Rebuilt 727 no reverse took off pan help

Rear piston is out way to far. Usually the rear piston is not out of the bore that far b4 it gets cocked over. The adjustment was probably way to loose to start with. Hard to tell if the rear spring is even in the case. Did u put it into reverse when it was on high idle? It is definitely not a billet rear piston. By the colour of the spring it is mid 70s. Kim
