Abstract: A floor mounted shift control mechanism for a vehicle wherein adjustment of each of the cables from the transmission and the key cylinder can be made inside the vehicle within the shift control mechanism. The shift control mechanism also includes provisions for locking the shift lever in its Park position when the key cylinder is in its Lock or Accessory positions; and for preventing the ignition key from being removed from the key cylinder unless the shift lever is in its Park position. There are also included provisions for requiring a high force to override the Locked-in Park condition, while operationally subjecting the cable from the key cylinder to reduced loads; and for an assured detent feeling for the driver while shifting through the various shift positions.
