Hello, and thanks for using JustAnswer, my name is ***** ***** I have been an Automotive Technician for over 15 years.

I was able to locate a TSB from GM about a known problem with the detent that holds the shift linkage in the 4LO is known to wear out or loose tension. I have attached the TSB to this message. Hopefully adjusting the shift linkage will help.

I am sorry I am not able to find very much information about the 4WD system on your truck. I will opt out and hopefully a tech with access to GM information might be able to help solve your 4WD issue
