Abstract: A transmission shift control lever assembly includes a shift detent gate in which a portion of the shift lever is disposed. A latch member is pivotally mounted relative to the gate and is selectively positionable to open and close a path between a "Park" position and other operating positions. The latch is responsive to a spring, an electro-magnetic element or assembly, the lever and a bias spring to establish its position. A one-way device is disposed between the electro-magnet and the latch member such that the shift lever bias spring will urge the shift lever to pivot the latch member into the "Park" position even when the electro-magnet is operating to hold the latch member in the open position.
