Details: 55 51sn DIY repair from a real master for the site my.housecope.com.
Repair of automatic transmissions AW55-50SN and AW55-51SN, installed on cars of the brands Volvo (Volvo), Saab (SAAB), Opel (Opel), less often on Chevrolet (Chevrolet), Daewoo (Daewoo), Lancia (Lancia), Renault (Renault) and etc.
Automatic transmission 55-50 SN has arrived for repair due to a typical problem - overheating. The driver talked about slippage, improper gear changes and double loading when the car was at a standstill.
The viscera are common for such a situation:
torn out bushing (in the photo below you can compare the state “before” and “after” the breakdown)
and all accompanying, failed automatic transmission elements.
(in the photo below you can compare the state “before” and “after” the breakdown)
Repair of automatic transmission 55-50 SN consisted of replacing bushings, filters, clutches, underdrive drum, brake band and standard updates from the repair kit. The valve body was also repaired. Some car services buy new or rebuilt valve bodies for these boxes. We do not need to do this, as our craftsmen repair them on their own. This is one of the indicators of professionalism, which not only enhances the workshop's image, but also reduces the cost of repairs.
The repair was completed successfully, complete restoration of normal functioning.

The story is that a NEW valve body is coming to me on aisin. While driving, I want to sell the old one, now it's in the car. At work 1-2-3-4-5, 5-4-3-2-1 are almost ideal, but sometimes the transition 2-3 is slightly felt, it is felt. There are no kicks, jerks, and even more blows or slippage. The main disadvantage (for this reason, and change to a new one) is the reverse. Everything is perfect on a cold one, on a hot one there is a jolt, and sometimes not. Aira car of 2009. Mileage 150K. While the new block is moving, there is an opportunity to test it by car. In principle, I don’t want to restore it and so on in Minsk. If no one takes it away before the arrival of the new unit, I will send it to Moscow to trusted people for restoration and will lie like a spare wheel.

Why not just indicate the price of the question? After all, fortune-telling on coffee grounds does not speed up the solution of the problem))) Sorry, maybe I somehow misread your message and you return it without money? Well, in that case, ready to pick up!

In 09, the automatic transmission was 55-51 if I'm not mistaken

Your car needs a valve body from 55-51, software for 55-50 is slightly different! Will not work properly.

The code for the saab box, which costs 55560552. Transmission code FA57C05 or FA57C04 Judging by the code, they began to put them in bespectacled people from 07 onwards. Exactly boxes with a different code. Perhaps this is 51 aisin. As for the valve body, maybe it is the same as in 2002-2006

On 55-50 and 55-51 there are different valve bodies, and your gearbox is most likely 55-51 and the valve body from 55-50 will not work correctly

Automatic transmission Aisin Warner AW55-50SN, AW55-51SN (AF33, RE5F22A)
The 5-speed automatic transmission AW55-50SN was designed by the Aisin engineers at the end of the last century as an exclusive version of the 5-speed automatic transmission for non-Toyota front-wheel drive vehicles with engines from 2 to 3 liters. A complete list of all cars using this automatic transmission does not fit on one sheet (below) and every year all new models receive this popular automatic transmission. Kazakh Chevrolet Epica, All Volvos, Saabs and many others preferred this automatic transmission to all other 5-speed units.
Some of the design solutions were taken from the successful predecessor - the 4-speed AW50-40. The box turned out to be so successful that even competitors - Nissan, General Motors chose the AW55 for their popular cars, simultaneously releasing their RE5R05A (JR507E) (Nissan-Jatko) and 5L40E / 5L50E (GM - Europe).
The AW55-50SN incorporates many new technologies to improve vehicle performance, comfort and environmental performance.
The fate of the automatic transmission was handed over to the young "computer geniuses" of automakers, such as those that program the autopilots of airplanes.
An innovation is the use of linear solenoids (SL * - Solenoid Linear -) for smooth “parallel” gear shifting. It is this solenoid that makes the changeover invisible and with virtually no loss of power flow. But due to the fact that, again, the same clutches slipping, accelerate (or slow down) the shafts.
Another innovation - the “slip mode” of blocking the gas turbine engine forced the use of new graphite materials. The blocking of the gas turbine engine began to be switched on by the linear solenoid SLU already starting from the second speed (with the pedal “to the floor”), without waiting for a slow acceleration with the help of the turbine wheels. That led to unexpectedly rapid wear of the friction lining of the torque converter and, as a result, to the failure of the “brains” of the automatic transmission - the valve body.
This more abrasion-resistant and well “sticking” carbon clutch, having got into the oil with dust, began to gnaw out and clog all the thin parts of the valve body and solenoids with stone deposits. How cholesterol from pork shish kebab clogs the brain vessels of “stroke patients”. The processes of "ischemic disease of the automatic transmission of the brain" are described in more detail here.
In 2003, the AW55-51SN modification was developed with an improved valve body for all-wheel drive cars, which was used for Volvo (S40-S70) and Infiniti I35.
The AW55-50SN developed for Nissan vehicles is known as the RE5F22A. It is closely related to the Jatco AW235 transmission in detail. According to the GM (Saab, Opel) classification, the AW55 is called AF33.
fin filter without fin AW55-50
AW55-50 is designed for torque up to 330Nm and is the most popular Aisin box for repair in our market (among non-Toyota cars).
Filters for it have several modifications:
- Automatic transmission filter "with rib" 351010 and
The filter with a rib (wrib) fits almost all automatic transmissions. No rib filter (w.orib) - for a narrower range of machines.
In 2005, a new modification of the filter without rib (w.orib) 351010C was released for Chevrolet pallets.
Filter without fin, AW55-50SN / 51SN WO / RIB Chevrolet 2005-Up
spare parts for the repair of this automatic transmission (online store) Repair kits 351002 are produced by many manufacturers. This automatic transmission is not sensitive to the difference in the quality of repair kits, therefore, everyone chooses from Prescription to Transtec.
repair kit AW55-50 The frequent sale of complete clutch kits 351003 suggests that the clutch and brake packages are fairly balanced.
In the first years (until 2005), the clutches of the C2-Direct package failed more often than others, and the drum design was slightly modified, and the thickness of the clutches (351106) was reduced, after which they began to serve longer.
“Childhood disease” in the first year of production was the ingress of antifreeze into ATF oil. The very mechanics of the box are designed and executed perfectly, like everything Aisin does. But when the box is produced universal for different manufacturers, it will be programmed by “foreign” programmers for their engines and their own type of driver, for different torque converters, cooling radiators, then, like seven nannies - expect trouble.
There were other childhood illnesses as well. In particular with hydraulic valve plates. All automatic transmission manufacturers are struggling with this problem, and since 2004, AW55 valve bodies have begun to serve much longer, requiring only repairs and routine cleaning.

The car is staked now.
Duck there is some kind of situation then.
In general, I had a problem that the clutch collapsed and the filter clogged. The pressure is gone. The solenoid valve body has always worked perfectly, before the repair.
As the automatic transmission was repaired, the car first started to go with the 3rd gear. Changed the line pressure solenoid and cheers. went.
It was impossible to press the gas sharply for the first thousand km. OK. If you do not press the gas sharply, then the switching is quite smooth, as it should be.
After a thousand kilometers, I stepped on the gas and was very upset, because there was a kick from second to third gear.
Further. On a cold one, when you turn on the drive, there is a large delay in the region of 2 or 3 seconds, then the car seems to go to the second one. then the 3rd and so on. As it warms up, I get under way with the first. .as it should be.
And the most important thing is that after 100 km per hour the car goes into emergency mode. Torque converter lock-up slip occurs. The officials told me that. After driving for a short time, it smells of transmission oil from the engine compartment.
In general, that's why now the car just stands. I don’t want to spend money on repairs that suggest something and possibly repair it.
Announced another 26tr for repair. .. yes yuhan it fell to me. I sell a wheelbarrow anyway, one way or another. It's just that everything has its time. ..
