The BD Diesel 1064514SS TowMaster Transmission & Converter Package is the ultimate bolt-in solution for 2017–2019 Ford Super Duty trucks running the 6.7L Power Stroke and 6R140 transmission. Built to conquer heavy towing, aggressive throttle, and high-demand applications, this package delivers unmatched durability, torque handling, and shift quality.

At the heart of the TowMaster system is BD’s enhanced clutch pack featuring up to 60% more clutch capacity in critical gear stages—thanks to BD's patented pressure plate design. A brand-new valve body and Electronic Line Pressure Controller ramp up pressure to 300 PSI at wide-open throttle, ensuring smooth, firm shifts under load without excessive heat buildup. Paired with a remanufactured torque converter featuring a dual-surface clutch, furnace-brazed fins, and a machined steel reaction ring, this combo is purpose-built for hard-working trucks.
