Troubleshooting 2006 Wrangler 4.0 Manual

Ok, it probably needs a clutch, or the transfer case has a huge problem. I'd pull the transmission and inspect the clutch components, as that is the most likey culprit.

I've talked to a few people and I'm thinking maybe the pressure plate? Either way, I'll give her a good bath and start dropping the transmission. I really appreciate everyone's help. This is a great forum.
