Abstract
Methods and system are described for changing a gear ratio of an axle gearbox that does not include friction clutches and that may or may not include synchronizers. The axle gearbox may receive propulsive force via an electric machine. The methods and systems permit the axle gearbox to be shifted from a high gear range to a low gear range while a vehicle that includes the axle gearbox is moving.
