Here's my update:
I still have some shudder when letting my foot off the brake. It seems to happen after the car has been driving for a while or if I come to a quick stop (like sudden traffic on the PA Turnpike). I'll see what happens after a 1000 miles (which will be a couple of weeks for me). Has to do the adaptive learning again.
The shifting seems to be better, though, especially when going from 1st to 2nd and 2nd to 3rd. When making a turn (slowing down for the turn, then pressing on the gas) it seems to be a lot smoother. So far I haven't had the "pause and lurch". It also looks like it's holding the higher gears a little longer to get better acceleration.
Haven't had a chance to test the rollback fix.
