    Comments about National Oil Seal:

    It ended up being the wrong seal for what I was using but upon inspection it looks like a very nice seal for the money! Looks as good as OEM!

        I recommend purchasing a Haynes repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.

    • Q:

      These descriptions are god awful, do you mean the back of the transfer case or the back of the transmission? because the tranfer case output splines to the rear driveshaft.

        This is the output shaft seal for the transmission.

        This should go at the end (backside) of the transmission.

        I believe this seal goes at the very end of a Powerglide transmission and seals the trans to the yoke, just before the drive shaft. The surface of the yoke should be pristine no scratches if scored it will tear up the seal.
