ABSTRACT:
A vehicle performance sensor that monitors the operation of a vehicle and provides a shift point indicator to inform the vehicle operator when to shift the transmission. When the rotational output from the vehicle torque converter is not within the desired operating range of the transmission gearing, a signal will be generated to notify the operator by a visual indication that the transmission should be shifted and which gear should be selected.
