Like others, I got the "cheap kit" at Advance Auto. It was $130 or so, plus discounted by whatever code I could find on the internet.
Beyond that, I did not use any special tools. I used an ordinary floor jack below the trans, as well as a strap wrapped around, OVER the roll bar, to a come-a-long hooked to a tree. The strap had 2 purposes. First, to keep the trans/xcase from tipping of the jack, and secondary was help in alignment.
This is not the best, nor safe way to do it. But it did work for me.
The biggest problems I had was removing the top 2 bolts on the bell-housing. I cheated and CUT OPEN the tunnel cover to allow access to those bolts. I also made sure I put a 2x4 in front of the engine. When the trans/case comes off, the whole engines tips forward... and it could ruin the radiator.
Also, sliding out the trans/case is a scary moment. It is the time when serious damage can occur if it does not come straight out. This is where the strap helped me. I slide it back, lowered, then PUSHED the Jeep forward a bit so I could work on the bell-housing/clutch, leaving the trans/case/splate ready to pop back in.
This is where you can make all sorts of bad shortcuts. I didn't resurface the flywheel, or remove the pilot bushing. and worst of all, when I could not get the trans to slide all the way back in... it tighted the bolts to force it in. All three shortcuts can, and have resulted in serious problems for others. I just didnt care. When things break, I fix them and move on. Sometimes I fix the things that broke fixing other things.
