My car goes back in on Wednesday, third time to try to fix this. My NEW SA thinks that the computer got messed up from the broken sleeve and leaking fluid and first wants to try to reset the transmission software and computer and then go from there. If it was that easy, I would hope that my prior SA would have been willing to do that, but he was an ass and wasn't willing to be proactive. Don't want to rehash another thread, but the guy wouldn't do anything because the car wasn't giving an error code and said I was making the problem up. As with someone else on this thread, he told me that the 6 series had transmission problems, but not the 5 series and 545i specifically. I think this thread would say otherwise.
Anyway, at least this new SA has a plan of attack, and he went for a test drive with me and felt the hesitations about 37 mph. We'll see what happens. I'll send you a PM if their refresh fix doesn't work.
