The AL4 automatic transmission is one of the most well-known automatic transmissions used in front-wheel drive vehicles. It was developed in 1999 by the French association Peugeot-Citroen. According to Renault classification, this box is called DP0 and in Russia it is best known under this name. Initially, it was installed on the following Renault models: Clio, Symbol, Laguna (front-wheel drive cars with an engine capacity of no more than two liters). Subsequently, AL4 models were acquired by Peugeot (207, 208, 308, 407 and others), and Citroen (C2-C5, Xsara).
The gearbox has 4 main operating modes, as well as a neutral and warm-up mode.
1. Normal operation
- Gear selector position D activates the auto-adaptive shift mode. In this mode, the on-board computer independently selects the modes in which the gears are switched: from the most environmentally friendly to the most dynamic. The choice of a specific program depends on the load on the engine, driving style and road conditions. Mode selection, as a rule, occurs in about 10-15 seconds.
- The position of the gear selector 2 is similar to D, only without the use of III and IV gears. Also in this selector position it is possible to use button 1, which is used for emergency situations and difficult road conditions: when this button is pressed, the gearbox selects only first gear.
- Gear selector position 3 is similar to D, but without IV gear.
2. Sports mode (S button)
- The position of the gearbox selector D includes the most dynamic of the 6 automatic transmission modes.
3. Winter operation mode (button *)
- Selector position D includes the most environmentally friendly mode of operation and does not allow the use of 1st gear, the car starts off from the second. This is implemented in order to prevent slippage on slippery roads.
Operating modes of automatic transmission AL4
4. Sequential operation mode (M button pressed)
- In this case, the driver shifts gears himself. However, upon reaching the minimum threshold value of revolutions for each gear, the automatic transmission AL4 will independently turn on a lower gear, and upon reaching the maximum revolutions, it will shift up.
The design of the AL4 is quite simple, there are no additional “bells and whistles” in it, which slightly increases the operational requirements. It should be treated with care, otherwise the box will not pass the 200,000 kilometers declared in the data sheet - problems will begin as early as 50-60 thousand (Russian operating conditions affect).
- Despite the fact that the box has a warm-up mode, which turns on automatically after starting the engine, the box should be warmed up every time after a long stop. Apply the brake, shift the transmission from park (P) to reverse (R), wait a couple of minutes, put the transmission into drive (D) and wait another two minutes. After that, you can start moving.
- In order to prolong the life of the DP0, immediately after the start of movement, avoid sudden accelerations that use low gears for rapid acceleration.
- Don't let slips. In the cold season, use the winter mode of the box. If this does not help and you are stuck in the snow, do not overload the box, ask someone to push the car. Even if they are random passers-by and they have to pay, remember - repairs cost much more
AL4 design
- If the box turns on the emergency mode on its own (3rd gear is switched on, the inscription PRND appears on the panel), this indicates that the operating pressure has been exceeded. This threatens to overheat the box, faster wear and failure of the clutches, so contact a car service.
- Maintain optimum vehicle temperatures and keep coolant radiators clean.
- Monitor the oil level in the gearbox - for this, visit a car service regularly (the fact is that there is no dipstick to check the oil level in the automatic transmission, so oil level control is possible only in service stations). However, an excessive oil level is easy to notice by oil smudges.
- Every 20,000 kilometers, the oil in the box is changed and its computer diagnostics are performed - do not give in to the manufacturers' assurances that the box is maintenance-free (Important! In the early 2000s, manufacturers stated that the box should be serviced after 20 thousand, after the regulations changed, but the design of the box remained the same). There are only 6.5 liters of oil in the box, but due to the design features, it will not be possible to change it entirely, about 4 liters are replaced.
Features of normal operation of automatic transmission AL4 (DP0)
Normal driving program (self-adaptive parameters)
The AL4 box has several features that are specific to it. If any of the following occurs during the operation of the automatic transmission, there is no reason for concern - these are normal phenomena during the operation of the box, you should not be afraid that something has failed.
- On an unheated box in selector mode D, the transition from I to II gear is carried out with a noticeable push (therefore, as mentioned earlier, the box should be warmed up every time before leaving).
- Hard braking also causes a jerk when switching from II to I, and this does not depend on the degree of warming up. The sharper the braking occurs, the stronger the push will be. "Automatics" do not really like the ragged rhythm of driving.
- When shifting from park (P) to drive (D or R), an increased load on the engine is felt due to the operation of the torque converter.
- When abruptly switching from driving to reverse (and vice versa), a noticeable blow to the box is felt. Moreover, this is typical not only for AL4, but also for many other machines - before switching the direction of movement, a complete stop of the machine is necessary!
- The push when shifting from I to II is not felt in the winter and sport modes of the gearbox. This is quite logical - in winter mode, the car starts from 2nd gear, and in sports mode, switching takes place over three thousand revolutions.
- When the brake is pressed, a click is heard, thus the lock is released.
- When starting the car uphill from the parking mode, it has a small rollback (about 10 centimeters).
AL4 has several work features
Typical malfunctions of the AL4 box
The most well-known malfunction that occurs with this automatic transmission is the failure of the electro-hydraulic valves, which are popularly called "solenoids". These valves are located in the valve body, one of them is responsible for controlling oil pressure, and the second ensures blocking of the torque converter. As a rule, if these valves fail (or do not work correctly), the box switches to emergency mode, third gear is engaged. The main danger of this malfunction is that the torque converter is blocked, the box pump creates high pressure (from 10 atmospheres). Because of this, the box “burns”, or the brake band earring breaks.
Also often there are malfunctions of the automatic transmission pressure sensor. On cars with high mileage, this sensor often starts to give incorrect readings (the pressure measurement error increases by about 100 times), which leads to a pressure adjustment error and incorrect operation of the machine. Another problem that motorists often face is the incorrect operation of the torque converter itself.
Some errors in the operation of the transmission are not related to the box itself at all, but again they lead to an error message about the operation of the gearbox, its switching to emergency mode. Such faults include, for example, brake wiring faults.

conclusions
This is one of the most popular boxes put on French cars. Its design is simple, but requires quite careful observance of operational rules. There are some nuances, for example, the box is prone to overheating. However, there are obvious advantages - the planetary mechanism of the box is exceptionally reliable, the electric control unit also works fine. Should I buy a car with such a box? Many motorists consider it not reliable enough for Russian operating conditions. If you carefully monitor the condition of your car, like a quiet ride and take care of the transmission - AL4 will not give you a reason to worry. If you prefer a “ragged” driving rhythm, fast acceleration with frequent switching, then it is better to choose a more suitable option.
Equipped with automatic transmission models DP0 / AL4. The average service life of this transmission before overhaul is 200 thousand km. run. Automatic transmission solenoids, which, in fact, are consumable items inside the gearbox, must be changed for the first time on a run of 70 thousand km. Usually, two solenoids are changed at once, the most loaded and therefore most often failing.
If you regularly change the fluid in the automatic transmission (every 30-50 thousand km), do not operate the box with overload (slipping, driving with a trailer, driving at top speeds for a long time, etc.), then the DP0 box can last up to 250 t. km.
Common signs of problems in the Peugeot automatic transmission:
- extraneous noise
- Vibration
- aftershocks
- blows
- Oil leakage in automatic transmission
- Dark oil with a specific odor
All of these symptoms may indicate the need for prevention or repair of automatic transmission.
Problems specific to automatic transmission DP0
- The automatic transmission enters emergency mode (most often, diagnostics will reveal a pressure error)
- Sensitive "jerks" from 1st to 2nd gear. Manifested in "traffic jams" at low gas
- Automatic transmission does not switch to 2, 3, 4 gears.
- The vehicle does not move in R and D mode.
- "Overshoot" of the internal combustion engine speed on the tachometer without changing the speed of the car (loss of traction). Mostly occurs when shifting gears.
Peugeot vehicles with an engine capacity of more than two liters
Such Peugeots are equipped with an automatic transmission of the TF80SC model. This is a Japanese gearbox manufactured by the AISIN concern. According to statistics, the average service life before overhaul of this automatic transmission, with regular maintenance and a calm driving style, is approximately 180-220 thousand km. run. In the best case, this figure can even exceed 280 tons. Km.
However, if you do not regularly change the fluid in the automatic transmission, then a major overhaul of the unit is possible already at a car mileage of 120-150 tons. Km. Although this automatic transmission for Peugeot is quite reliable, one of its specific problems is the “fear” of overheating and criticality to the quality of the liquid.
Complaints to the execution of the automatic transmission can be quickly and relatively inexpensive (especially when compared with a major overhaul) eliminated if you contact a specialized service after the first symptoms.
Well-known car manufacturers such as Citroen and Peugeot install the popular AL4 automatic transmission on most of their models. When developing this unit, the engineers set themselves the goal - it should be economical and simple. As a result, the AL4 turned out to be the car's weak link.
Signs that you need automatic box repair AL4 there are suspicious shocks or even shocks in the automatic transmission when switching from one gear to another. Having “caught” such a malfunction, we can easily fix it by replacing the valve body solenoids.
Overheating is the most "favorite" problem of French automatic transmissions. By contacting our car service on time, it will be possible to “cure” AL4 relatively inexpensively, since the prices for repairing automatic transmission AL4 (AL4) in Moscow are still “democratic”.
Such a “disease” as a spontaneous change of regimes is the most neglected for AL4. To solve this problem, a major overhaul is needed.

Since the French cars came to our market, the popularity of technology has been constantly growing. Automotive giants PSA Group (Peugeot Citroen) and Renault Group supply products to 200 countries, including our region.
Today, a trend has been established for buying front-wheel drive cars equipped with power plants up to two liters in volume, and. French manufacturers needed one. The desired characteristics of the designed gearbox, small dimensions and weight, but not at the expense of reliability and compatibility with popular power plants.
After the work done, with the joint efforts of the designers of PSA and Renault, an automatic, equipped with electronic control, marked AL4, was launched on the market. Today, the number of produced gearboxes of the model exceeds the output of similar products for cars with front-wheel drive and an engine with a volume of 1.4 - 2.0 liters.

The transmission was calculated for use on cars with front-wheel drive, paired with units with a volume of 1.4 to 2.0 liters. Some modifications of automatic transmissions differ in housing, drive gears and settings. The automatic transmission is simple and reliable, the design does not provide for unnecessary parts and mechanisms. The margin of safety incorporated in the calculations is able to allow the mechanism to withstand an impulse with a force of up to 210 Nm, however, to increase the resource, these indicators are limited by the settings.
Brief technical characteristics of the automatic transmission AL4 (DP0) are presented in the table:

The main advantage, transmissions, reasonable cost, this allowed the machine to become popular among cars with a small engine size. The gearbox received positive reviews and popularity, which later made it possible to take the automatic transmission as the basis for an improved modification. Together with Siemens, an improved AL4 model was released, which was equipped with the Porsche Tiptronic System device, while the mechanics of the machine did not change
Switching modes, box rocker AL4
The gear box is located in the central part of the cabin. Purpose, selection of the desired mode, by acting on a special contactor device and a spool that switches hydraulic modes. The rocker is equipped with six positions, switching takes place by moving along the slot of the selector panel stream.
Gear selector positions:
- P - parking mode, the transmission is blocked, the start of the power plant is possible;
- R - reverse mode, when turned on, the reverse lights light up at the same time;
- N - neutral mode, the launch of the power plant is possible;
- D - automatic adaptation mode "Drive", shifting forward gears from first to fourth and vice versa;
- 3 - Automatic mode, limited to three gears (1-2-3 and vice versa);
- 2 - Automatic mode, limited to two gears (1-2 and vice versa);
Modes "2" and "3" are automatically limited because they are controlled by the computer.
Important! To unlock the gear lever from the "P" position, you must turn on the ignition and press the brake pedal, the "Shift-Lock" function.
The gearbox is equipped with a special mechanical protection mechanism that prevents damage to the transmission parts in the event of an incorrect transition from one position of the backstage to another. The transition from the following provisions without fail occurs through the provisions:
- From "P" to "R";
- From "R" to "P";
- From "N" to "R";
- From "D" to "N";
- From "3" to "2".
In order to satisfy the needs of the driver in driving with the use of additional high-speed modes, a software selector is structurally provided. The mechanism is equipped with three keys and is located on the side of the wings.
Gearshift rocker paired with program selector:
Selector programs:
- Standard program (none of the keys are pressed, the rocker in the "D" position):
The program is considered the main one, when using it, the computer analyzes the driving style and adapts it to road conditions and vehicle load. The main goal is to achieve lower fuel consumption and optimally distribute the effort;
- Program "Sport" (pressed key "S", rocker in position "D"):
Using the program involves automatic gear shifting, but at the same time, the computer prefers a sporty style and does not pay attention to the amount of fuel consumed;
- Program "Snow" (key pressed "*", slide in position "D"):
Using the program, the computer adapts to the conditions of the slippery road surface. Driving begins by using second or third gear with infrequent downshifts. This mode allows you to reduce the wear of the gearbox mechanisms and increase its service life;
- Mode of forced limitation of the first gear (pressed the key "1", the rocker in position "2"):
The gearbox will only work in first gear.
Features of the program "Shift Lock":
When moving the backstage to the "P" position without depressing the brake pedal, the automatic transmission selector will be blocked. When the vehicle is stationary and the engine speed exceeds 2000 rpm, moving the lever to the "D" position does not shift gears.
Important! When the ignition is turned off and then turned on, the computer automatically switches to the standard program.
Indication on the information board:
During the operation of the box, the illuminated software panel informs the driver:
- Information about the position of the backstage lever;
- Information about the program used;
- Information about the transition to the backup mode.
Indication on the instrument panel:
AL4 box malfunctions
Despite the positive reviews and popularity of the transmission, the AL4 automatic transmission has vulnerabilities. The problems observed in the mechanism, as a rule, occur in most boxes of this type.
- A thud and jolts at start. Symptoms occur when you start moving without first warming up the box. The reason for this manifestation lies in the difference in oil pressure indicators. The data used by the computer to calculate the desired modes do not match the actual characteristics. The reason is a malfunction of the pressure regulator in the valve plate. In addition, a possible reason is an insufficient level of transmission fluid, and a violation of the tightening torques of the bolts that secure the valve body.
To eliminate the defect, they check if oil is leaking in the AL4 automatic transmission, analyze the condition of the heat exchanger, replace the lubricant, remove the hydraulic unit and change the valves. If the mileage of the box is over 100,000 km, a full service will be required, including dismantling, disassembly, flushing, of the valve plate. In the future, the stove will need to be adjusted and adjusted. After completion of work, reconfigure and clean the on-board computer of the car.
Pressure Regulator #144431:
- The gears are switched with a delay. The breakdown is accompanied by jamming of the backstage lever in the “P” position. Sometimes on the contrary, the link is switched from a position without pressure on the brake pedal. As a rule, the culprit of non-standard behavior is a malfunction of the brake sensor.
To fix the problem, change the limit switch, check and change the damaged electrical harness of the switch.
Brake Pedal Limit Switch:
- Knocking and jolts when the car is moving, flashing an error message. The behavior manifests itself in moving vehicles, both a warm and cold gearbox fails. Often there is an increase in the number of revolutions, although the gear shift does not occur, the car's clutch seems to be slipping.
The reason lies in the breakdown of the valve that controls the blocking of the hydraulic transformer, as well as in the hydraulic valve, which is responsible for the correct pressure in the hydraulic unit.
Important! With such symptoms, stop using the car. Further driving on a faulty vehicle is fraught with a break in the brake of the hydraulic transformer.
To fix the problem, the automatic transmission is checked for transmission fluid leaks, the heat exchanger is checked, the hydraulic unit is dismantled with the replacement of valves. In addition, it is necessary to perform a complete replacement in the transmission. Strong wear and mileage of the box over 100,000 km indicates the advisability of replacing the hydraulic unit with a new one. The work is accompanied by the subsequent loading of a new program into the on-board computer of the car.
- Switching the backstage is accompanied by the absence of the indicator of the selected mode on the information board of the car. Symptoms are observed mainly when the backstage is switched from the parking mode to the reverse mode, as well as when the backstage is switched from the standard mode to the neutral mode.
The cause of the AL4 automatic transmission malfunction lies in the breakdown of the gearbox switch. In addition, this behavior is typical when the device settings fail or the sector responsible for selecting the gears of the AL4 box fails. Also a possible reason is the selector cable, which is loosely fixed in the bracket and constantly pops out of it.
A switch malfunction is possible due to moisture ingress, factory defects, or severe wear. Elimination comes down to replacing or adjusting the above listed parts.
The described problems are often encountered when operating the AL4 / DP0 gearbox. Malfunctions are characterized by an implicit manifestation, they can be observed at any time during the use of the box, regardless of the mileage.

Changing the transmission fluid in automatic transmission AL4
The Al4 variable gearbox is a reliable and trouble-free unit, provided that the mechanism is serviced in a timely manner. The transmission is demanding on the quality of the fluid and its level, so the oil change in the AL4 automatic transmission should be carried out regularly in compliance with all necessary rules and regulations.
Every 30,000 km it is necessary to check the level of transmission fluid in the box. If there are small smudges in the form of spots on the product, then the check is carried out daily so as not to miss the moment of large oil losses. Automatic transmission oil AL4 is controlled by a metal plug, which is provided structurally. The peculiarity of the plug is that it is composite and at the same time serves both to control the liquid level and to drain the oil from the box.
Level control is carried out as follows:
- Install the car on a lift, pre-heating the transmission fluid in the box to operating temperature;
- Do not turn off the engine until the forced cooling fan turns on;
- Translate the gear selector in turn to all modes, followed by transfer to the parking mode "P";
- Turn off the engine;
- Unscrew the control plug, having previously installed a container for draining mining;
- Check for the appearance of small streaks of transmission fluid;
Important! Oil flows in a stream - excess of the liquid norm; small drops - the fluid rate is too low, there is no oil - underfilling of the working fluid. All these indicators have a negative impact on the transmission and require immediate replacement of the lubricant and bringing its level to normal.
- Screw on the control plug.
In any case, in the AL4 automatic transmission, the oil is changed once every 40,000-60,000 km, depending on the operating conditions and the load on the box. The oil used for filling into the transmission must meet the Dexron-III level, as a rule, it is ATF LT 71141 ESSO or Mobil. A complete replacement will require about seven liters of fluid, a partial replacement requires four liters.
ATA LT 71141:
It is better to carry out a complete replacement on special stands that will pump out all the lubricant from the system.
For self-replacement you will need:
Set KFS 959 filter, gasket
Steps for replacing the transmission fluid of the AL4 box:
We drain the waste liquid:
- We warm up to operating temperature;
- We unscrew the control plug of the gearbox, after substituting the prepared container;
- After draining part of the fluid from the gearbox, unscrew the main plug and drain all the fluid;
- We dismantle the gearbox pan, wash it from impurities using washing liquid;
- We change the filter element, put the pan with a new gasket in place;
- We change the sealing ring of the plug, tighten the plug with a force of 2.5 Nm.
Filling with new transmission fluid:
- We unscrew the plug of the gearbox to fill the liquid;
- Using a filler funnel, fill the required amount of oil;
- We install the plug in place, a force of 3.2 Nm.
Liquid filling control, pumping:
- We start the power plant;
- We warm up to a temperature of 60 ° C;
- We translate the gear shift gate into possible modes, return to the parking mode "P";
- We control the level of the filled fluid, top up if necessary, or drain the excess.
- We close the control plug of the gearbox, a force of 2.5 Nm.
After replacing the transmission fluid, it is necessary to periodically check the level and possible leakage of fluid from the gearbox. When detected, it is necessary to urgently fix the problem, otherwise serious damage cannot be avoided.
Careful care of your gearbox, a calm and smooth ride, careful handling of the transmission, oil and filter element changes on time will allow you to fully enjoy the benefits of the AL4 automatic transmission.
Peugeot automatic transmission repair is our profile. What is the resource of the Peugeot automatic transmission and how to extend its life?
First, let's say a few words about the AL-4 automatic transmission itself.
The adaptive automatic transmission AL4 with the Porsche Tiptronic System is installed on most Peugeot and Citroen cars, and is produced in France in partnership with PSA and Siemens. The box is quite old, however, in 2004 it was slightly modernized and some “childhood diseases” were eliminated.
The first, most common automatic transmissions AL4, installed on the Peugeot 206, 307.406, 407, Citroen Xantia, Xara, C4, C5 of the first years of production were especially unreliable. On fresh cars, the characteristic "diseases" of AL4 are much less common, but only under conditions of proper operation and frequent oil changes.

Try to avoid wheel spin on slippery roads;
Do not switch the gear position selector lever unnecessarily;
Carry out periodic (every 30 thousand km) partial or complete (in case of disassembly of the box) automatic transmission oil change Peugeot - Citroen (LT71141). This point is especially important, because official dealers carry out such a procedure only at the request of the client, because the cunning manufacturer does not recommend changing the oil in the automatic gearbox at all.
