Hey I have a 2015 Silverado 4x4 and I hear a clunk when I shift to reverse. Doesn’t happen all the time, but usually will happen. Took it to the shop today and they told me they heard the clunk coming from the transfer case. Have no idea what it could be. Any help please. 

Welcome to the site.

 

First, how about some info on the truck, miles, are you the original owner, mods done to the truck, maintenance done, and anything else you can share helps get better answers/guesses.

It’s a 1500 6.2l ltz. I am not the 1st owner I am the 3rd. 75,000 miles on it. I just got it about a month ago.

Did they check the fluid in the T Case to see what it looked like? Any metal shavings (excessive) present? Does the 4WD system work/engage?
