[QUOTE="idatahoe, post: 27887, member: 15122"] Thank you all for your replies! I can definitely reach out to [USER=8496]@NickTransmissions[/USER]. I think I need to get this in the stop to do some basic diagnosis first. I was doing some more reading on manual shift transfer cases. It sounds like the NP241C should work. I read about the 261 and someone said it has issues with the oil pump wearing through the case -- not sure if that's true or not. Still not sure if I want to swap the transfer case at all, but very disappointed if the transfer case indeed did randomly get into neutral and can't be put back. Worse than not having 4WD! It's hard to roll the vehicle as there's a bit of a hill and a fair bit of snow. I actually had to move the Tahoe out of the way this morning and had to use the tractor to give it a nudge down the hill. Will do some more clearing in the shop, then drag it back up the hill and into the shop. I think while I drag it, I can test park. I'll test putting the transfer case in neutral and then 2 high with the transmission in neutral, and the engine running. There's no lights on the dash though, so not sure if anything happens when I press those buttons. [/QUOTE]
