NO CODES COME UP? the tranny is new and i,ve had it checked out,it has some corvete upgrade (auto sport ) package ,so it shifts a little quicker,but nothing non stock. HELP !!

Does that happen when the car is cold? ...and did you have it tuned (professionally or a buddy)? my car use to do that when it was cold. All i did was took it back to the guy that tuned it and had him change the rpm's of my vehicle a little higher. you know how when you get in a vehicle and the rpms start at about 1300rpms for a couple of seconds till it warms up, then it drops back down to normal idle. well i told my buddy to tune that part and the problem went away.

i think thats what your talking about?????
