4wd GMC Sierra tow vehicle

Different year, different model, same mfg, same problem....both a position sensor switch and related solenoid went bad overnight: lever moved fine, nothing happened in the innards.

Straightforward fix (doesn't mean inexpensive) at the local tranny shop; most challenging part was getting the vehicle out of the condo parking lot. Ended up with a "come back at 10:00 p.m." charge from the wrecker as well as a couple of PO'd neighbors since it was unavoidable to block one road for about 15 minutes.

It's broke, and needs repairing at the dealer, or reliable trans shop

Probably a toad and the electronically actuated transfer case won’t shift out of neutral.
No , don’t know what’s wrong. Bad switch or bad solenoid are the 2 most obvious issues though.

Will the shift lever move and nothing happens or is the shift lever stuck?

That's an impossible question. What year are we talking about? Are you asking about neutral in the transfer case or the transmission? Manual transfer case or electric transfer case? Manual transmission or automatic transmission?

While lacking your truck’s year, there is no need for posting help or support.

Year?
