hello here I am again after an attempt to repair the box but it failed I checked the pipe which for some had cracked above the body valve it was in very good condition viewtopic.php?p=960025#p960025 (but I did not check the others.. .) I did an oil change and I still have the same problem, backing up works but not driving its patina (but on the lifting bridge the wheels are turning) then the red dashboard light "PRND" fault code after 15/30 seconde
and impossible to choose the speed in sport or manual when it is not at fault it is on speed 1 but I cannot go up 2/3/4/5 "gear monitoring of multiplication"

Could be the ATF pump that’s failed. Seems like there’s not enough pressure to fully engage the clutches. Odd that it works in reverse though.

You are able to find one you could try a different valve body in case the problem is coming from that.

That’s where I’d start, I think. And I’d start saving for a new box.

You might find the information you are looking for in the parts catalogue:

I disassemble the valve body change the pressure valve with a transsgo with change of seals and invert the solenoids now it can drive in degraded mode (4th) and with the computer in 1st when it is not in degradation the box turns at 60 rpm but does not hang

Have you got the PRNS lit up on the dash?

at each start it is extinguished then in drive after an acceleration in 1st gear it goes into default prnds in red (safety 4th gear and I can drive)

Degraded mode is PRNDS red

That’s why you’ve only got 4th gear. In limp mode you only get 4th and reverse. What codes do you have now?

the same as before I just have the 4th which rolls more x)

finally I bought a second-hand box on ovoko at 970 euros with delivery (I had also found the famous water radiator which costs 2500 euros at 70 euros on this site and it was nikel) I have just reassembled the box I don't know how to do what doesn't fall off the box ^^ everything is back up all I need is the fluids and I'm testing it in the weeks

Is your car fixed now?
