Abstract
The present invention is a method and apparatus for locking a vehicle transmission where at least one directional clutch gear is located on one end of a shaft and a second directional clutch gear and a park flange are located at the other end of the shaft.

The transmission is locked when the single clutch is engaged with the park flange as the flange is secured to the transmission housing.
