I had the dealer take out my transmission and replace all the seals about 1 year ago, and they said the rest of the tranny was fine and had quite a ways to go, and they reinstalled it, all the leaks were gone, but it still does a clunk downshift from 4th gear when coming to a stop. Our 83 is far smoother, it engages drive and reverse with no feeling at all, and does not make the clunk. I don't really mind it, but even with the dealer servicing it and putting it back in/adjusting it, the clunk didn't go away.
