This transmission package corrects the most common failure points of the stock Ford 10R80, including harsh shifting, shift flares, and the leaking CDF clutch drum. It's engineered for greater reliability and longevity in stock or lightly modified trucks. — The BD RoadMaster directly addresses several known weaknesses in the OEM 10R80 transmission. Key upgrades include: — • Leaking CDF Drum: A revised CDF drum is installed with a new retaining feature. This prevents the common sleeve displacement issue that causes pressure loss, leading to long shift delays and burnt clutches. • Valve Body Failure: A brand-new, modified valve body increases line pressure by approximately 30%. This provides greater clutch holding capacity, resulting in faster, more decisive shifts and preventing premature clutch wear. • Torque Converter Shudder: The included BD ProForce torque converter is remanufactured with all-new, upgraded friction material to ensure smooth and reliable lock-up performance. • Heat Management: A deep sump transmission pan is included, which increases fluid capacity by 2 quarts. This extra fluid helps dissipate heat more effectively, extending the life of the transmission fluid and internal components.
