I have been driving a 2003 Chevrolet cavalier and the automatic shift is stuck and can only shift to neutral and drive since Thursday morning. It wont go up to reverse and parking and down to the other 3 shifts.
This first happened last April but somehow with the right grip or pressure was able to get back to all the other shifts. Since then it happened 2-3 times as I can remember and now could be getting worse.
Any step by step help like checking the wires and cable etc… would be very much appreciated.
