I have a 66- 289A with Ford 4spd. The tranny keeps locking in a gear. I have to pull over and fight with it for a while before it comes out. It is getting worse and is now to the point where I can't drive the car. I have to trailer the car quite a way to get to a tranny shop. Any ideas on an easy fix ??? or is it a re and re of the transmission? I checked the linkage adjustment several times both before and after a lock-up and it is good. (the 1/4 inch rod through the holes) Thanks Much appreciated !!!
