Transmission(Hard Down Shift) - BMW Forum

Bunny Capricorn · 09-19-2005, 07:40 AM

I got my Tranny(92' e34 automatic-240k) rebuilt and since then I've been suffering from the "Hard Down Shift" from second to first gear. The frequency of this action is every so often.....but when it happens its ruff. I've noticed when I drive it in the gear selection "S3" it doesn't happen AT ALL.

So I beg the question.....What is this? I suspect that its a computer issue...I could be wrong....I need help guys!?!?

Where did you get the tranny rebuilt? BMW trannys are special and difficult to rebuild.

Considering that it's not even a BMW tranny...

I believe that model transmission IS adaptive, so you could try disconnecting the battery and letting it sit for 30 min to an hour to clear everything and start driving easy on it for the first little while until everything feels "right." If everything is cleared, cool - it was just a computer issue - if not then it could be time for a fluid change (which I doubt because you said since the rebuild...) or they could have done something wrong during the rebuild.

Good luck
