BD Diesel 1064662SS Roadmaster Transmission & Converter Package 10R80 Ford Expedition Lincoln Navigator

Engineered for enhanced reliability and extended service life, the BD Diesel Roadmaster 10R80 Transmission and Converter Package is the ideal upgrade for stock or mildly modified 2018-2021 Ford Expedition and Lincoln Navigator vehicles equipped with the 3.5L EcoBoost engine and 2WD configuration.

This comprehensive package addresses common 10R80 weaknesses with durable, engineered solutions. Most notably, the notorious CDF drum leak issue is permanently resolved through a revised drum design featuring a retaining feature that supports the internal bushing, preventing it from shifting and blocking critical fluid pathways.

Key Performance Upgrades:

• Brand new modified OEM valve body increases line pressure by 30% for significantly improved clutch holding power and shift quality
• Anodized reaction shell eliminates embedded clutch tooth wear issues for long-term durability
• Revised CDF drum with retaining feature prevents the sleeve failure common in OEM units
• New OEM clutches and steels for reliable performance
• BD ProForce 10R80 torque converter with new friction material for smooth power transfer
• High-capacity deep sump transmission oil pan adds 2 additional quarts of fluid capacity

Benefits of Increased Fluid Capacity:

The deep sump pan design helps regulate operating temperatures and extends fluid life by keeping clutches and steels cooler than stock configurations. The pan includes a convenient drain plug for easy fluid changes and provisions for adding a temperature sensor if desired.

Compatibility and Installation:

This package is designed for Park-By-Wire equipped vehicles (dial/button shifter). It does NOT fit Expedition/Navigator models with conventional shifter. Estimated installation time is 11.5 hours. Replaces OEM part numbers JL1Z-7000-C and JL1Z-7000-E (2WD applications).

Warranty Coverage:

• Parts: 24 months / 100,000 miles
• Labor: 12 months / 24,000 miles

Emissions Compliance:
