Abstract
A vehicle gearbox has a rotatable actuator shaft having forward, neutral and reverse positions corresponding to forward, neutral and reverse operational modes of the gearbox. A control mechanism includes a first control lever operatively coupled to the actuator shaft for selecting a forward, neutral or reverse mode of the gearbox, a locking lever operable to actuate a parking lock, a second control lever coupled to the locking lever to control engagement and disengagement of the parking lock, and a device responsive to the second control lever for placing the gearbox in neutral when the parking lock is engaged. The device includes an actuator lever non-rotatably fixed to and extending radially from the actuator shaft and linkages coupled between the locking lever and the actuator lever for moving the actuator shaft into its neutral position when the parking lock is engaged.
