ABSTRACT:
Racing car transmission in which the reverse gear does not rotate when the car is travelling in the forward direction. The main shaft in this transmission has shortened splines that do not engage the reverse idler gear except when the transmission is shifted into reverse. Provision is made for a spring biased pin on the gear shift yoke to engage the detent on the reverse idler gear hub to stop it from spinning when this gear is not in the engaged position. This improvement eliminates unnecessary rotational inertia when the vehicle is travelling in the forward direction thus eliminating unwanted inertia which saps power and speed from the engine. The improvement adds significantly to the available power of the engine.
