My grandpa has a 5.9 (2003) with the auto and its got well over 200,000 miles doing nothing but hauling campers and its still running perfect. It shifts a little rough when you get into it, but its a truck. IMO the 6 speed is just a better choice. I wish my truck (5.9 gas) had a 5 speed, because there are times goin up a hill at 75 and im runnin a good 2,000 rpms and it still decides to down shift. I think my truck may be stupid lol.
haha. mine does the same thing. I dont run CC anymore on the highway. I hate it when it downshifts when going up a hill. Id rather slow down rather than it shift.
