I've decided to replace the rear band servo piston, I did some research and the piston in the rear band is notorious for breaking, or eating the seals. I've got the valve body off but I'm kind of stumped on how to get the shaft out that the pivot arm for the rear band rotates on. Do I need to take the arm off and if I do, how do you get the shaft out?



I think it is possible to get the piston out without taking the apply lever out , loosen the rear band adjuster as much as possible and then pull the snap ring and holder out. If you have to remove the pin the shaft is on you have to pull the OD unit.

But since you have the valve body off you can air test the rear servo , the round hole that is between the accumulator piston and the rear servo is the apply port , use a rubber tipped air gun.
