shift into fourth when pushed hard?? It shifts just fine when you accelerate smoothly, but when you push down the pedal all the way (to race or have some fun) the engine revs all the way up until the "check engine" light comes on and will not shift into the fourth gear. this is frustrating because i cant show my parents the problem and i have been to transmission shops and the dealer and no one can find any issues. is this problem normal?? am i pushing the car to hard??
