The Ford C6 transmission is a 3-speed longitudinal automatic transmission that was designed to be used in larger engines and handle more power and torque than the similarly designed Ford C4. The C6 transmission was the first transmission to incorporate a flexible shift band and used behind the 351 Cleveland and Ford 385 engines on a variety of vehicles including the Mustang, Thunderbird, Torino, and F-150s. Raybestos Powertrain provides the premium friction materials you need to build a reliable C6 transmission to get down the street, to the next car show, or down the drag strip.
