Abstract: A transmission for a race car or other high performance vehicle includes a top mounted shift lever which has a remote location displaced rearwardly from the standard position directly above the gearbox. The shift lever can be mounted to either side of the gearbox to provide sufficient room and allowing the driver to be stationed away from the door for enhanced safety at the right side mounting position. A novel interlock mechanism is located in the transmission between the shift forks to provide a more compact arrangement and improved reliability.
