I'm by no means experienced with this truck (only had it for about a month) but my '07 LE does the same thing. If you search the site you'll find other discussions on this topic. I think it's normal.
my 07 CC 4x4 does this every once in a while when i let off to start coasting to stop. im not punching it, it happens the most actually driving through the neborghood. i was going to get it checkeed out but if its not that big of a deal i will let it slide.2tall said:You aren't punching it then letting off quick are you? If so you could be hitting a shift point right when you let off and it thumps back. Scary but not a big problem... Just don't keep doing that. If that of course is the case...
