Pontiac Repair: 2004 Sunfire Pontiac

Question
When I put into drive gear or park gear  or neutral gear no response..
Engine will run but no movement.....what may be wrong

Answer
Hi Janet.
As long as the transmission is full of fluid and the shift cable is not broken then there is an internal transmission failure like a pump or a torque converter and that is why it will not move. before it would not move on that key cycle was the transmission acting weird at all?
