Th350 seal removal

Hello I recently had a substantial leak in my th350 i narrowed it down the pump seals, i dropped the tranny and pulled the pump then removed the o-ring and the gasket successfully, but im unsure of the technique to remove the seal on the input shaft, in the process of trying the removal i seemed to damage a spring (shown on attachment) if anyone could help me on the proper way of removal it would be much appreciated.

Thanks, SBC-S-15

This spring is just the spring fron the lip of the seal you ar attempting to remove.
If you have the pump off of the transmission take the five 1/2 inch bolts off and the pump will come apart.
Then use a brass punch fron the back side and drive the seal out.
While you are at it you might want to replace the bushing that supports the torque converter. When the seal leaks the bushing seems to go bad too. It is like the chicken and the egg. I never know which came first I just know both need to be replaced or you will be back doing this very same fix again.

Have Fun
