Transmission Experts Weigh In

I would say replace the selector shaft seal if you haven't done that already I think there is some really good info posted. Make sure you get a reasonably good quality filter so neck fits properly and doesn't break off, make sure you don't leave the old seal ring sticking up there, try to get the metal clad pan gasket, refill with Valvoline maxlife or dex VI with maybe 1/2 can of conditioner and don't worry about not getting all of the oil changed or putting the old oil back in. That's my 2 cents and what I did on both of mine at about 200,000K.
