Well, I applied the infamous BMW fix...

I parked the car and turned it off. When I went back to it later, all was good. As if nothing happened. Transmission felt the same as it did previously.

I may be wrong here, but I get the sense that the BMW "compeuters" will sometimes get "confused" and a simple turn the car off and turn it on again seems to reset everything.

Now my problem is that swapping out the transmission fluid was the last thing on my list and I'm worried about doing it, now.

I plan on doing it in 3 weeks or so. So, if I don't see any other symptoms between now and then, I'm going to go for it.

Here's hoping I don't regret it!
