seems like every 22r/re has a diesaling sound to it at one point or another, my 91 had and my 94 had it, i through in a bottle of lucas oil with every oil change and took care of both of them. yours might be a different case but i would start with that.
as for the tranny i have no idea how to rebuild one, never had to. but it sounds like it could use a fluid change and through in some lucas or slick 50 or something like that.
