I've done it.

First you will spend one long-ass day doing this. I understand now why they charge $1200-$1400 to do a clutch in this vehicle. If you get alower estimate you will be charged this much in the end. It took me 11 hours take 2 hours for lunch and a much needed beer break and to have the flywheel resurfaced. Second get some different colored spray paint to color code all the wire connections going into this tranny/transfercase. There are lots of them and they all look the same. Get yourself a tranny jack because this combo is heavy! There are lots of exhaust pieces, cross members and skid plates to remove and install. Take a pic of everything before you start, I had an extra skid plat that I couldn't figure out how it went bak on. I had to crawl under another trooper to find out. Don't forget a rear engine oil seal, I replaced mine when I saw it was leaking and cut down a quart of oil usage later on. Other than that it's a typical tranny removal. A real beyotch!
