Renault Laguna is the mid-size flagship car of the Renault company, produced since 1999. In 2007, sales of the “third” Laguna began. This generation was the last in the history of the family. This generation was designed on the Nissan Teana platform of that time. The car received three body types - hatchback, station wagon and two-door coupe. Engines are 1.6 and 2.0 liter petrol, as well as 2.0 turbo and 3.5 liter V6. The most powerful engines were installed under the hood of the coupe, which competed with the Volkswagen Passat SS. In 2010, the car was modernized, and in 2015 it became known that the production of the third generation Renault Laguna had been completed.
Changing automatic transmission oil AL4/DP0/(DP2,DP8)
The most common automatic transmission in all French cars is the DP0 gearbox for Renault, it is also the AL4 in Peugeot/Citroen. In the new Renault DP0 was modified into DP2 and DP8, but the oil change procedure, as well as the need for regular oil changes, have not changed. And many owners of French cars are wondering whether to change the oil in their automatic transmission. After all, the manufacturer claims that oil is filled for the entire service life of this unit. In theory, while the car is new, all joints and assemblies have factory clearances, the bushings are not worn out, the oil is cleaned quite reliably by the filter... In practice, taking into account the operating conditions and urban driving conditions (constant stop-and-go), a chain reaction of wear often occurs. Thus, the older the unit, the greater the wear of the hardware components and the faster the oil becomes contaminated. It is no secret that this is accompanied by emergency overheating and overloads.
All transmissions with a heat exchanger in their design operate at temperatures close to critical. This box is no exception, and also has a heat exchanger for cooling the oil. In used cars, the heat exchanger gets clogged/clogged, which leads to constant overheating, which is why the valve body suffers. At the same time, there is a strainer in the box, but it is changed only when removing and disassembling the machine; replacing it along with changing the oil or replacing valve body solenoids will not work.
We advise you not to test the box for strength, and to completely change the automatic transmission oil every 40-50 thousand km or partially every 20-25 thousand km. It also makes sense to install an additional cooling radiator along with a thermostat instead of a heat exchanger.
The oil this box is designed for is Dexron-III quality. The recommended Citroen/Peugeot fluid is Mobil LT 71141 (semi-synthetic) and works well in this box. The recommended fluid for Renault is Elf D3 Syn (Synthetic). There is also a synthetic fluid option from Total - Fluide XLD FE .
Service life and malfunctions of automatic transmission DP2 and DP0
The fault was with a small heat exchanger, which in hot weather simply could not maintain the temperature in the range of 75-90 degrees Celsius . Also, pressure modulation valves often fail. The cause of the problem is not new and why manufacturers do not want to solve it initially from the factory is not known.
Not only the “French” suffer from elevated temperatures: Aisin installed on VW Group models, CVTs on cars of the Renault-Nissan-Mitsubishi are also susceptible to overheating. The solution is obvious - installing an automatic transmission cooling radiator; ready-made additional cooling kits are already sold at a cost of 12,000 rubles .
DP Series Automatic Transmission Cooling Kit
The second option to avoid transmission repairs is to change the oil at an interval of 20,000 km . The box was designed as maintenance-free - oil was filled for the entire service life. Maintenance-free in the literal sense of the word, to change the filter you need to remove the box and halve it.
DP2 disassembled
Replacement can be made either partial or complete. A complete oil change is carried out by repeatedly draining and adding new oil; this procedure will need to be performed 5 to 7 times (more than 15 liters ).
Summing up the French transmission
Although automatic transmissions DP2 and DP0 do not shine with reliability (it can last around 100 thousand km , and if you follow the recommendations, you can significantly increase this mileage), they can give you a head start in the cost of repairs.
Since the box is massive, spare parts for it can be found easily and at reasonable prices, and repairs can be carried out in almost every garage. Automatic transmissions DP0, DP2 and DP8 boxes of the same series, in addition to them can be attributed automatic transmissions Peugeot-Citroen At\T 8 and AL6. The boxes do not shine with reliability, they are very sensitive to oil changes and overheating

Is it necessary to change the oil in an automatic transmission?
Partial or complete automatic transmission oil change?
Partial replacement (ATF update) is carried out without flushing the automatic transmission. To carry out such work, on average, 4-5 liters and half an hour of time are required. The new oil is mixed with the old, and the operation of the box becomes smoother. Many car enthusiasts believe that it is better to exclusively replace the ATF completely, with flushing the system and displacing the old fluid. We do not pursue the goal of earning as much as possible from our clients, but we warn about possible problems and recommend in some cases ONLY partial replacement.
In what cases is a complete ATF replacement carried out?
All of the above problems do not concern car owners who every 50,000-60,000 km. carried out a routine oil change in the transmission. In this case, a complete oil change in the automatic transmission allows the box to serve faithfully and increases its service life by 150-200%.

What kind of automatic transmissions are used in Renault Logan?
Automatic transmission AL4
Renault Logan aggregates automatic transmission AL4 (aka DP0) and DP2. And for each model, the official dealer advises using its own brand of gear oil. But more on that a little later.
Interestingly, replacing the transmission fluid in Renault Logan can be done partially or completely.
For the first case, at least 4 liters of liquid will be required. The second contains 7 liters and, in addition, special tools.
Service station experts recommend performing both procedures, but at different times. For example, a partial replacement in an automatic gearbox should be performed every 40 thousand km, and a complete replacement every 80 thousand km . Please note that opinions may differ. Therefore, the best option would be to consult with a master whose professionalism is beyond doubt.
Do-it-yourself complete and partial oil change in the Renault Megane II automatic transmission
The Renault Megane 2 automatic transmission needs regular oil changes. Without this procedure, you will not drive the vehicle for a long time, because the automatic transmission will go into emergency mode after eighty thousand km. And it will be good luck if the machine does not require major repairs.
Therefore, I advise you to listen to further instructions and not to follow the lead of manufacturers, who have begun to often use the words: “an automatic machine in which the lubricant can not be changed until the service life of the box is over.”
Write in the comments, have you already changed the lubricant in the Megane II automatic transmission?
Transmission oil change interval
Renault Megane II, Citroen or Peugeot are equipped with French AL4 gearboxes, called DP 0 in Russia. Automatic transmissions on cars are demanding of clean oil. This especially applies to old machines that are reaching the end of their service life and are almost ready for major repairs.
The replacement interval for the Renault Megane II automatic transmission is as follows:
Attention! Check the lubricant level after driving ten thousand kilometers. Automatic machines for Renault Megane II do not like oil starvation. If you do not add transmission fluid in time, then rapid wear of metal parts will begin, the products of which will lead to clogging of the filter and all systems.
To do a complete transmission fluid change, you will need to call a partner. Therefore, think about this issue in advance if you do not have a high-pressure apparatus or take the car to a service center. Experienced mechanics will replace the grease within 3 hours.
Along with testing, do not forget to change the components of the Renault Megane II gearbox. And after 150,000 kilometers, be sure to clean the valve body and cooling system. By cleaning the hydraulic plates, you will avoid overheating and early emergency modes in the automatic transmission.
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.

DIY Renault Megane automatic transmission repair
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:
- Repeat all the steps described in the paragraphs above up to No. 8 in the “Filling new oil” block.
- Remove the return hose from the radiator pipe.
- Ask your partner to start the car engine.
- Insert the end of the hose into a five-liter bottle.
- Black waste liquid will flow into it.
- Wait until the oil changes color to a lighter color.
- Ask to turn off the engine.
- Place the hose back onto the fitting.
- Pour as much oil into the box as was poured into the bottle.
- 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.
- 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.

Practical advice on choosing oil in the Renault Megane II automatic transmission
When changing the working hours, do not pour ordinary Chinese mixtures into the machine. They do not have the viscosity necessary to form a protective film on metal parts. Use only original fluid.
The same synthetics are used for Peugeot, Renault Megane II and Citroen cars. We will talk further about what kind of oil this is and in what quantities to fill it. In the meantime, answer in the comments what kind of transmission fluid do you usually use?
Original oil
The original oil in the Renault Megane II automatic transmission is Elf Renaultmatic D3 Syn (catalog number 194754). Synthetic fluid based on Dexron III is poured into the automatic transmission from the manufacturer. I do not recommend mixing it with analogues. Therefore, if you do not have this liquid in your city, and you are going to fill in a lubricant similar to the Dexron III standard, then first of all you need to flush the system and make a complete replacement of the drain.
Analogs
Analogs that are poured into the Renault Megane II automatic transmission include the following transmission fluids:
Write in the comments what analogs you used?
The best motor oil. does it exist?
- The driver drives aggressively, starts and brakes abruptly, allows active maneuvers and lane changes
- The car is used mainly in the city, in “start-stop” mode, when there are a lot of traffic lights and traffic jams. In such conditions, the transmission operates under load due to frequent shifts. Over time, the box overheats and accelerated oil wear is possible.
- Regular off-road use (rocks, snow, gravel, sand), in rainy and slushy weather
- Towing heavy loads, driving at maximum speeds, and other severe conditions, including extremely hot or cold temperatures.
Signs of untimely oil change in automatic transmission:
- The oil pressure in the line decreases, caused by insufficient oil level in the automatic transmission, as well as damage to the oil pump relief valve. In addition, there is a high probability of dirt accumulation in the solenoids or valve body.
- Slipping when changing gears, including when moving uphill in last gear
- The car cannot move, despite the gearbox being fully operational.
Checking the level
This automatic transmission does not have a dipstick for checking the lubricant level. Therefore, you will have to work hard to find out how much lubricant is left in the machine. To do this, take the following steps:
Pay attention to the color and impurities that may be in the transmission fluid. The presence of chips in the lubricant indicates that it is time to change the steel discs and clutches, as they are out of order.
If the color of the lubricant is black and all sorts of impurities are present, then you should replace the waste in the Renault Megane II automatic transmission with a fresh original Elf Renomatic 3 D.
