Got my new truck running and it's a beast. Only problem is the transfer case is stuck in 2x4. No noise or problems as far as I can tell. Runs down the road just fine. I've put as much pressure as seems reasonable on the shifter -- nothing.

I have a shop manual and the transfer case troubleshooting section is virtually nonexistant.

I think it's a Borg-Warner 1345 (it's behind a 5.0 and C6)

Just not feeling like pulling it out... Any suggestions?
