I’m currently in the process of swapping a 392 Hemi with the 8hp75 and my original rubicon transfercase into my 2 door.
The engine and transmission came from a wrecked Jeep and iv sourced a lot of the parts from Mopar to make it as much as plug and play as possible.
I have the engine running but currently am having transmission issues. The Jeep will start and run but when you attempt to change gears it flashes and says shift to park. Everything I’m reading from the codes says it’s low on fluid. Iv pulled the fill plug to add fluid but it is already full and I can’t get it in gear to fully fill it.
After hooking HP tuners it looks like the transmission is loosing communication with the ecm.
I am looking to find a Pinout on the ecm and harness to start checking for a bad ground or power wire. I have what looks to be everything I need hooked up from the engine harness and new firewall harness but I could be missing something.
