Hey all! New guy here, so feel free to flame me if I didn't search well enough:

Hey everyone, I've posted up on another forum but wanted to see what you guys thought as well. I picked up a 2003 2500 with the LB7 for $500. It runs perfect, just got new injectors, new fuel lines, new fuel tank, new tie rods/ball joints/etc. It was a smoking deal I couldn't pass up - only 315,000 miles. Standard midwest rust on the rockers and the cab corners, but that's an easy fix.

Only thing.....it feels like the transfer case is stuck in neutral. At first, there was no power to the 4wd selector, so I checked the TREC fuse and it was blown. I replaced the fuse, and the neutral light comes on and stays on, and the truck says "service 4wd" and "Shift range inhibited". When shifting through the gears, it shifts from PRND321 just fine, but from Reverse to Park, there is a grinding noise (which makes me think that it's the transfer case).

Any ideas? I don't have a way to pull codes, otherwise I would do that. Tell me if I'm way off base here, but could it be the encoder or the TCCM?

Any input is greatly appreciated!
