I pulled the tranny on my Dad's car to fix a leak from the bell housing area. The torque convertor seal is very straight forward to change out. I would like to change the o-ring on the front pump while I'm in here. I think this is actually where it was leaking from, as the torque convertor itself was bone dry. My question is does anyone know how to remove the front pump so that I can get at the o-ring. Tranny type is 722.320
