# BD Diesel 20-24 Ford Transit 3.5L 4WD Roadmaster 10R80 Transmission & Converter Package

Engineered for enhanced reliability and extended service life, the BD 10R80 RoadMaster Transmission is the ideal upgrade for stock or mildly modified trucks. It addresses common 10R80 weaknesses with durable solutions -- most notably, the notorious CDF Drum leak is fixed by introducing a retaining feature to support the internal bushing from shifting and blocking fluid pathways. For sharp shifts and lasting performance, each transmission features an anodized reaction shell to eliminate embedded clutch tooth wear issues and a new OEM valve body -- modified to improve solenoid retention and increase line pressure by 30%, delivering noticeably higher clutch holding power.

-   Brand new modified valve body to increase line pressure by approx. 30% for improved clutch holding
-   Updated anodized reaction shell for increased hardness corrects tooth wear issue common on 10R80s
-   Revised CDF drum with retaining feature to prevent sleeve failure common on OEM units
-   Will not have to worry about long shift delays or flares due to the leaking CDF drum
-   ProForce Torque Converter with new friction material
-   New OEM clutches and steels
-   Smooth and quick shifts
