Hello. Im Big R. I have a 3rd gen '06 2500....with 33 x 12.50s i tow a 42' fifth wheel weighing in at 11,700 dry weight. 141,000 miles.
Tranny is starting to shutter shift between 2nd and 3rd gear during daily driving. But....does NOT do it when camper is hooked up!
Time for a rebuild kit or what?
Opinions welcomed!
