First off, thanks for the quick response. One more question: In your DIY, should I just get as far as replacing the Input Shaft bearing (about 2/3 of the way through the first post) and put it back together? It's a bit overwhelming and, to be honest, scary looking for someone who has never seen the inside of a transmission. If I could get away with only buying a bearing and few gaskets/seals instead of a whole rebuild kit, I would like to. Unless it's not a good idea. I've never done anything of this magnitude before.

Thanks! I never would have thought of doing that.
