Extra information to read:
You have to know which auto trans you have. There was a GM and a ZF and the best way to tell is by the oil pan. 88k miles is low for transmission to have a catastrophic issue, even though I am not very good at auto trans troubleshooting.
BMW sourced automatic transmissions from GM of France and ZF of Germany. How to tell which is in your car is the question you have to check. Comparing with GM transmission’s fluid pan has smooth sides, the pan in the ZF transmission is ribbed. The GM transmission uses Dexron3 fluid while the ZF transmission uses a more exotic fluid.

Detailed operation procedure:
scan the engine computer (DME in BMWspeak)>>Scan the automatic transmission computer (EGS) for codes>> Find a reputable indie shop that specializes in bimmers at www.bimrs.org.
The requirement for the shop: have all of the BMW proprietary software to properly scan the computers.
