ABSTRACT:
An overdrive mechanism having offset input and output shafts permits a motor vehicle to be operated in an overdrive gear in a two wheel drive mode. A lockout prevents concurrent operation of the vehicle in overdrive and four wheel drive. The overdrive is arranged to reduce the magnitude of cyclic loading in single cardan universal joints transmitting engine torque through an angle.
