Transmission Problems?

I own a 92 Galant with an automatic transmission. The thing came to a stop, and will not move in any gear. I see in the forum where people change control modules, and trannys to try to repair? Is there something I can check to determine which one is the problem?

I think I have the same problem as you. When you put it in reverse or any drive gear, are you able to push the car like it was in neutral? Have you been able to fix it or figure out what the problem is?
