Abstract
The present invention provides a motor vehicle cold shift assist system for selectively and automatically connecting the non-driven wheels to its associated axle drive mechanism under certain operational and temperature conditions for counteracting the inertial loading acting on the transfer case synchronizer clutch mechanism. The present invention substantially reduces the shift resistance encountered upon the vehicle operator subsequently shifting into the four-wheel drive mode during cold weather conditions.
