I have a 65 mustang with a c4 trans and was given a Transgo reprogramming kit with part # 47-3 and was wondering if it would fit in my 65 trans. I have installed a B&M pro shifter and i cannot hold 2nd gear. Adjusted it many times too no success.
talk to peformance automatic. they make the best parts for the c4. i have a 65 c4 with a reverse manual valve and its awesome. it also has a tci 1/2 servo.
