Good information on the seal, looks like they took your advice. As for dropping the transmission, well with a Quicktme setup it would be a chore, lots of bots. So I will roll the dice and not plan on replacing the rear seal at this time. I do believe the 440 Source windage tray is partial culprit in this issue, not really the rear seal. That was a Mancini billet version, I have had good luck with them in the past.
