ABSTRACT:
A transmission control for an engine of an automotive vehicle wherein the vehicle has a steering column assembly having a steering wheel unit pivoted to a rear end portion of a steering column for limited arcuate movement provided with a key-operated cylinder forming part of an ignition system for the engine. A gate is mounted on the steering column and has a plurality of spaced detents corresponding to the usual gearshift positions. A gearshift lever is movable relative to the gate and has a part selectively engageable in the detents. A gearshift blocker is supported on the steering column for pivotal movement to and from an operative position blocking movement of the gearshift lever away from the PARK position. A link is supported on the steering column for sliding movement in opposite directions and has a lost-motion pivotal connection to the blocker to pivot the blocker to its operative position when the link in slid in one direction and away from its operative position when the link in slid in the opposite direction. The link is moved in one direction by an arm pivoted on the steering wheel unit operated by an actuator on the key-operated cylinder. A head on the arm engages a head on the link. These heads are curved on an axis coinciding with the axis of pivotal movement of the steering wheel unit so that the blocker may be operated by operation of the key-operated cylinder in any angular position of the steering wheel unit.
