Ok so I am happy to say that my gm transmission is fixed. I have been driving it for couple past weeks and no more limp mode.
Position of accumulator springs is apparently crucial for proper function of gearbox. If you get springs mixed up just like me, good rule of thumb that shortest spring goes into direct clutch accumulator this accumulator is also bigger diameter than other three in X5.
One from three remaining springs is much weaker and is made from thinner wire. This is also sometimes painted orenge and goes into 4-5 accumulator.
Last two springs might either be same or one of them can be longer by couple milimeters. If thats the case then the longer one goes into 1-2 shift accumulator.
Not putting the softest orange spring into 4-5 accumulator will cause 4-5 clutch slipping and damage. I have learned this the hard way but it that I have caught it in time as it seems to drive fine now 😀
Thx guys for help, car is working, repair cost me basically norhing and i have learned a lot about old automatic transmissiions.. Great success 😀
