RE: Ram 2500 with 4.10 gears--tach at 70mph?
Well, my 4 spd auto tranny if I remember right at 70 mph I was running something like 2300 rpms and 75 was a tad over 2500 rpms. I have found the mileage is optimal in this range and once you go over 70 mph and 2500 rpms on the highway mileage falls off a tad.
