BD Diesel 18-21 Ford Expedition 3.5L Ecoboost 2WD Roadmaster 10R80 Transmission & Converter Package

Doing a transmission swap on your 2018-2021 Ford Expedition or Lincoln Navigator? This BD Diesel Roadmaster 10R80 Transmission and Converter Package is built to handle more than stock, addressing known weak points in the factory transmission for enhanced reliability and a more responsive feel. If you're looking to tow heavier loads or just want a more robust drivetrain for your 3.5L EcoBoost, this package offers a solid upgrade.

BD Diesel has reinforced this 10R80 transmission by tackling common failure points. They've revised the CDF drum with a retaining feature that stops the internal bushing from shifting, which can cause fluid leaks and performance issues in stock units. You'll also find an anodized reaction shell to prevent clutch tooth wear, and a new OEM valve body that's been modified to improve solenoid retention and increase line pressure by about 30%. This higher line pressure means the clutches can hold more power, leading to sharper shifts and better performance, especially when you're asking more from your engine.

This package includes BD Diesel's ProForce 10R80 Torque Converter and a high-capacity deep sump transmission pan. The deep pan adds an extra two quarts of fluid capacity, which is crucial for keeping temperatures down during demanding use, like towing or spirited driving. Cooler fluid means your transmission's clutches and steels will last longer. The torque converter itself features new friction material for improved engagement. This transmission is also compatible with park-by-wire systems, meaning it will work with your Expedition or Navigator's dial or button shifter.
