There are no longer mechanics that work on BMW's.
Today we have parts replacers. BMW does not allow internal repairs, so your car would get a "fresh one". I do not think a dealer should try changing the trans fluid. AND if they did... they surely would not use a non approved trans oil like BG Product's SyncroShift oil.
