TCI 727 super street leaker NIGHTMARE!

I have tried the fluid level from middle of the safe area to 1 qt below full and it still leaks. as for a tranny cooler line restriction being the cause of my leak, I don't know how this could cause the tranny to leak out a qt of fluid when the car sits overnight. how tight are these front pump bushings supposed to fit anyway? my converter seems fairly snug but does rock around a bit in the bushing.
