Default need help 91 jeep cherokee

I have a 1991 jeep Cherokee 4wd tub it had a 4.0 engine with a manual transmission. I'm putting back in it a 4.0 engine with automatic transmission how hard is that going to be.

Would be easier to sell it and buy a auto jeep,And some people want a stick so you could ask for more because of it.

^^x2^^ Although "tub" to me says it doesn't have the powertrain in it any longer, right? It'll be a "work in progress" for a long time because of the electronics. A 91 is probably a Renix.

1990 was last year for RENIX system. Regardless, you'll need to have the transmission control computer and wiring to make it work. Be easier if you were pulling everything from a complete donor vehicle, 1991 - 1995.
