Make sure they reset your adaptations in both your tranny and TC. Put them on the spot and ask if they know the re-learn procedure for the ZF8HP transmission. (its pretty easy, 25% throttle let transmission shift through all gears, then coast down through all gears, repeat min 6 times, then repeat in manual mode 6 times. You need a long stretch of road with little traffic to do right. It will relearn if you dont have that type of road but will take longer.

Thanks for the tips! Didn't know about that procedure for the transmission. Thought it was all done through the computer.

How much oil does the TC take? I bought one qt of this BMW TC oil. Hope that'll be enough. Taking the car to the shop on Wednesday. Will let you know how it goes.
