WJ Manual Transmission Swap

Has anyone performed a manual trans swap on a 4.0 WJ w/ a 42re trans and a 242 case? Even just a parts list would be good!

Agitated Pancakes did the swap with a 4.7 WJ, I have a 4.0. I'm sure I can follow some of his setup like pedals and the like. I've been doing some digging and I think Im going to go with a NV3550 and use flywheel out the same year XJ. If they have the same distributorless Ignition then I shouldn't have any issues with the Crank Sensor/Timing etc.

A manual Trans out of a Cherokee or any jeep with the 4.0. The Asin trannys from a Cherokee are good. If I had a WJ with the 4.0 I'd much rather have a AW4 than a 42re.

I thought about taking an engine and trans from a late TJ. It never went farther than just a thought, but it would be a fun project. I'm interested if you can actually get it done. Good luck!

'01 - '06 TJ blocks are the same as WJ blocks. The early TJ's and all XJ's use a different block.

I did a pretty good amount of research on this and there don't seem to be too many documented cases of it happening on a 4.0 wj. I found 3 people who have done it just on the jeep forum and the most documented was this one http://www.jeepforum.com/forum/f310/...-swap-1418297/
I plan on also using an AX-15 if I can get one for a good price including pedals. I don't plan on this for a while though. If you end up doing it good luck and make a write up please
