I was experiencing the transmission jump when shifting down from 2nd to 1st gear, i went to the stealers they advised a software upgrade, if it didnt solve the problem, then i need to replace the transmission.
The $200.00 software upgrade worked for 2 days.
I went to my mechanic, (he services my other cars) with a printed instruction of this post. got the gasket and filter from my local stealer, the oil from the Audi dealer. it has been 5 days now, and so far i drove 200 miles, both hwy n local, (as i am writing this i am knocking on a big piece of wood next to me)no problems,, it took six quarts. the car feels smooth.

Thank you x5 world
