I just purchased a very well maintained 92 735i with about 150k miles on it and it seems to have a problem with the auto trans when diving at a steady pace of about 40 to 45 mph. Right in this speed range the trans begins "searching" between two gears. If I accelerate past this, the trans kicks down and the engine revs to the next shift point, then it goes away, but if I don't accelerate (or decelerate..) out of this range, the car feels as though it is "bucking" of hesitating as a result of the "searching". Has any one heard of this and is there a way to eliminate this through adjusting the shift points on the trans or some other way to minimize this?? As far as I can tell based on the service records, the transmission was replaced (by the factory) at about 100k miles by the previous owner. Any insight would be appreciated.
