Abstract
Methods and systems are provided for operating a driveline of a four wheel drive vehicle that includes a high gear ratio and a low gear ratio. The driveline may be operated to shift between the high gear ratio and the low gear ratio while the four wheel drive vehicle is moving. In one example, a clutch is opened during shifting from the high gear ratio to the low gear ratio, which allows the vehicle to continue traveling during the gear ratio change.
