Oh boy, so you still sitting with problems even with a new box?Showtime100 said:Hey Freakazoid.
I'm sitting reading your posts and I can't believe how similar your saga is to mine. It's unreal. The good news is I DID get a new box eventually. Took about 2 months of back and forth to BMW. Have you met with anyone from ZF yet? Usually a ZF representative will come out and drive with you so you can demo the issues. The reason why your car felt worse after you got it back after the flush is that the Adaptation values for the box are reset to 0 the box then "learns" your driving style then adapts it's shift control logic accordingly. Mine was also super rough and jerky when shifting but it's DID get better. BUT my tale of woe continues I now have a ridiculously hard down shift as I come to a stop at a traffic light etc. I have had the soft wear reloaded and the adaptation values reset 4 times. Runs great for about 500km and the problem comes back. Short of taking the ENTIRE drivetrain out I don't see how it's gonna be solved. Patience is a virtue I guess. You are not alone brother! Hope it's gets sorted !
Show time.

And freak! My tale of woe has ended! My car must be female cos I had a little melt down after another series of shitty hard downshifts from the new box. And guess what? It hasn't done it once since I said to my fiancé that maybe I should sell it and get a manual! It's running like a dream shifts beautifully no jerking no shuddering I have fallen In love with it all over again!

The ZF rep I dealt with stated that the minimum kilometer count required for an adaptation cycle is 90km. So after the replacement of my box the shifting was also rough. The box soft wear does an adaption value snap shot every 300 to 400 shifts as it learns your driving style. It's then uses that info to shift at the most optimum time. Realistically my box took about 200km to really settle down. I also started driving in DS and MS A LOT more. And would vary driving from the standard mundane to more "spirited" etc. That seemed to do the trick the box is FINE now. No hiccups whatsoever. It's note the most comfy ride when driving in traffic in DS but I'm my opinion it helped the box by allowing it to adapt to as many variables as possible. Plus in DS you can REALLY show your merc driving family what the 335i is all about:bravo: good luck dude!

RedT said:Guys, I've been having similar symptoms on my e90 335i auto. On startup in the mornings, sounds like a horse startup and upshifting is jerky. I initially thought I was imaging things, but after reading this tread, I have to get it checkout. Im still under MP and I hope I dont get excuses from the dealership. Any advice for me.
