Slipping Lock-up , DTC 323.....
 

HI,

on my '93 850 T5-5 wagon, my gearbox decided to quit....

i made an almost stage 0 on the gearbox :

-replaced 4 solenoids for new ones
- Replaced the PNP switch with a new one
- Replaced the 2 piston pins from SONNAX
- replaced the engine speed sensor
- many transmission flushes...
- Checked and cleaned every connector, checked for connections
- Replaced the ECU for a know " good one"
- Reseted DTC... many times....
- launched the TEST sequence for electric components : everything seems OK

And the gearbox is still slipping..... no lock-up... and of course over heating !!! and the car is slushy... not in limp mode, but veeeeeeery soft......

as somebody ever managed to fix this issue ??? i mean.... everybody over the net is suffering this problem... but i can't see any real answer...

thanks a lot !
