I think that was the rub when I was looking into it. Since I was starting with an 05 auto the swap was more complicated. Seems I recall that if I had a wiring harness from a manual Jeep it would be a fairly easy swap. Certainly possible that I didn't find the correct info though.
I too had some issues with the 42RLE in my 05 Rubicon. Often times after running around in 4 low for a bit, it would shift weird when I went back to 2wd. For starters, try disconnecting the battery. This seemed to reset the shifting patterns. Workded for me every time I had shifting issues...
Re: V6 Tube Buggy w/Atlas for sale
Always wondered what happened to this chassis. First one I ever built with the help of Todd at Shotgun Fab. Glad to see it was put back together after the person I sold the buggy to parted it out. Good luck with the sale.

Will it run once you get it to fire on starting fluid? I had a similar issue with my Holley set up. Turned out the TPS went bad and the computer thought it was in "clear flood" when cranking.
