Abstract: An electric shift apparatus for a motor vehicle transmission in which the control means for the transmission includes a key card which must be inserted into a receptacle submodule of the control means to enable operation of the transmission and/or to enable starting of the vehicle engine. The key card includes a plurality of push button membrane switches corresponding to the various shift positions of the transmission as well as a magnetic strip containing the unique identifying code of the vehicle. Insertion of the key card into the receptacle submodule allows the magnetic code to be identified as the proper code for that particular vehicle, whereby to allow starting of the vehicle engine, and further enables the transmission of the vehicle so that selective depression of the various push button switches provided on the key card shifts the transmission to respective positions corresponding to the selected switches.

Abstract: A dust shield for a disc brake according to the present disclosure has an arcuate portion positioned adjacent an annular braking surface of a disc brake rotor. The arcuate portion of the shield has a plurality of ventilation holes with an annular lip at the periphery of each hole. A plate extends across the arcuate shield portion and is spaced apart from the annular lips. The dust shield permits air to flow about the rotor for cooling purposes while reducing the contamination of the braking surfaces of the rotor by dirt particles carried by splashed road water and air.
