Well, for starters, the motor must be OK. It is moving the transfer case selector, but just not how you want it to move.
Are your front hubs locked or unlocked? If the hubs are unlocked when you try to put the transfer case in 4H or 4L you can cause the case to grind and it will act like it doesn't want to go in. This was pointed out to me, I tried some tests and verified it was true.
You may have a hub problem instead of a transfer case problem.

OK, lots of diagnosis work involved on this one, so are you willing? 
I understand that it tries to go to 4x4 by default.
You have to do the following things. Unplug the fuse(s) and relay(s) associated with ESOF.
Plug the fuses in first. Shouldn't change anything.
Then, plug in the relays one by one. I think there are two.
Report back as to what happens, and we'll continue ...
This is all with the motor plugged in.
thanks!

My 2007 PSD 4X4 won't unlock the xfer case in 2WD. Took it to the dealer, he locked/unlocked hubs and went from neutral to drive and my gosh the grinding noise drew a crowd in the service bay. Still won't disengage. Taking it for service on the 5th and will report back what the fix was

When it hit what I think was 4 low the other day, the truck motor cut off and the speedo went up to 100.
I will try what you suggested and see what happens.

You have a short in the wiring or the gem module is going, seen this before
To trouble shoot you will need the wiring schematic for the yr of the truck
This isn't a easy find.
Does it happen after a rain storm ? ck the relay box under the hood for water or the fuse box under the dash.
or a rough road?

Yes that is the relay box. What is up with the duct tape? Not a good sign, possibly water in there.
The Gem is located behind the fuse box.
