Ok, a bit more information. I found a 2012 5.3 with the computer, wiring harness, electic gas pedal, and the 6L80e trans on ebay that has 1 yes 1 mile on the engine and trans. My understanding is that it was taken from a 2012 4X4 that was damaged in shipping.
I have been talking to Dave at Novak since my trip to Moab last April. I stopped by their shop and was very impressed with them. They have been very helpfull answering questions and giving me other people to talk to that have used their stuff. The website of their's is very good and has a wealth of information....some up dates are needed as they don't have the 6L80e trans info yet but other wise great source of info.
Looks like we have set a date of Jan 28th to get started. As soon as I post enough to be able to post pictures and run classified adds I will see if I can get some pictures.
I have a bunch of Jeep parts to sell if anyone is interested. The 4.0 motor and trans have less than 55,000 miles.
