New from American Powertrain – the Pro-Fit 6-Speed System for 1968-82 C3 Corvettes. This complete kit is built for easy installation for smooth as silk shifts. See more details below.
American Powertrain, the world’s largest TREMEC dealer, is now introducing the next generation Pro-Fit 6-speed system for 1968-82 C3 Corvettes. The system looks like the original 4-speed transmission with the correct shifter position in the factory console.
Designed as a complete kit, it features an American Powertrain customized TREMEC® MAGNUM 6-speed transmission that offers a choice of four different gear ratio combinations; all that will shift smooth as silk, a new crossmember, driveshaft, trans mount, offset shifter mechanism, calibrated speedo drive, Speedo cable, reverse light harness, 6-speed shift pattern plate, and mounting hardware. The transmission is rated at 700 lb./ft. and will shift up to 7,000 RPM.
American Powertrain’s DOM steel driveshaft, built with an exclusive billet face flange yoke, will make installation a five minute job, even in the narrow tunnel of a classic Vette. Options are available to upgrade to an aluminum, chromoly or carbon fiber driveshaft.
The price for the 6-speed Pro-Fit Kit for C3 Corvettes starts at $4,395, transmission included. Bellhousing is sold separately. All Pro-Fit kits are covered by American Powertrain’s two year warranty and includes free extended hours tech support.
