The selector shaft seal does have a minor leak but you nailed it with the pump seal. We put it on the rack the other day and left it overnight and determined the pump seal was definitely most of the fluid leak. Still trying to determine if my tv needs adjusted properly of if I have an internal problem before pull the transmission. If its internal I'm just gonna wait to do the 5.3/4L60E swap.
