hello i have a 2005 grnadprix, and i had asked this same question aout a week ago about my cars rpms going up and down and the car jerkining back and forth. this is going on while the car is moving, i got a response as far as checking the gasket to the engine bay, but i had the car looked at again and they told me it was the transmission, can anyone let me know if this sounds like a transmission issue? and my next question is my lock on the driver side door wont open and it takes like ten minutes for the key to turn to the left or the right does anyone know how much it is to to that fixed?
