Has anyone else ever done this, and if so did it cause any kind of damage to the automatic transmission even with the transfer case in Neutral. If damaged what were the symptoms and what did it cost to repair?
While still hooked behind the coach I put the transfer case back in 2WD, started the engine, and ran the tranny through the gears. It attempted to move, both forward and backward and I didn't notice any adverse noise. Won't know for sure about driveability until we reach our destination tomorrow and unhook the Wrangler. I probably won't sleep very well tonight thinking about this.
According to some of the transmission techs for Jeep I've spoken with, the primary reason for putting them in Park and or, leaving a stick in gear is to prevent "sympathetic" gear and bearing turning that otherwise, would not and or, does not receive any lube from "wrong direction power". That is, things being turned due to power being supplied from the output shaft, rather than the input shaft which, powers things up that provide lube.
The chances you've done ANY damage, are phenomenally low. When you get to your destination, do all your normal un-hooking and drive the thing all over the place and watch, listen, and feel for anything "odd" that you would normally not have. Good luck.
