Repair warranty
A high-quality repair of a Peugeot 307 automatic transmission should include initial diagnostics (connecting a scanner and a test drive), removing the transmission from the car, disassembling, reassembling, repairing the valve body, torque converter and subsequent testing on the car. With this approach, complete restoration of the automatic transmission takes 2-3 days
.
If you are promised to “fix the machine in a day,” feel free to look for another service. provide a guarantee of 12 months or 30,000 km
for the work performed , provided that all the recommendations of the master are followed. In other words, if, when repairing an automatic transmission, in order to save money, all recommended work was not performed, we cannot provide a guarantee for such a transmission. In the automatic transmission mechanism, everything is interconnected - one malfunction causes failures in other components, and in this case it will not be possible to get rid of it with partial repairs.
“Childhood diseases” automatic transmission Peugeot 307 AL4
Malfunctions of Peugeot 307 automatic transmissions can be divided into two parts - problems with hydraulics
and
problems with hardware
.
Malfunctions associated with clogging of valve body channels, failure of solenoids and pressure modulation solenoid valves can occur as early as 70,000-80,000 km
.
Symptoms of the problem are jerks/shocks when shifting and driving under load on a warm car. The main reason for this is overheating of the automatic transmission due to the lack of a radiator and operation on dirty oil with wear products of the friction discs. Mechanical wear appears much later (on average after 130,000 km
) and the symptoms resemble problems with the valve body, with only one difference - shocks/kicks are also present on a “cold” box.
In terms of hydraulics, the main problem is the failure of the pressure modulation solenoid valves in the valve body
.
The second common malfunction is insufficient line pressure in the circuit due to wear of the pump's bronze bushings. During the repair, a new pump cover bushing from the American brand Sonnax 144034-SX
(57.2×54.8×13.7) and a pump stator bushing Sonnax 144037-SX (29x26x16) are installed. In the design of the Peugeot 307 automatic transmission, bushings also play the role of seals. When they wear out, the pressure in the clutch packs drops significantly, and the EPC solenoid tries to compensate for it by opening the channel to its full cross-section. This increases the load on the oil pump and the solenoid valve itself.
Due to insufficient pressure, the clutches begin to slip and “burn”, the oil quickly becomes clogged and clogs the channels of the hydraulic plate.
and damages the solenoids. By 150,000 km, the brake bands wear out and the working surface of the drum wears out. The lining layer becomes thinner, and the tape begins to leave rivet grooves on the drum. When overhauling a Peugeot 307 automatic transmission, the F2 and F3 tapes are replaced with the original - Borg Warner 144020-BW. Often, along with the tape, it is necessary to change the drum of the clutch pack F3 - 144550A-EM.
Peugeot 307 automatic transmission valve body repair
Signs of a faulty Peugeot 307 valve body:
Shocks when switching;
The transmission goes into emergency mode; The “snowflake” indicator light came on on the dashboard;
Sluggish response to pressing the gas pedal;
The box “freezes” in one gear;
Impact when starting to move.
Before starting any work, it is mandatory to carry out computer diagnostics of the Peugeot 307 automatic transmission using a PSA DiagBox dealer scanner. If the low pressure error is on, you will most likely be able to get away with replacing the EPC and TCC valves.
Two modifications of the valve body were installed on the AL4 transmission
– 2570E2 and 2570E3.
The valve body is responsible for shifting gears by changing the ATF fluid supply pressure. The control valves become clogged with friction wear products
, and the oil pressure deviates from the factory parameters. As a result, the clutch packs begin to slip and the transmission overheats. There are 8 solenoids located in the valve body housing. In simple terms, a solenoid is a valve-regulator that, at the request of the “brains,” opens and closes the channels of the hydraulic plate to control the flow of ATF fluid. Usually two solenoids are replaced at once (EPC - linear pressure and TCC - responsible for locking the torque converter). There are two replacement options - the original and Borg Warner (USA). Most often the EPC solenoid fails, especially if the box has problems with bronze bushings and Teflon seals. If the valve responsible for locking the torque converter malfunctions, the oil quickly becomes contaminated with friction dust. The six EVS solenoids in the hydraulic plate rarely require replacement.
Replacement of solenoid valves
(Renault 7701208174 or Borg Warner 144431A-BW) are usually combined with flushing the hydraulic plate channels and replacing the working fluid. The cost of replacing valves and flushing the DP0/DP2/DP8 valve body along with new oil (4 liters Mobil ATF LT 71141) is RUB 14,500. The operation time is 5 hours.
What kind of oil to fill
There are certain markings, tolerances and viscosity classes from which the oil parameters are compiled. So, we will highlight the most suitable brands and types of lubricants, along with suitable parameters developed specifically for modern cars, such as the Peugeot 308:
- Mobile ATF LT 71141
- Liqui Moly Top Tec ATF 1200
- Esso ATF LT 71141
- Total LT 141173
Also among high-quality analogues one can highlight products from the brands ZIC, Castrol, Elf, Lukoil and other well-known companies.
How often do you need to change the oil in a Peugeot 307 automatic transmission?
In the Peugeot 307 automatic transmission, ATF oil, in addition to its lubricating function, also transmits torque from the engine to the transmission
.
During operation, the transmission generates a large amount of heat, and the oil heats up above 100 degrees Celsius. If the temperature exceeds the critical level of 110 degrees
, accelerated wear of all components begins. Even with a single overheat, the liquid loses most of its characteristics.
According to PSA regulations, it is recommended to change the oil every 60,000 km
, but when operating in harsh conditions, we recommend reducing the interval to 45,000 km. Unfavorable factors include aggressive driving style, off-road driving, deep snow/sand, maximum vehicle load and towing a trailer.
For oil aging
First of all, it is affected by the ingress of wear products from the friction linings and the adhesive layer into the liquid. Small particles are mechanical debris that clogs the filter and channels. The second enemy of oil is the process of oxidation and the development of a package of additives that prevent foaming. Thirdly, high temperature has a detrimental effect on the liquid. Modern Peugeot 307 automatic transmissions use a partial locking mode of the torque converter, when the clutch constantly slips in an oil bath. Wear of the friction layer leads to the appearance of fine abrasive dust in the oil, which enters the valve body and damages the linear solenoids.
Full factory fill volume AL4
- 8 liters.
When replacing using the drain-fill method, about half the volume remains in the filter, valve body and torque converter. To perform a hardware oil change
in a Peugeot 307 automatic transmission, you need to install an adapter instead of the standard heat exchanger (not possible on all models).
Since there is no tray on the AL4, the front cover of the valve body is removed to clean the magnets
. Some modifications may not have magnets - in this case, we recommend installing them. If you want to replace the fluid in the Peugeot 307 automatic transmission with the highest quality possible, we recommend carrying out the “drain-fill” procedure twice with a short interval. If the gearbox is faulty, changing the oil will not help.
Changing the oil in the Peugeot 307 gearbox
The procedure for checking the required level of transmission fluid for an automatic transmission, abbreviated as TM, is carried out according to its own principle. To do this, you need to purchase half a liter class=”aligncenter” width=”960″ height=”720″[/img]
- It is necessary to drive the car into the inspection hole. The automatic transmission selector must be installed in the position indicated by the letter “P”. The handbrake must never be in the raised position.
- It is necessary to connect the diagnostic device, while selecting the option that determines the measurement of parameters on the device display.
- The hood of the vehicle is opened and the filler cap is unscrewed.
- Using a special syringe, half a liter of TM is poured into the automatic transmission.
- The engine starts. After which it needs to be warmed up for some time. When checking, the engine operating temperature must be in the range from 59 minimum to 68 maximum degrees. With the engine running, unscrew the plug that is installed to check the TM.
- It is very important to remember: if the transmission fluid flows out first in a thin stream and then just drips, then its level is normal. In this case, the readings on the meter are updated, which determines the wear of the transmission fluid using diagnostic tools.
If the TM drips at first, and then stops flowing altogether, then it is necessary to add 0.5 liters to the automatic transmission. TM.
Peugeot 307 automatic transmission repair due to overheating
The main culprit of all problems with Peugeot 307 automatic transmissions is overheating. The manufacturer decided to save money and left the AL4 without a radiator. The transmission is cooled only by the air flow
passing through the main radiator block and the electric fan. We advise you to keep them clean and wash them every two years. All owners are strongly recommended to install an additional radiator along with a thermostat. A thermostat is necessary to regulate the flow of oil to the radiator depending on its temperature.
First of all, the properties of the oil itself are lost due to high temperature.
. It is designed to operate up to 110-120 degrees, so if it gets too hot, it simply “burns.” This is evidenced by the black color of the waste fluid and the specific burning smell from the “eaten” clutches. Secondly, the internal electrical wiring (wiring to the solenoids and valve body valves) may melt.
Thirdly, overheating leads to breakdown of the friction discs, which are responsible for the clutch between gears. According to a signal from the electronics, at the right moment, under the influence of pressure, they are compressed and stop the desired gear, and then release it again. Wear products
contained in overheated oil
clog the filter
. This causes a drop in pressure in the system, which is no longer able to compress the clutches (they begin to slip).
All these malfunctions can be avoided if you install an additional radiator for the Peugeot 307 automatic transmission
.
Often, many people don’t even think that non-standard cooling still needs to be chosen correctly. Usually the rule that works here is plus 30% of the area of the standard radiator, but you can also select it based on temperature by sticking a special temperature sensor
.
Experienced Orbita service technicians will help you choose additional cooling for your car and driving style. For passenger cars with engines up to 2 liters
, which are operated in a gentle mode, the smallest tubular model is usually sufficient. For older cars that often tow a trailer or drive off-road, we recommend using a six-row modification.
When to change
To start choosing, or even changing the oil, you first need to make sure that the fluid really needs to be replaced, otherwise problems will arise with the reliability of the transmission. The Peugeot 308 is equipped with a fairly reliable AL-4 gearbox, which is distinguished by good clarity of switching, as well as the absence of jerks and lags when switching to a lower or higher speed. But it is important to understand that such excellent qualities are provided not only by the unique design of the gearbox, but also by the beneficial properties of the oil. Over time, they lose their properties, and in this case the question arises - when will this happen. There are certain regulations on this matter established by the manufacturer. According to official data, it is recommended to change the oil in the Peugeot 308 automatic transmission every 100 thousand kilometers. It must be said right away that this indicator is not suitable for difficult climatic conditions in Russia, and is calculated rather for European countries with favorable weather realities. In this regard, many experienced owners, as well as local Peugeot dealerships, advise replacing them every 50 thousand kilometers.

Engine and transmission oils for Peugeot 308
The Peugeot 308 hatchback was first introduced in 2007 as a replacement for the 307 model. The car inherited the PSA PF2 platform from its predecessor, but received a new appearance and significant technical modernization. The first generation 308, produced until 2013, was equipped with Prince four-cylinder petrol engines, developed jointly with BMW, with a volume of 1.4 and 1.6 liters, the latter had a turbocharged version, as well as 1.6 or 2.0 liter turbodiesels. Depending on the configuration, cars were equipped with a 5- or 6-speed manual transmission, a 4- or 6-speed automatic transmission, or a 6-speed robotic gearbox. In addition to the 3- and 5-door hatchback, the Peugeot 308 was also produced in station wagon and convertible bodies. Production of the second generation model started in 2013, it is built on the new EMP2 platform. The updated 308 has only 5-door hatchback and station wagon versions and is equipped with 1.2 or 1.6 liter petrol engines, mostly turbocharged, or 1.6 or 2.0 liter diesel engines.
Model cars were assembled at the PSMA plant in the Kaluga region in 2010 - 2013. What kind of oil to pour into the Peugeot 308 engine depends on its modification and the year of manufacture of the car.
Repair of the input shaft of the automatic transmission Peugeot 307 AL4
Problems with the input shaft usually occur after a mileage of 150,000 km. The clutch housing and two friction packs (first/reverse gear and second/third/fourth gear) are installed on the shaft. The input shaft is first removed through the rear cover and disassembled for subsequent repairs. The stopper is removed and the return spring with the piston is removed. Then the E2 clutch housing retaining ring is loosened and
the first/reverse clutch pack Finally, the clutch pack piston retainer E1 and the piston itself are removed. When repairing the input shaft, a set of clutches and steel disks, pistons with retainers, Teflon o-rings and a bronze drum bushing E2/E1 Sonnax 144036-SX (37.9 × 35.2 mm x17) must be replaced.
How is the Peugeot 307 automatic transmission torque converter repaired at the Orbita service station?
Orbita is a specialized workshop for repairing Peugeot 307 automatic transmissions, equipped with modern Kinergo machines, allowing for a full cycle of gas turbine engine repairs. A high-precision lathe
cuts off the weld seam connecting the two halves of the torque converter into a single housing. The accuracy of a conventional screw-cutting lathe is not enough to perform such operations. Not every service station can afford a centering stand with a powerful vertical turning spindle.
After separating the housing, the master conducts a visual inspection and troubleshooting of all components of the torque converter
.
Then the parts are sent to an automatic washing machine filled with a special composition, where all surfaces, cavities and channels are cleaned under pressure. It's time to replace the locking pad. For this purpose, a thermal oven with smooth temperature control, a pressure pneumatic cylinder and a set of supplied disks is used. Typically, the friction layer is replaced during each valve body restoration procedure
. For gluing, a special composition, infrared radiation and high temperature are used.
After replacing oil seals, seals, bearings and other worn parts, the most crucial moment comes - welding the torque converter housing
. To do this, we use a high-precision welding stand, which eliminates even the slightest misalignment of the halves relative to each other. Thanks to the use of such high-class equipment, it is possible to exceed factory tolerances for radial runout and axial play.
The final stage is balancing the torque converter
and checking the tightness of the housing. For these purposes, a stand is used that pumps air into a gas turbine engine immersed in a container of water. A special pump hub weld testing adapter allows you to test the pump cover before the entire converter is fully welded.
What changes during a major overhaul of a Peugeot 307 gearbox at the Orbita service station?
When overhauling a Peugeot 307 automatic transmission, it is mandatory to change all gaskets and seals, friction and steel disc packs, rubber-coated pistons, Teflon rings, brake bands and drums, EPC and TCC pressure modulation solenoids, oil filter, bronze pump bushings - in a word, everything, which is subject to wear and tear. After disassembly and troubleshooting, the gearbox housing is washed in an ultrasonic bath
, all sensors and electrical wiring are checked. During assembly, the valve body is tested for leaks using a Vac-Test Sonnax vacuum tester.
If the machine has suffered from overheating
, rubber-coated pistons F1 (144902-EM 46 mm) and F2 (144912-EM 65 mm) must be replaced, regardless of their condition. If they are not replaced, the brake band will seize and burn out within the first week of operation. Any major repair is not complete without replacing the brake bands. If you do not replace it in time, you may end up having to replace the drum. The tape used is Borg Warner 144020-BW.
Every repair of a Peugeot 307 automatic requires replacement of Teflon rings
, since over time they lose their tightness and begin to leak oil. Low line pressure “fries” the clutches. The car literally immobilizes and you have to call a tow truck. When repairing the rear cover of an automatic transmission, the 4th gear piston and a set of seals are replaced. Between the hub and the brake drum there is a needle bearing, which also requires replacement. The pump seal fails most quickly, but it is rational to change all the seals along with it.
When repairing Peugeot 307 automatic transmissions, we use only high-quality components
Sonnax, Transtec, LYNX, Precision, ATOK and original spare parts, which are known for traditionally high quality.
Phased replacement
To carry out the procedure we will need tools and materials:
- original gear oil;
- a set of keys;
- seal for cork;
- funnel, hose for filling in new fluid;
- clean rags;
- container for draining waste.
Having pre-warmed the engine, and at the same time the transmission, change the oil in the box as follows:
- we drive the car into a pit or place it on a lift;
- unscrew the drain plug using a size 8 square wrench and drain the waste liquid into a pre-prepared container;
- when the old grease has drained as much as possible, tighten the plug, changing the seal if necessary;
- remove the cover from the breather located in the engine compartment;
- then, using a tube, slowly pour fresh lubricant into the hole;
- close the breather after the procedure.
Due to the absence of a control plug in the Peugeot Boxer gearbox, transmission fluid must be filled until the filler neck is completely filled. Timely measures taken to replace the gearbox lubricant will prevent rapid wear of the device and avoid the need for repairs.
