Abstract
In a transmission control apparatus for an automotive vehicle having a shift lever, a controller and a transmission actuator, a shift operation detector is additionally connected between the controller and the transmission actuator to apply an actuator control signal to the transmission actuator only when the shift lever is being operated, thus preventing erroneous operation of the transmission due to external noise. The shift operation detector comprises a touch switch provided on the shift lever knob so as to be closed only when the driver grips the knob and a hold relay energized by the actuator control signal applied from the controller via the closed touch switch.
