1966 Dodge Dart 904 tranny.

Something is wrong inside. Get whomever rebuilt it to check it over. Could have the wrong rod on the vb. Kim
I agree. Something not right with the rod on the valve body. I will have the builder check it out. His first input was the neutral safety switch keeping the rod from moving past it and suggested l back the switch out a ways. I did to the point of the switch coming out. It made no difference!!!
