A method of controlling a transmission includes determining if an internal combustion engine of the vehicle is currently operating with active fuel management, or if the internal combustion engine is currently operating without active fuel management. The vehicle controller further determines if a possible engine torque is equal to, greater than, or less than a required engine torque. The transmission is upshifted when the internal combustion engine is currently operating with active fuel management, and when the possible engine torque is equal to or greater than the required engine torque. When the possible engine torque is less than the required engine torque, active fuel management is exited so that the internal combustion engine is currently operating without active fuel management. When the internal combustion engine is currently operating without active fuel management, the vehicle controller upshifts the transmission from the current gear ratio to the higher gear ratio.
