My 1966 Willys CJ5 was operating fine and then.... out of nowhere, it won't move forward in 1st, 2nd, or 3rd and won't move backwards in reverse. The engine runs fine, she starts right up. But no movement. I can start the engine without the clutch pressed in - it's as if I'm starting the engine in neutral. Anyone experience this before? I'm just getting my feet wet as a Willys owner so any advice on what the problem might be is much appreciated.
