It sounds like you're replacing a 465 with a 465. If yes, just unbolt the old and bolt in the new. They should be perfectly identical.
 This probably shouldn't need to be said, but please use a floor jack or a tranny jack. I learned the hard way that it is heavy and hard to lift off of your chest and into place.

The only time there might be a problem is early vs late model splines on 4x4 boxes...  2wd should bolt right in.

Thanks guys. I'll try to do the swap during summer, I should have enough money then.

Not a question of difficulty. Decent used transmissions are just cheaper than rebuilding one.
