Hello,

I have a problem with the automatic transmission in my V70 T5 2000 year. The automatic transmission has been damaged (AW55-50SN 9480897) and I have to buy a different one, however, the T5 engine is almost inaccessible. Can I buy a box from another engine for my T5? Thank you in advance for your help.

Best regards,
Marek

Hopefully precopster will chime in as he is one of the masters of the AW55-50SN.

Sounds like you are asking what transmissions interchange with your 2000 V70 T5.

What exactly is wrong with the transmission? Is the valve body fully operational? Can the failed components be rebuilt? What is the supply of used transmissions like in Poland?

I received an error about the low pressure of the SLS valve. So I dismantled the valves, undressed them and thoroughly washed them. Then I folded and reinstalled. After this operation, the car did not have the strength to move from the garage. I left the garage somehow and the car did not want to change gear for two - when I tried to change it was a sharp jerk and the car seemed to slow down. A moment later it was like the smell of a burned clutch. From that moment when I'm putting on D this car is standing where I'm putting on P, R, N is a car. he tries to move but he has absolutely no strength. The diagnostic interface (vida) does not show any errors regarding the chest.

Many good pieces of information. Based on what you are saying your transmission has actually gotten worse since you tried the repair.

First thing to look at is how much transmission fluid is in the vehicle. Is it filled while running in park and warmed up. Second, did you inadvertently drain the fluid from the wrong plug and cause one of the bands to disengage? Drain plug is on the pan and accessed from below. Did you perform work on or disturb the transmission selector part on the transmission?

Check you oil level if it is correct how dirty is it now? Hopefully you did not cause too much clutch damage. Next I would go back in the valve body and make sure you installed the solenoids correctly. If I recall there are directional orifices that must be positioned correctly (it may be a mounting bracket). Either way make sure the solenoids are fully inserted and the mounting bracket is properly positioned. Then see how it operates.

If the car is still having issues you could have a clogged filter or internal damage other than the clutch disks.

In the latter part of the post I listed above is a discussion of back flushing the internal filter - you may want to explore this when the valve body is off the car. I would try this - be a pioneer - as basically everything is already taken apart.
