BD Diesel 1064664SS Roadmaster Transmission & Converter Package 10R80 Ford Expedition Lincoln Navigator 3.5L EcoBoost

Engineered for enhanced reliability and extended service life, the BD Diesel 1064664SS Roadmaster Transmission is the ideal upgrade for stock or mildly modified 2018-2021 Ford Expedition and Lincoln Navigator vehicles with the 3.5L EcoBoost engine and 4WD configuration.

This comprehensive package addresses common 10R80 weaknesses with durable, proven solutions. The notorious CDF drum leak is permanently fixed by introducing a retaining feature that supports the internal bushing, preventing it from shifting and blocking critical fluid pathways.

Key Components & Features:

• Brand new modified OEM valve body increases line pressure by 30% for dramatically improved clutch holding power
• BD ProForce 10R80 torque converter with new high-performance friction material
• Deep sump transmission oil pan adds 2 extra quarts of fluid capacity for superior cooling
• Revised CDF drum with retaining feature eliminates the sleeve failure common in OEM units

• New OEM clutches and steel plates for reliable performance
• Enhanced solenoid retention design for consistent operation
• Drain plug for easy fluid maintenance and optional temperature sensor port
• Park-By-Wire (dial/button shifter) compatible
