The BD Diesel 10R80 RoadMaster Transmission (Part # 1064664SS) is engineered to provide enhanced reliability and a longer service life for 2018 Ford Expedition and Lincoln Navigator models equipped with the 10R80 transmission. This upgrade addresses common factory weaknesses, notably fixing the notorious CDF Drum leak through a revised retaining feature that supports the internal bushing, preventing misalignment and fluid blockage. The transmission features an anodized reaction shell that reduces clutch tooth wear, ensuring consistent performance and durability. A new OEM valve body, modified to increase line pressure by approximately 30%, enhances clutch holding capacity for sharper, more responsive shifts. Included in the package is BD’s ProForce 10R80 Torque Converter, designed with new friction materials for smooth engagement and reliable torque transfer, along with a high-capacity Deep Sump Pan that adds two quarts of fluid capacity, helping to keep transmission components cooler and extending fluid life.
This transmission is designed with user convenience in mind, featuring a drain plug for easy fluid changes and the option to attach a temperature sensor for monitoring operating conditions. The revised CDF drum prevents common sleeve failures associated with OEM units, eliminating long shift delays and flare issues caused by fluid leaks. The increased fluid capacity improves temperature regulation, which is critical under demanding towing or high-performance conditions. Compatibility with Park-By-Wire (dial or button shifter) systems makes this transmission suitable for modern vehicle setups, and it comes with all new OEM clutches and steels to ensure maximum performance.
Whether you’re restoring a fleet vehicle or upgrading a personal vehicle for heavy-duty use, the BD Diesel RoadMaster Transmission offers a robust solution built to meet the demands of severe towing, fleet duty, and power-enhanced applications. Its comprehensive features and durable construction make it a reliable choice for extending vehicle longevity and improving driving experience under challenging conditions.
