I forgot to add - the only other thought that I had was that CPU took somthing I did as "aggressive" and it "learned" that I wanted to drive aggressively.

After shutting down the vehicle, it unlearned this and went back to its normal programming.

That is the only thing that makes sense.

It really didn't feel like a "transmission" problem (in the sense of gears/clutches/moving parts and the like). It felt like a cpu problem. It seemed to be running a different profile than normal. There wasn't any slipping, hard shifts, clunking, etc, or anything that you would normally think of as mechanical problems.
