335i xdrive f30 transmission jerking

nirvanabob · 11-26-2018, 06:36 PM

Hi there, does anyone has this problem with transmission and got it fixed?:
The transmission does harsh downshift, not really slipping, more like delays while changing the gears and more from the low gears like from the 3rd to 2nd and 2nd to 1th it has harsh/shaking downshift! I don't know how to explain!

Stock or tuned car? Try to disconnect the battery terminal over night. This should reset the gearbox programming. Might be placebo but I think it worked for me.

Mine does the same thing. May try that reset tomorrow. Slowing down is not smooth at all. Traffic is horrific. First German car and it drives me nuts!

How do you know? Did you had the same issue?

TK335iMSPT · 12-08-2018, 10:46 PM

Any update on this?

Hi everyone, I just got the car back a few days ago from the dealership and they said they had to reprogram the transmission ecu etc!
So, for the first day the car was (ok) and then the issue came back! Also now the first gear slipping from stand and still foot off the brake!
Monday I'm gonna call the dealership and bring it back asap! I'm start thinking that the issue with the gears is related to the transfer case!
