GMTCCK2500
Newbie
I'm new to the forum. Last summer I bought my '00 k2500 and twice now when I hit some mud and press 4 hi I have a popping sound. It isn't constant, it just does it then acts normal. Doesn't do it when I try to make it do it in my yard. The front wheels pull even after the sound. I am stumped. It has push button tcase non auto trac. By the way, what tcase is this?
