Transfer case / Transmission issues

nukem0608 · 07-15-2012, 12:15 PM

Hey, I'm looking at buying a 335xi that has alot of HP at the wheels. Has there been any issues with AT cars dealing with the extensive HP increase, and if so what needs to be done in order to prevent damage i.e upgrades - Thanks

So I presume no one has come across any issues with AT - TTT

Ive been FBO no meth for quite a long time, only thing that failed was the Servo Motor / Set positioning motor. $500 fix if u diy.

08 35xi MT, mine was replaced at 40k miles. I bought it used with 25k, never a single hard launch, but no idea on previous owner. The TC started to have a louder than usual whine, thats it. After replacement, it was far quieter than when I bought it, making me suspect something was up prior to purchase.
