I saw a thread says BMW transmission control unit learns driver style. Is it true?
the slam was happening to me always after I did drive it very harsh and after then always happened below 50mph. or just the transmission sucks? my SA told me not to change Tranny fluid he said it could intensify the problem, though an indy (pretty well known in my area) strongly suggested to change the fluid. but the SA was more knowlegable. so I will keep it for a while. Anway the software update does not seem to be very helpful to me. it was done at 10000miles. 60mph driving saves the day. X5 driving 60mph on 75mph limit freeway -_-
