A method of establishing a shift point for shifting an automatic transmission in a powered vehicle during a full throttle shift from a first gear ratio to a second gear ratio, the transmission having a controller, comprising: receiving torque data from a data bus electrically coupled to the controller, the torque data including a maximum torque value; converting the torque data to power data; calculating a gear step value based on the first gear ratio and second gear ratio; determining a first speed value and first power value based on the power data; computing a second speed value based on the gear step value; determining a second power value based on the second speed value; and comparing the first power value and the second power value to one another; and setting the shift point based on the result of comparing the first power value and the second power value.
