Sounds like a range switch, I think I remember reading a service bulletin on this, check with gm or an independent garage

Seems like the truck stays in 3rd gear and says range shift inhibited when u shut it off and start back up again

Attach a transmission diagnostic unit. Make sure the speed sensor is giving out the correct speed, as that is need for choosing the correct gear. Otherwise replace fluid and filter, this might also clear it up.
