kit form maybe... depending. it isn't like you would want the car to slow down to 30 in a 70!
When I was towing the 31 the truck would obviously not like going up hills and of course downshift then roar to try to keep the same speed. I always slowed down heading up hills because if not, you might as well pour the gas out the window.
Exactly! I can't stand it when my RV downshifts to climb a hill. I would rather it slow from 65 to 55 like the heavily loaded trucks do anyway. This way, I'll have a knob on the dash that I can limit maximum throttle and keep it just off the kick-down switch but keep it rolling up a hill. Once back on the downside, the cruise control will maintain a controlled re-acceleration back up to the set speed and hold it there until the next hill.
