The present invention provides a method of selecting an economy mode shift schedule for a transmission coupled to a motor vehicle. The method includes calculating vehicle acceleration and determining a change in accelerator pedal position. Also, a net tractive effort force of the vehicle is determined for a current gear range of the transmission. Also, the method includes comparing the net tractive effort force for the current gear range to a maximum tractive effort force for a desired gear range and selecting the economy mode shift schedule for the transmission based on the comparison. The method further includes controlling shifting between one or more gear ranges of the transmission according to the economy mode shift schedule.
