C-4 reverse servo keeps breaking any ideas why?
I have a small block ford mustang with a C-4 3500 converter stock internals with a B&M shift kit.
I been running this set up for 7 years in this car with no trouble until the servo and the application fork for the reverse band broke
since then it has broke three times after i rebuild the trans changed the valve body with a different stock valve body readjusted the bands three times.the application fork is broken right down the middle like it has been broken by the servo pushing on it to hard.
I did not find anything that looked out of the ordinary inside the trans
has any one ever had this problem or does any body have any idea why this would happen
