Gearboxes

Porsche transmissions, like their engines, are precision equipment, requiring extensive knowledge and expertise to repair and rebuild. DeMan Motorsport has the expertise to totally rebuild your tranny or make the necessary repairs. We have the factory tools to set the ring and pinion and handle any transmission job, large or small, be it a 901 or a late-model cable-shifter.

Factory and custom transmissions are rebuilt and bench tested. Performance analysis of the racecar is simulated to select gear ratios that provide the highest level of on track performance.
