transmission so that mixing does not occur.

Procedure steps:

1. Start the engine. Take the car for a drive to warm up the automatic transmission.
2. When the temperature rises to 70 degrees, stop in a pit or place the car on an overpass.
3. Turn off the engine and take the drain container. Wear gloves.
4. Unscrew the drain plug and wait until the Al 4 liquid is partially drained.
5. After this, unscrew another glass inside the drain hole. Oil will gush out. About three or four liters should pour out.
6. When the hole is dry, loosen the bolts on the pan and remove it.

It's time to clean the tray and magnets.

Washing the tray and removing chips

Rinse the Al 4 pan in kerosene or a special liquid that can be found in any auto store. Do not forget to remove the old gasket, and the place where it stood will need to be degreased.

All diseases of the Citroen C4 automatic transmission and their repair

Clean the Al 4 magnets from any metal shavings adhering to them. If these wear debris are not removed, they will quickly clog the new filter device.

After you set the pan to dry, you can proceed to replacing the filter on the Al 4 automatic transmission.

Replacing the filter

The procedure for replacing the filter will be as follows:

1. Unscrew the bolts that hold the filter device on the Al 4 automatic transmission.
2. Take it off.
3. Install a new one.

If the Al 4 gas turbine engine leaks lubricant, then I recommend immediately changing the Teflon o-rings. To do this, you will need to unscrew the rear cover bolts, remove and put back new small and large rings.

Filling with new oil

After you have replaced all the components with new ones, you need to begin installing the parts in the reverse order.

1. Place the gasket on the tray and cover it with silicone.
2. Press Al4 firmly to the bottom of the automatic transmission and tighten the bolts.
3. Change the seal on the Al4 drain plug and tighten it.
4. Or remove the battery and stand to get to the filler hole. Or find a long hose and insert the neck of a funnel into it.
5. Insert the other end of the hose into the grease fill hole.
6. Fill a four-liter canister of lubricant.
7. Screw in the drain plug Al4, not forgetting to change the seal on it.
8. Start the engine and drive the car for 10 kilometers.
9. Stop on a level surface and check the level.

I have already written about how to check the amount of lubricant.

Have you already done a partial fluid change on the AL 4 automatic transmission yourself? How was the procedure? I will wait for your answer in the comments.

RECOMMENDATIONS FOR AL4 automatic transmission OWNERS:

• Warm up the AL4 gearbox before driving . Press the brake pedal, move the automatic transmission control lever from “P” mode to “D” mode, hold for one minute, then switch to “PRND” modes.
• Start moving smoothly, without sudden acceleration. You can begin to actively accelerate after the engine and gearbox have warmed up to operating temperatures.
• Do not allow the car to slip. If you get stuck in snow or mud, ask someone to help pull the car out. Even if you have to pay assistants, it will cost a hundred times less than a possible overhaul of the automatic transmission. This recommendation applies to Peugeot 307 automatic transmission.
• The automatic transmission must have a normal oil level . There is no dipstick in the box. Pay attention to the presence of oil smudges on the body of the automatic transmission (Renault Megane automatic transmission, Renault Megane 2 automatic transmission, etc.).
• If an automatic transmission, for example, the automatic transmission of a Peugeot 308, “falls out” into emergency mode , i.e. forcibly engages third gear and the “PRND” symbol lights up (“S” and “*” flashes) - no need to panic, this does not mean that AL4 is “coming to an end.” This is a signal that the control oil pressure in the automatic transmission is below normal. Therefore, contact the service as soon as possible.
• Check the condition of the engine mounts . Their wear can be indicated by increased vibration and shocks when shifting gears. Change them promptly.
• Monitor the temperature of the engine and gearbox . The air conditioner and coolant radiators must be clean. Wash them once every six months.
• The automatic transmission must have a normal oil level . You can check it in AL4 only at a car service center by following a special procedure; there is no dipstick in the box. Pay attention to the presence of oil smudges on the automatic transmission housing.
• The brand of oil filled into AL4 is only MOBIL ATF LT71141 (for DP0 - ELF RENAULTMATIC D3 SYN).
• Service the gearbox every 20,000 km. Perform a partial oil change in the automatic transmission and computer diagnostics of AL4. In total, the box contains 6.5 liters. oils Due to the design features of the automatic transmission, the oil is not changed completely, but only 3-3.5 liters. Call +7 495 7451002/+7 495 7551002. From 9:00 to 19:00 Moscow time. Perhaps, at this moment, we have already learned how to connect your automatic transmission with a 100% ATF replacement device.

Why every 20,000 km? After all, the manufacturer claims that the transmission is not serviceable and only after 60,000 km it is necessary to check the ATF level? Firstly, until 2002, according to the manufacturer's regulations, ATF replacement was necessary every 20,000!!!! There were probably reasons for this? It causes healthy bewilderment - what happened to the automatic transmission since 2002 and it suddenly became unserviceable? Secondly, practice shows that the first requests, despite the fact that AL4 goes for 200-250 thousand, already start at 50-60,000 thousand!!!! And regular replacement of ATF allows you to extend the life of the automatic transmission. Although ATF is not a panacea. There are enough factors in this automatic transmission that can affect performance. Thirdly, all recommendations from manufacturers, not only AL4 manufacturers, are designed for ideal operating conditions!!! Russia almost always has extreme operating conditions, which significantly reduces the period for replacing working fluids. If the manufacturer recommends that the unit is not maintenance-free, one can suspect the latter of wanting to make additional profit from the sale of a new unit. Unfortunately, in our opinion, this is a general global trend. And Europe, unfortunately, is ahead of the rest here.

Complete replacement of transmission fluid in automatic transmission

If you have driven more than 60,000 thousand kilometers on your car, then it is time to do a complete change of the used fluid in the Al4 gearbox. This process is done by displacing the old lubricant with a newer one.

Its first steps are no different from the partial change procedure. Only at the end of the process is the connection to the high pressure washer added. However, if there is no such device, then you can call a partner and take a five-liter bottle. Further actions will be as follows:

1. Repeat all the steps described in the paragraphs above up to No. 8 in the “Filling new oil” block.
2. Remove the return hose from the radiator pipe.
3. Ask your partner to start the car engine.
4. Insert the end of the hose into a five-liter bottle.
5. Black waste liquid will flow into it.
6. Wait until the oil changes color to a lighter color.
7. Ask to turn off the engine.
8. Place the hose back onto the fitting.
9. Pour as much oil into the box as was poured into the bottle.
10. Start the car again and drive it for ten kilometers. The new lubricant will get into all automatic transmission components and cover them with a protective film.
11. Stop on a flat surface and check the level, as I taught you in the “Checking the Level” block.

This way you can completely replace the used fluid with fresh one without using a high-pressure apparatus. And the Al4 automatic transmission will be able to work again without errors.

Do not forget to adapt the machine after each oil change. This will help you avoid many of the vagaries of the box, which sometimes occur due to the fault of an unadapted automatic transmission. Because often owners simply don’t give a damn about “taming” the machine, and then complain that it doesn’t listen to them.

Write in the comments if you have already done a complete fluid change. Did it work?

Replacement frequency

According to the Peugeot manufacturer's regulations, oil is filled in the AL4 automatic transmission gearbox for the entire life of the hatchback. But there is one nuance here - the quality of the transmission fluid is determined by a special meter built into the automatic transmission and designed for 6000 hours of operation at a temperature not exceeding 95 degrees. According to these data, the oil does not need to be changed for about 600 thousand km of the vehicle - but provided that the machine does not overheat during operation. If the car drives in the city in start-stop mode, and the driver prefers an aggressive driving style with sharp braking, it is better to update the transmission fluid every 30,000 km.

Oil contamination can be judged by its color and smell, but there is a problem with checking the quality of the lubricant in the AL4 automatic transmission. There is no special probe in the design of the unit! You can assess the condition of the liquid in 2 ways:

partially drain the waste into a container, check the color;

check the meter readings at a technical center using a diagnostic device that connects to the “Measurement of parameters” menu.

As soon as the sensor capacity (32,958 units in total) runs out, the car goes into emergency mode: the “Snow” and “Sport” sensors start flashing on the dashboard. In this case, the automatic transmission is blocked, and third gear is hydraulically engaged.
