ABSTRACT:
An apparatus for indicating an optimum time to shift a manual transmission in a vehicle. An electronic control unit is provided to compare the actual gear shift position with the electronically memorized optimum gear shift position. The optimum gear shift position is predetermined by examining the parameters of engine speed, vehicle speed, engine load and engine temperature. If the actual gear shift position differs from the memorized and stored optimum gear shift position, the operator is notified by a shift indicator lamp or loudspeaker.
