have your ECU checked for the version.......it sounds like you have the most recent version.

I'm sure you guys that had the final flash version noticed that the 1-2 upshift, and the 2-3 upshift happened at a much higher RPM/speed. That's the main reason that I didn't like this flash, aside from the fact that I didn't notice any improvement in the characteristics of the transmission. I was totally unhappy and frustrated with this car in this respect, but otherwise I loved it. The straw that broke the camels back was when I was driving back from a wedding I attended. The traffic was stop and go for many miles, and everytime I slowed down and then tried to accelerate, I would get the hard jerk/jolt, no matter how careful I was when pressing the accelerator pedal. My passengers even questioned why this was happening, including an 8 year old girl passenger who asked, "Is there something wrong with your car".
I was a limo driver years ago and I learned the proper essentials when transporting passengers, to avoid hard braking, smooth acceleration, and take turns at a reasonable speed, so the passengers had the most comfortable ride possible. I found it near impossible with my ES's setup!
I'm sure that steviej's '06 GS eliminated this problem, as it has done on my '07 ES.
