In the ATC position, truck system will shut engine rpm down if it senses a slip on any set of drive tires. It really limits your options at times of getting out of situations. We have a lot of ive and snow pack around right now. In the ATC position, once wheel slip is detected, engine goes to idle speed and that is all you got until slip is not detected. It does keep inexperienced drivers from doing stupid stuff like getting on a gravel road and trying to throw sand with spinning tires or spinning tires on ice trying to do a power slide.
I would think a twin screw with good tires and a good driver wouldn't have much to worry about. It will go in slick conditions as well as anything. Exceptions might be trying to get truck moving out of the field and to a good road at the start of a thunderstorm.
