During the operation of the car, regular replacement of the transmission fluid of the gearbox is required. This procedure must be carried out regularly, observing the established and recommended deadlines. The Peugeot 308 is equipped with an AL4 transmission, which requires timely maintenance. One of the most important operations to maintain the full functionality of the car is replacing the automatic transmission transmission.
Transmission oil change interval
Many owners of French cars do not know how often it is necessary to change the oil in a Peugeot 308 automatic transmission. The absence of problems with an automatic transmission is not a reason not to service it. Transmission oil performs several functions that are important to ensure the performance of the unit:
- lubrication of parts and mechanisms;
- automatic transmission cooling;
- flushing chips and carbon particles into the pan;
- creating optimal pressure in the box for the functioning of the mechanisms.
According to the manufacturer of the Peugeot 308, the need to change the oil in the automatic transmission arises only after 100 thousand kilometers. Considering that car use in European countries rarely reaches such an odometer mark, and operating conditions are close to ideal, many Europeans have not encountered such a procedure at all.
As for the Peugeot 308 operated in Russia, the situation here is completely different with the quality of roads and climatic conditions. A rare car that has passed the 100 thousand mark has never failed. Therefore, the requirements for vehicle maintenance are different.

To prevent problems with the automatic transmission on the Peugeot 308, the transmission fluid replacement interval should not exceed 50 thousand km.
Why might oil leak?
The following parts often lead to transmission oil leakage from an automatic transmission:
- Wear of seals. Solution: will need to be replaced with new ones;
- Wear of the shaft surface due to insufficient oil level. Solution: add liquid. If necessary, change the shafts;
- Backlash of the input shaft of the box. Solution: tighten or replace;
- There is no seal between the constituent elements. Solution: replace the sealing layer and tighten the components in the form of a crankcase, pan, etc. with the right moment.
Oil leakage from the automatic transmission can also occur for simpler reasons, which can be resolved within 5 minutes:
- The drain nut is not tightened properly. Solution: tighten or replace the O-ring, if necessary.
- The dipstick is not inserted correctly. Solution: change the position of the probe.
- The reverse sensor is not screwed in properly. Solution: tighten it tighter.
Practical advice on choosing oil in a Peugeot 308 automatic transmission
If the question arises of what kind of oil to pour into the Peugeot 308 automatic transmission, it would be wise to find out what exactly was originally filled by the manufacturer. This information is contained in the car manual. It is recommended to use consumables and components from those companies that were used in the Peugeot 308 at the stage of its production.
The manufacturing plant, represented by engineers, selects consumables for its production line based on the best combination of all the necessary properties. This also applies to the transmission. It must ensure uninterrupted operation of the automatic transmission for the stated period.
Original oil
The original oil for the Peugeot 308 automatic transmission is ATF LT 71141 from Mobil. This is a semi-synthetic liquid with high efficiency. The article number for a liter container is 152648. The retail price for 1 liter varies from 600 to 700 rubles, depending on the store. The color of the liquid is red. recommends pouring this particular product into the machine's box.
In addition to Peugeot 308, this fluid is used as an original in automatic transmissions of many European brands, such as Mercedes-Benz and Volkswagen. This indicates the high quality of the lubricant, which is recognized by many manufacturers of modern cars.
Analogs
There is always a replica for any original item. Automatic transmission oil for Peugeot 308 was no exception. There are a large number of brands with similar properties on the transmission fluid market. You can use them, but it is recommended to purchase them from trusted places to avoid purchasing a low-quality product.

Among the numerous brands of oils that can be used in an automatic transmission on a Peugeot 308, the most popular are:
- Febi ATF LT 71141;
- Total Fluide XLD FE;
- Eni Rotra ATF III;
- LIQUI MOLY Top Tec ATF 1200;
- Gulf Multi-Vehicle ATF.
Prices for a liter canister of an analogue vary from 400 to 600 rubles, but the main reason for switching to another type of liquid is not the difference in price, but its availability in the nearest auto parts store.
What oil to fill
At the factory, the AL4 automatic transmission is filled with ATF (Automatic Transmission Fluid) brand LT 71141 in the amount of 5.9 liters. Previously, this oil was quite widely represented by ESSO. Today on the Russian market you can only find Mobil ATF LT 71141 without any problems, although stale ESSO is also found.
Enthusiasts who took the time to study this issue and found out that this ornate coding hides a relatively outdated transmission fluid based on Dexron III.
If we delve deeper into the issue of choosing an ATF fluid, it becomes clear that today there are a lot of oils with similar parameters being produced. The main criteria that determine the operating parameters of transmission oils are viscosity and operating temperature range. And to be more precise, the change in viscosity depending on temperature.
This statement can be considered true for a certain type of transmission fluid. In our case, this is ATF Dexron 3. The additive packages here will be approximately the same.
If you believe more or less authoritative sources on the Internet, transmission fluid based on Dexron III is often interchangeable. It is a transmission marked ATF, and in no case is it a power steering fluid. In this case, additive packages may differ critically.
Here are a few fluids with properties most similar to ATF LT 71141:
- Total ATF Fluide XLD FE;
- MANNOL ATF AG52 Automatic Special;
- Liqui Moly ATF Top Tec 1200.
These are incomplete analogues. And there is almost no information on the Internet about the successful or unsuccessful use of these oils for AL4 boxes.
You can find several fragmentary comments on forums from owners of cars with these boxes that after filling with non-original oil, “the flight is normal.” Therefore, the use of non-original lubricants does not guarantee stable operation of the automatic transmission.
Checking the level
The Peugeot 308 is equipped with gearboxes marked al4. Its peculiarity is the absence of a dipstick for checking the transmission oil level in the automatic transmission. This approach to the design of the unit is explained by the fact that a certain amount of fluid was filled in at the manufacturer, and there is no need to replace it or monitor its condition until the 100 thousand km mark on the odometer is exceeded. And cars in European countries are rarely used for so long.
The Russian “French” were less fortunate - they have every chance to overcome not only the 100 thousand, but also 200 thousand km mark. Despite the absence of a dipstick, there is another way to check the oil level in a Peugeot 308 automatic transmission:
- Start the engine and wait for the cooling fan to start. After this, switch the automatic transmission knob to different modes, then select the parking mode again.
- When the fan turns off, turn off the engine.
- Place a container under the automatic transmission drain plug and unscrew the outer part of the plug.
- The liquid should flow in a thin stream with the formation of bubbles. This is an indicator that the level is normal. You can screw the lid on.
- If the oil flows in a large stream, it means the level has been exceeded. In the opposite situation, the liquid drips in rare drops or does not flow out at all - the level is below normal.

How to change the oil correctly.
To change the oil, you need to go to an overpass. If you don’t have one nearby, you can build it yourself, but it is not recommended. To build it yourself, you will need four foam blocks, or you can replace them with gas blocks, as well as boards. The method for assembling a temporary overpass is very simple. We put gas blocks and lay the board. There are many other correct options for an overpass, you can watch the video on the Internet. It is very important to make sure that the temporary overpass is reliable before driving your favorite car.
Once we are convinced of its reliability, we drive the car onto the overpass. We open the hood, already on the overpass. We take out the dipstick when we pour out the oil. Air will flow through the dipstick hole, which means that the stream from the crankcase will not splash. Then we find the box housing and unscrew the main plug. Before you unscrew, make sure you have somewhere to drain the oil. It is forbidden to drain oil on the ground; in Europe, for spilled oil, a heavy fine is imposed on the culprit. Wait for all the oil to drain. When the oil has drained, tighten the plug on the crankcase and take a funnel and pour new oil through the hole in the dipstick.

Materials for a comprehensive oil change in the Peugeot 308 automatic transmission
Renewing transmission oil on a Peugeot 308 can be done in three ways: partial replacement with draining 3 liters, complete (repeat partial 2-3 times), complete using a special device at a service station. The first two methods can be done independently if you prepare and buy the necessary materials:
| Name | Price in rubles |
| ATP fluid 4 liters or 8 liters | 2000 or 4000 |
| Peugeot 308 automatic transmission filter + pan gasket | 1000 |
| Funnel with extended spout | 150 |
| Container for waste liquid (cut-off five-liter canister or unnecessary basin) | |
| Rags for cleaning surfaces | |
| Tool kit (including torque wrenches) | |
| Total cost of partial (full) replacement | 3150 (5150) |
In addition to the items listed above, to carry out the procedure, it is necessary to take into account the presence of an inspection hole, a lift or an overpass in order to be able to get close to the bottom of the car. It will not be superfluous to take care of additional lighting.
Necessary tools and equipment
In order to replace ATF, you will need the following equipment:
- a funnel with a long spout of small diameter (you can purchase them or make your own using any other funnel and a small tube or hose);
- keys (preferably if there is a set of torque wrenches);
- a container where you will drain the old ATF (minimum volume - about three liters);
- new ATF in the amount of approximately 9 liters for a complete replacement (in total, approximately 7 liters are poured into the Peugeot 208 automatic transmission, but only 3 liters are drained - to achieve the maximum effect, the ATF will have to be changed three times) or 3 for a partial one;
- a set of new gaskets from repair kit No. 144002 (it is recommended to change them when changing the oil);
- clean and dry rags (it is advisable to avoid fabrics that can leave threads and fibers on the surface being wiped).
Do-it-yourself oil change in automatic transmission Peugeot 308
Changing the automatic transmission oil on a Peugeot 308 is a simple task, but it requires care and skills in assembly and disassembly of simple structures. Before starting work, you should change into a thick robe and put on protective gloves, since the fluid in the automatic transmission can burn if it comes into contact with the skin.
Draining old oil
To gain access to the automatic transmission, you need to remove the crankcase protection. Having previously placed an empty container, you can begin to unscrew the outer part of the drain plug. After the oil stops flowing, unscrew the inside of the plug.

There is approximately 7 liters of oil in the Peugeot automatic transmission. A little less than half of the total contents must be drained. The rest remains in the internal mechanisms of the automatic transmission.
When the “transmission” stops flowing and even dripping, you can put the container aside and measure the volume of the used product. The exact same amount must be poured back into the box.
Washing the tray and removing chips
The pan is the bottom of the automatic transmission, where chips, carbon particles and other used components of the unit accumulate. They must be removed and the tray washed. To do this, unscrew the bolts and remove the bottom.
After dismantling, you need to clean the part with gasoline or kerosene. After this, wipe it dry with a piece of lint-free cloth. Place the clean tray aside.
Replacing the filter
Replacing the automatic transmission filter on a Peugeot 308 is a very important point in the oil renewal process. The “transmission” constantly circulates through the filter element, leaving particles of contaminants on it. By replacing it, the automatic transmission will last longer with the new fluid.
After installing the filter, we assemble all the remaining parts of the box. We install a new gasket on the pallet. The bolts are tightened to a certain torque using a torque wrench. Both parts of the drain plug return to their original places.
Filling with new oil
The final stage of changing the oil in an automatic transmission on a Peugeot 308 is filling it. But this stage requires preparation. To get to the automatic transmission hole for filling, you need to do the following:
- lift the hood and remove the air filter;
- disconnect the “plus” terminal on the battery;
- move the fuse box aside;
- disconnect the minus terminal;
- remove the battery;
- Unscrew the automatic transmission filler plug.

After this, you can insert a funnel and carefully fill the “transmission”. At the end of the procedure, perform all the above steps in reverse order.
Replacement instructions
Changing the oil is as follows: 1. Warm up the car and gearbox. This is necessary so that the oil becomes less viscous and acquires sufficient fluidity for quick replacement. You can simply start the engine and let it run for about five to seven minutes, but experts recommend driving 10-12 kilometers in a quiet mode, without frequent switching (the fact is that when the car is idling, the transmission does not warm up well enough). 2. Wait about 5 minutes after running in - the oil should cool down a little (otherwise you risk getting seriously burned). 3. Place the car on a lift or drive it into a pit. 4. Remove the protection from the engine crankcase (to do this you will need to first remove the bumper protection). 5. Go underneath the vehicle and locate the transmission drain plug.
6. Place a previously prepared container for used oil under the drain hole, unscrew the drain plug (this will require a four-sided wrench) and drain the oil. 7. Wait until most of the oil has drained and it stops flowing and starts dripping. After this, unscrew the inner plug and drain the remaining ATF. 8. Screw in the inner and outer plugs. 9. Open the hood, remove the air duct pipe, remove the positive terminal from the battery. Remove the casing from the battery (to do this, you may need to move the fuse block to the side). 10. Disconnect the negative terminal from the battery and remove the battery (you will need a 10mm wrench). 11. Unscrew the gearbox filler plug (probably, access to it may be blocked by the ground wire. To remove it, remove the platform on which the battery is installed). 12. Fill with new oil and install all units back. 13. Start the vehicle and let it idle until the air cooling system turns on or the coolant reaches 60 degrees Celsius. 14. When the fan turns on, shift the transmission into all gears one by one and return to the “park” position. 15. Unscrew the external drain plug under the bottom of the car and wait until the oil begins to drip. Tighten the plug.
Important: in order to “notify” the on-board computer about the replacement time, contact the service center to reset the automatic oil aging counter.
Complete replacement of transmission fluid in automatic transmission
To refresh the entire volume of oil, it is recommended to repeat the partial change 2-3 times at short intervals, for example every week. A 100% oil change in a Peugeot 308 automatic transmission is carried out using special equipment. The installation, under high pressure, forces the used “transmission” through the automatic transmission radiator pipes and fills in fresh one.
This procedure is relevant in the case when the Peugeot 308 was purchased secondhand and its service history is unknown. Unnecessary intervention in the automatic transmission using high pressure can negatively affect the further operation of the unit. And the service itself is expensive.
If the Peugeot 308 has been regularly serviced by one owner and has undergone partial oil changes, then there is no need to resort to hardware replacement. Self-service will save a lot of money and reduce the risk of damaging the box.
What does the manufacturer recommend?
The manufacturer recommends pouring oil into the Peugeot 308 gearbox with LT 71141 approval. The official instructions say nothing about analogues.
As mentioned above, according to the regulations, it is necessary to change the oil in an automatic transmission after 100 thousand kilometers. This means a complete renewal of the fluid in the box.
However, a complete replacement is a rather difficult procedure to carry out independently. Here you will need special equipment that will pump new oil into the system under pressure and at the same time expel the old one. Or disassembling the box.
