727 Rebuild Woes: Oil Pump stator / drum air leak

"added a 25" end play shim between the two clutches"....If you mean between the drums, never insert more than one washer between the drums; an extra one won't stay in place. (over 2 feet is a LOT!) And never air check unloaded drums. (damages the seals). I see a lot of terms that I'm not familiar with..I guess we're supposed to know what you're talking about. Clutch basket, assembly goo, straight up rebuild ; I think maybe if the repair you're doing is as imprecise as your use of terminology, this thing isn't going to work very well for very long. Helpful hint: made up terminology will discourage others from chiming in.
