do I keep it or do I disable it?
when going down a hill and the van senses that its on any kind of grade it downshifts and spins up the tranny to help slow you down. keep it or not?
yeah but it only slows down 2 tires. so will have to see if it works for me in the winter.Besides saving your brakes, downshifting down-hill under snowy/icy conditions lessens the reliance on your brakes alone, especially with the added weight of equipment, and will allow for a smoother brake game, and will lessen the chances of losing control due to by braking too hard or too erratically.
Personally, I am not sure I would want a computer fooking with my gears during slick winter conditions.
Lost art of winter driving.
