Abstract
A park-lock mechanism for a vehicle equipped with a transmission operatively controlled by a pair of shift levers. One of the shift levers is a range selector shift lever and the other is a gear speed shift lever. The park-lock mechanism is comprised of a spring-loaded capsule positioned on the range selector shift lever, and an interlocking mechanism which is mounted adjacent to both of the shift levers. The spring-loaded capsule provides a means for preloading the range selector shift lever into the park position only when the interlocking mechanism has the transmission positioned in its lowest gear speed.
