Hi, I've today disassembled a '57 Torqueflite. It seems that the unit was overhauled some years ago by a non-expert Torqueflite man ! There was some parts missing in the front clutch (cushion spring replaced by a steel plate..). As you expected damages to front & rear units (ft piston retainer / thrust washer / hub / rear return spring retainer, etc..). As there was too much play when they assembled the trans. they put two fiber washers on the input shaft !! But the question is about the "rear & front pump check valve", a spring like a hair clip which is in the regulator valve body. This valve has a bleed orifice on one side. The FSM says: " ..the bleed orifice is inward toward the front pump port cavity" which i translate in" bleed orifice toward the input shaft or toward the center of the trans". On the today's Torqueflite the bleed orifice is outward, to the exterior of the transmission. I think the FSM is right but someone could confirm ? And what happens with the bleed orifice outward ?
