Abstract: A new anti-theft system for permitting removal of the gear selection shaft from a vehicle having a gear selection console with an aperture extending through it that permits external gear selection of a transmission, thereby preventing theft of the vehicle. The inventive device includes a transmission engaging lever that is movably mounted to a transmission. The first end of the transmission engaging lever is insertable into the lower end of a shaft member that extends through the aperture in the console. A release lever extends from the aperture of the shaft member towards the lower end of the shaft member. The second end of the release lever has a flange extending from it that is inserted into a notch in the transmission engaging lever when the release lever is in an engaged position, thereby coupling the shaft member to the transmission engaging lever.
