ESOF Not Working, Used to have Manual Shift

DcMoore · Dec 15, 2011

So about a month ago, a guy(not sure if he's on PSA) drove up to me from Austin and we did a transmission swap, he took the ZF6 and I took his 4R100.

We both wanted to keep our transfer cases. HE had an ESOF and I had a manual shift. Well we couldn't get his t case split inorder to swap input shafts, so we decided it would be best to just swap t cases so he can get on the road.

SO I've got the correct wire harness going to the t case and the 4wd switch in the cab hooked up the the factory wire harness.. I've put in all fuses that were requried for this to work but it still doesn't. No 4wd light or anything.

Does my GEM have to be programmed for ESOF? Or am I missing something else?

found this on another forum, for an f150:
"For the original poster, the swap would be WAY more complex than it's worth. You'd need a properly-programmed GEM, the transfer case shift motor and encoder for the proper year, the correct wiring on the truck, the transfer case shift relays, and probably some other things I can't think of."
