A floor mounted manually operable shifter assembly for use with a vehicle manual transmission having a gear shifter selectively pivotal to a plurality of positions about longitudinal and transverse axes. The gear shifter assembly base has a pivotally mounted bellcrank lever, including an upstanding first arm and a rearwardly extending dish-shaped second arm, defining an upwardly concave semi-spherical raceway formed with a reverse gear position notch. An end fitting, pivoted on the shifter lower end, is adapted to apply a clockwise pivoting force on the raceway during the shifter's rearward travel which force overrides an interlock cable core counter-clockwise biasing force on the bellcrank lever. During the end fitting's forward travel on the raceway the cable core biases the raceway into counterclockwise sliding contact with the end fitting. Upon the fitting being captured in the reverse gear notch, the bellcrank is at its forward limit position wherein rotation of an ignition lock cylinder to its key-release Lock mode results in the cable core locking the bellcrank lever, whereby the shifter end fitting is held in the reverse gear notch allowing the vehicle to be driven only in reverse gear.

Manual transmission shifter to ignition interlock

A shift control lever assembly for use with a transmission shift control mechanism, wherein the assembly includes a palm abutting knob housing an actuating assembly secured to an operating button extending from an end of the palm abutting knob. A push rod extends downwardly from the latter for actuating the shift control mechanism. A ramp is formed on the actuating assembly, and a ball is rotatably mounted at the top end of the push rod for cooperation with the ramp to urge the push rod downwardly upon manual depression of the operating button.

Shift control lever assembly

A vehicle park interlock system has a gearshift selector assembly coupled with an ignition locking slider receiving mechanism. The system prohibits the vehicle gearshift from being moved from a park position without the vehicle ignition mechanism being unlocked, e.g. in an off, on or start position.

Gearshift park interlock system

A vehicle park interlock system has a column mounted ignition pin locking slider receiving device adapted to couple with an ignition pin locking slider of the ignition system of the vehicle. The ignition pin locking slider receiving device is coupled with a gearshift selector assembly forming the system. The system prohibits the vehicle gearshift from being moved from a park position without the vehicle ignition mechanism being unlocked, e.g. in an off, on, or start position.

Ignition key locking device for gearshift park interlock system

A self-adjusting gear shift lever assembly serving as a link in the shift cable connection between the transmission and the shift lever providing a spring preload on the shift cable and fastener means for adjusting backlash and build tolerances in the shift cable. Two embodiments of the assembly each include a relatively rotatably interconnected lever member and clamp plate. One embodiment has a D-shaped opening formed in the clamp plate for being secured to the transmission shift shaft, with the fastener means on the clamp plate and pin means on the lever member for mounting the end of the shift cable, and a tension spring between the lever member and clamp plate. The other embodiment has the D-shaped opening formed in the lever member, with the fastener means on the lever member and the pin mounting means on the clamp plate, and a compression spring between the lever member and clamp plate.

Self-adjusting gear shift lever assembly

A shift lever mechanism for use with a vehicle automatic transmission. A pivoting lever supports an upwardly spring biased plunger for fore and aft travel in a detent slot. The detent slot is formed in a cylindrical plate portion formed substantially concentric with the transverse pivot axis of the lever. The plunger is made from plastic material and is formed with a pair of transverse wall portions each having a plurality of mirror image step-up blocks. The slot includes a series of interconnected notches having progressively decreasing widths in both its fore and aft directions from a central dual mode notch. The notches define locating edges which successively contact and position the upwardly biased plunger step-up blocks during either fore or aft travel from the central notch to define a plurality of modes for the transmission.
