anyone with transmission knowledge would be helpfull

I have a 2000 ga with 135k on it. When i am giving it more than half throttle the trandmission will hessitate to shift. when i shift it manually it will shift firmly and quickly. the fluid is fresh. It also shifts very nicely when it is cold. Is there anything i can do to firm up the shifts so the trans will last as long as possible????

I have a similar problem and shifting manually or putting the shifter in 2nd seems to help with the 1-2 shift. It only shifts lazily at 75% or greater throttle, otherwise it seems fine. I'm guessing it has something to do with the transmission line pressure because I've heard that putting the shifter in 2nd raises the pressure and can make the tranny shift faster. I've also heard it was a somewhat common problem, and there really isn't too much you can do about it unless you get a tuner to change the line pressure.
