The BD Diesel 1064574SS Roadmaster Transmission & Converter Package is designed specifically for the 2021 Ford F-150 with the 3.0L Power Stroke Diesel engine and 4WD configuration. This package features a fully remanufactured transmission with a modified valve body that increases line pressure by approximately 30%, resulting in improved clutch holding capacity and enhanced overall durability. The transmission includes a revised CDF drum with a retaining feature that prevents common sleeve failures seen on OEM units, ensuring reliable operation under demanding conditions. The upgraded design eliminates long shift delays and flares caused by leaking CDF drums, providing smoother shifting performance and better drivability. An increased fluid capacity with the new Deep Sump Transmission Oil Pan adds an extra two quarts of fluid, aiding in temperature regulation and extending fluid life, which is critical for heavy-duty towing and performance applications. The package also includes a rebuilt stator for consistent operation and a fully remanufactured clutch assembly with new clutch material and low-friction bushings for reduced wear and improved engagement. The BD ProForce Torque Converter included is equipped with new OEM clutches and steels for smooth, quick shifts, enhancing overall transmission responsiveness. Designed for heavy-duty fleet and towing use, this assembly offers a robust upgrade over stock components, ensuring long-term reliability and performance in severe operating conditions. Proper installation and adherence to recommended break-in procedures are essential to maximize the lifespan of this high-performance transmission system, especially in demanding diesel applications. This product is ideal for fleet operators, diesel enthusiasts, and professional repair shops seeking a durable, factory-quality upgrade for their 2021 Ford F-150 with the 3.0L Power Stroke engine.
