Hans, occasionally I get a "very slow" 1-2 shift when pulling away after startup--whether cold or warmed up. By very slow I mean I'm at part throttle and during that very first 1-2 shift the engine sometimes revs up yet the car actually slows acceleration to the point where my head dips forward a bit. After that initial occurrence, everything's fine. Did this ever happen to you? I'm also running Wait4Me's max performance tune. Just curious.

Thanks for the feedback. I get this occasional "slow shift" when pulling away for the first time, so it's a 1-2 shift in either mode. Good luck with the new tranny!
This has happened to me before. It use to happen a lot in my STS-V. It happened once in my V when I first got it. Since then I swapped the fluid to Amsoil and got Jesse's tune and it has not happened again. I don't know if either affected it or if it was a fluke.
