Fullback

Yes mine will do that occasionally as well, I agree, I don’t think it’s that big of a deal. I can set my cruise at any speed on miles of flat highway and it will randomly clunk about every 60 seconds. While doing so the RPMs will fluctuate plus and minus 200 or so. I just fear the dealership is going to tell me that they couldn’t find anything or that it’s normal.

I have a 2018 Silverado LT with a six speed tranny. Cruising at any speed, I will experience a random clunk for no apparent reason! Almost like it can’t make up its mind whether to shift up or down. Just a random clunk with a slight slipping feeling.. anyone out there with the same thing? Only 10,000 miles on this vehicle! Did I buy a lemon?
