21-24 Ford F-150 3.5L & 2.7L / 22-24 Navigator/Expedition 4WD BD Diesel 1064674SS Roadmaster 10R80 Transmission & Converter Package

21–24 Ford F‑150 3.5L & 2.7L / 22–24 Expedition / Navigator 4WD BD Diesel RoadMaster 10R80 Transmission & Converter Package – 1064674SS

This premium RoadMaster 10R80 Transmission & Converter Package, part number 1064674SS, is engineered to dramatically improve the reliability, performance, and service life of capable Ford trucks and SUVs. Designed specifically for 2021‑2024 4WD F‑150 models with 3.5L and 2.7L EcoBoost engines, and 2022‑2024 4WD Ford Expedition and Lincoln Navigator with 3.5L EcoBoost, this complete kit solves the most common failure points in the original 10‑speed transmission while offering smoother, firmer shifts and enhanced cooling. With a factory valve body increased line pressure by ~30%, a ProForce torque converter using advanced friction material, a deep‑sump pan for extra capacity, and reinforced internal components, the package unlocks the full potential of the powertrain for towing, hauling, or performance applications. It is compatible with Park‑By‑Wire shifters and allows optional temperature sensor integration for monitoring.

Key Features

• Modified valve body design boosting line pressure by approximately 30% for stronger clutch holding power.

• ProForce torque converter with upgraded friction material for firm, responsive engagement. 

• Deep‑sump oil pan increasing fluid capacity by ~2 quarts to reduce operating temperature and extend fluid life.

• Revised CDF drum with internal retaining sleeve to prevent the common OEM failure.

• Anodized reaction shell increases hardness to correct clutch tooth wear issues.

• New OEM clutches and steels for durable rebuild quality.

• Smooth, quick shifting performance with reduced flares or delay. 

• Easy to service via integrated fluid drain plug; temperature sensor port included. 

• Full compatibility with fold‑away Park‑By‑Wire shifter systems.
