I have a 98 Grand Marquis. I noticed that when you use "drive 2" on the gear s*it selector, the car starts out in second gear, and there is less torque to the rear wheels. This seems to work good for me when there are icy roads.
I had a 1965 Ford Galaxy that had the same type of arrangement with the transmission. Is this a patented thing with Ford? I have had GM cars and Chrysler and those cars had different speeds in the lower gears.
