ABSTRACT:
A shift-up indicating system for manual speed change gears of an automobile transmission wherein preset values are respectively provided for the speed of the automobile, the engine speed of the engine and the vacuum pressure of the engine to determine a region of running conditions which can provide a good fuel consumption for every shift position of the speed change gears such that when a driver selects one of the predetermined gear positions of the speed change gears, if the condition of fuel consumption is brought out of the determined region, then an indication is given to the driver by an illuminating indicator to thereby urge the driver to shift up the speed change gears to a higher gear.
