Have a 1500. I swapped the rear axle because it went bad. The old axle had 3.21 gear ratio. The replacement axle has 3.92 gear ratio. I know the truck has to be reprogrammed for the new gear ratio.
Am I causing any damage driving the truck "un-programmed" to mechanic to have it reprogrammed?
Thanks
Matt
