Description

Designed for Ford 6R140 transmissions, this torque converter is suitable for heavy towing and work vehicles prioritizing reliability. Features include furnace-brazed fins, improved spring system, SunCoast ADCCT Anti-Drag Captured Clutch Technology, a new torque converter clutch, custom turbine/pump angle manipulation, a rigid backing plate to reduce deflection, and new Torrington thrust bearings. It is dynamically precision balanced and manufactured in Fort Walton Beach, Florida. It does not come with a billet cover as it's not deemed necessary for non-racing applications. Addresses common 6R140 issues like captive clutch failure and weak OE clutch springs.
