    I have a 2008 2500HD w/ 6.0 and 6 speed auto. It sometimes feels like it downshifts when I'm sitting at a stop light. The first time it happened, I thought somebody ran in to the rear of my truck. Has anyone else noticed this, and is it anything to be concerned about?
    It has 3,070 miles on it.
