96 ram Won't move

[Lunicy]

I have a 96 ram pickup (auto trans) That was in a small fire.

Having said that. We fixed it. Everything runs fine. The fire didn't burn any wires or relays. We changed the fluids and trans filter. Check the linkages.

The truck will move in neutral. (pushed of course) In gear it won't move.

When you put it in gear, it doesn't move at all. The idle doesn't slow down either.

Any solutions?
