A control apparatus for a transmission having a first gear ratio, a second gear ratio, and an output shaft is disclosed. The apparatus includes an actuator assembly which disengages the first gear ratio from the output shaft and engages the second gear ratio to the output shaft in response to an upshift signal. The apparatus further includes a memory device which stores a conservative upshift point and an aggressive upshift point. The apparatus yet further includes a controller operable to read the aggressive shift point and the conservative shift point from the memory device. The controller is further operable to determine if the transmission is operating in a conservative mode of operation or operating in an aggressive mode of operation. The controller is yet further operable to generate the upshift signal at the aggressive upshift point if the transmission is operating in the aggressive mode of operation or generate the upshift signal at the conservative upshift point if the transmission is operating in the conservative mode of operation. A method of controlling a transmission assembly is also disclosed.
