Chevrolet Cavalier 2003 80000 miles
My problem started after the car overheated, the cylinder head cracked because of the heat and it needed to be replaced. At the same time, the transmission oil was changed. The T/C light started turning on and, when it does so, every time I change the gears, they seem to generate a kick in the engine. It is not the only case but, every time I turn on the air conditioning, this failure takes place. If I am driving and the T/C light is off, then there is no gear failure either. The starter light sometimes turns on by itself as well. Something else: when the car stops moving, the air conditioning stops cooling too. Two sensors have been changed and a tuning was made, but the problems are still with me. Any recommendations?
