The much hated skud missile (low flying, poorly guided missle) AKA 78 Ford LTD II, would lock in second if you selected "D2." It was much appreciated by me a couple of winters. I was fairly broke, then, and being able to kill some torque on an icy intersection got me goin' more than once. My 04 Sierra also starts in 2 if that is selected, but there's been times that I've had it in "2" and tromped on it, it will kick into 1. Weird, that. It does not have "posi"
