The BD Diesel 1064682SS Roadmaster Transmission & Converter Package is the ideal solution for 2020–2024 Ford Transit 3.5L 2WD vans, whether naturally aspirated or EcoBoost. Designed to eliminate common failures associated with the 10R80 transmission, this complete package increases reliability, shift quality, and long-term durability for fleet and commercial applications.
BD addresses two of the most common factory weak points—CDF drum leaks and reaction shell tooth wear—by adding a retaining feature to the drum and using an anodized hardened shell. The modified valve body increases line pressure by ~30%, improving clutch holding under load. Matched with a ProForce torque converter and new OEM clutches, this package ensures smooth, crisp shifts and dependable operation mile after mile.
