I have a 21 with 39k on the clock. Hard shifting up and down, and the occasional huge surge when nearly stopped. Took it to the dealer, gave a description. They Ran some tests and rebuilt it. Took about a week. No muss, no fuss, completely shocked, I didn't have to play games. The truck...
Mine has the hood/fender problem and the bed is skewed on mine. A half inch gap on one side almost nothing on the other. Looks terrible. 1st oil change they'll be getting an earful.
