Well thanks again, all for your input, I suspect it has something to do with the 3.42. I talked to my friend again and he also told me he had it on cruise control and on every hill the truck would kick down and rev up to maintain speed up the hills, on the same strech of highway my truck will go up most all of the same hills without doing this so I suspect my truck has different ratio rear end and although it may be higher Ie. 3.73 it does in fact suit the vehicle better and may give it better gas mileage vs. the 3.42 which you would think at least at first glance would be better on gas but Chevy does rate the 3.73 models higher in gas mileage than the 3.42. I will stop now as i am confusing myself
