American Powertrain Announces New Pro-Fit 6-Speed System for 1968-82 C3 Corvettes

System includes TREMEC® MAGNUM transmission 

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 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 holds 700 lb./ft. and will shift at 7,000 RPM!

American Powertrain’s DOM steel driveshaft, built with an exclusive billet face flange yoke, will make driveshaft 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.

    1. We sell the TREMEC Magnum 6-speeds. They are rated at 700ft/lbs with a 2 year warranty. They can tons of abuse and shift very smooth. You will have to make some tunnel mods to fit this into a 54. We also sell a bolt in 5-speed kit that does not require as much modification. Give us a call at 931-646-4836 for more info and customized quote.
