60 Rolls on incline in Park only after engine shut off

Post by jscherer26 »

If my '60 cruiseomatic is in Park on a slight incline, engine running, its stays in place. As soon as I shut the engine off, it rolls back to the tire chocks. Did this about 5 times to be sure. If its parked on a level surface, engine running, I can't budge it, but when its off, I can roll it forward or backwards.

My mechanic discovered this specific behavior and it doesn't understand why it is occurring. All indications are that is in Park. It drives well, transmission shifts as it should.
