Abstract
A transmission lock assembly (10) of the type for retaining a vehicle gear selector mechanism (20) in the park position until the vehicle brake pedal (54) is depressed. The assembly includes a first conduit (58) having a housing (60). The conduit (58) and housing (60) are adapted to be connected to a steering column (48) of the vehicle (12). A first core element (64) is slideably disposed in the conduit (58) and housing (60) and is connected to the gear selector mechanism (20). A block cam (70) is fixedly disposed on the first core element (64) and is moveable within the housing (60). A locking lever (76) engages the block cam (70) to prevent movement thereof in the locked condition. A release lever (86) is pivotally secured within the housing (60) and engages the locking lever (76) to move same between the locked and unlocked conditions. A second core element (90) is slideably supported by a second conduit (104) and interconnects the brake pedal (54) with the release lever (86). As the brake pedal (54) is depressed, the second core element (90) pivots the release lever (86) and thereby the locking lever (76) to move the locking lever (76) to the unlocked position and permit movement of the first core element (64).
