Abstract
The present apparatus includes a park/lock mechanism mounted on a transmission for controlling operation of the transmission and, more particularly, for preventing the transmission from being shifted out of the park position until predetermined vehicle operating conditions are met. The park/lock mechanism is remotely actuated by an actuator physically connected to the park/lock mechanism and electrically connected to the shift lever. The park/lock mechanism includes a linkage having a pair of links connected in an overcenter arrangement, the toggle links providing a mechanical advantage and moving overcenter as the park/lock mechanism moves to a park/lock position. A hydraulic circuit and electrical circuit for operating the actuator is also disclosed.
