The transmission is shifted to the target transmission gear ratio when it is determined that the vehicle speed is in an appropriate range. The transfer case input torque is reduced to a minimum value, and the transfer case is shifted to neutral. The method further includes adjusting the engine speed and transmission gear setting to control the transmission output shaft speed to a desired range. The transfer case is shifted from neutral to the desired transfer case range when the transmission output shaft speed is within the desired range of transmission output shaft speed. | ||||||
