BD Diesel 1064682SS Roadmaster Transmission Converter Package Ford Transit - 10R80 3.5L 2020-2024

The BD Diesel Roadmaster 10R80 Transmission and Converter Package delivers enhanced durability and performance for 2020-2024 Ford Transit vans equipped with the 3.5L engine (both EcoBoost and naturally aspirated V6). Engineered to address the known weaknesses of the factory 10R80 transmission, this complete assembly features critical upgrades that improve reliability and extend service life in stock or mildly modified applications.

Key Engineering Solutions:

• Revised CDF Drum: Eliminates the notorious OEM drum leak with a new retaining feature that prevents internal bushing shift and maintains proper fluid pathways
• Anodized Reaction Shell: Increased surface hardness prevents the embedded clutch tooth wear commonly found in stock 10R80 transmissions
• Modified OEM Valve Body: Brand new valve body with improved solenoid retention and 30% increased line pressure for superior clutch holding power and crisp, responsive shifts
• BD ProForce Torque Converter: Features updated friction material for improved power transfer and durability
• Premium Internal Components: New OEM clutches and steels throughout for reliable operation

Performance Benefits: Expect smooth, quick shifts without the long delays or shift flares caused by the leaking CDF drum in stock transmissions. The increased line pressure ensures positive clutch engagement under load, while the upgraded internal components provide peace of mind for daily driving and towing applications.
