Hello everyone, I just got mine a month ago and heard the clunk sound too only after a week of driving. I saw this posting and thought that i might be able to add to it. The clunking sound only happens during take off after reversing out of my driveway. I called my sales rep and told me that it a common symptom. He had me talk to his service tech and told me the same thing. I had the same thing happening to my 2001 Silverado but I didn't think much of it until this posting. I've put 175,000 miles on my Silverado but now the transmission is starting to slip. I was told that I overload it. I use it for work. What do they expect!
