tj engine and trans in a yj?

Can you swap an engine and trans from a tj into a yj? I have a 93 with a 4.0 3 spd auto. I was given a 4.0 4 spd auto set up... Is it swappable?

3 spd is on the column.
4 spd is on the floor..

The engines are the same size.. So id assume the mounting for them is the same..

Would the 4 spd trans mount up to the existing transfercase? Or would i need a new transfercase?

I it might take some cosmetic work like removing the original shifter...

Chevy still runs deep but I wanted to understand again! O|||O

Look up AW4 swaps on the forum. It has been done numerous times from XJ and TJ. You need the harness and controller. A meter the schematics and a good sense of electrical wiring. Yes, you can do it. I would do some looking though. It seems like it mught be easier to keep the YJ electronics and adapt the AW4.
