A method for shifting a transmission capable of operating in a hydrostatic power transmission mode or a blended hydrostatic and mechanical power transmission mode is provided. The transmission includes a mechanical portion and a hydraulic portion. The method comprises the steps of placing the transmission in the hydrostatic power transmission mode, reducing an amount of engagement of a primary clutch, adjusting a rotational speed of the hydraulic portion, increasing an amount of engagement of a secondary clutch, and engaging the secondary clutch and disengaging the primary clutch. The method for shifting the transmission minimizes torque interruption, increases a fuel efficiency of a vehicle, and increases a range of operating speeds of the vehicle the transmission is incorporated in.
