transfer case
Not too many H2 owners do these type of conversions and even less with the knowledge
You mentioned your set up is with a manual shift transfer case. We are in the process of converting my 2007 H2 to a 4l80e and have installed a Chev 2500 transfer case. This was done to facilitate the larger main shaft of the 4l80e and related strength. We realize the ALL wheel drive function is now traded for 2wheel drive.
I am tryng to retain the electronic shift for 4wheel HIGH and 4wheel LOW functions.
The factory wiring harness pluged into the 2500 tranfer case easily enough.
We started my new 408 turbo motor today and found it would NOT engage 4wheel high or 4wheel low. Even though the wiring harnesses pluged in, could there be something missing? Did NOT hear any sylonoid engagement!
Any help would be appreciated!

Mileage has settled at around 11. The guy who owns the truck is happy with it the way it is so we will not be changing the wiring any time soon. He built a nice console and the interior looks great. I will try to get some pics.
