This invention is an electrical control apparatus for control of a transmission apparatus in a motor vehicle which provides safety features and improper operation indications. The transmission apparatus has a plurality of transmission states and at least one motor adapted for shifting between transmission states. According to a first aspect of the invention the input device is a plurality of momentary contact push buttons, and the logic control unit provides a priority of transmission state selection in accordance to a predetermined hierarchy of priority if more than one push button is depressed. In accordance with a second aspect of the invention, the electrical control apparatus provides a fault indication, such as via a lamp, if said desired transmission state differs from said present transmission state for longer than a predetermined period of time. In accordance with a third aspect of the present invention, the electronic control apparatus includes a vehicle speed sensor, and the logic control unit inhibits shifting the transmission and provides an error indication, such as by a lamp, if the speed of the vehicle is too fast for the desired gear.
