Product Description
The BD DIESEL 1064662SS Roadmaster Transmission and Converter Package is the ultimate reliability upgrade for 2018–2021 Ford Expedition and Lincoln Navigator equipped with the 3.5L EcoBoost and the factory 10R80 transmission (2WD). Designed for stock and mildly modified SUVs, this complete package corrects the most common 10R80 failure points while delivering smoother shifting, stronger clutch holding power, and extended service life for daily driving, towing, and heavy-use conditions.
This Roadmaster package includes a matched performance torque converter and internal upgrades engineered to resolve known factory weaknesses. The improved CDF drum design prevents bushing movement that can block fluid pathways and cause shift delays or flare conditions. A modified valve body increases line pressure for better clutch holding capacity, while updated hard parts help improve durability under load. Added fluid capacity and cooling support help keep clutch packs and steels cooler for longer-lasting performance.
