Will the transmition from a 1990 4.0L 4wd swap with a 1995 2wd 4.0L ? If, not can I swap torque converters?

NO - for several reasons - the 1990 has a small pilot hole and
bearing in the main shaft stub that is too small for a larger transmission for a post 92 inline six. The tail shaft might be
different resulting in the wrong clocking of the transfer case.

Your problem if you have a 89-91 six is the pilot hole is too
small for the larger bearing and race so you have to machine the
hole for the larger shaft on later transissions... Which means the
main has to come out and go to the machine shop.

If you had a larger - later six - you could put a 89-91 tranny in
if you fitted a spacer in the pilot hole.
