The BD Diesel 6R140 Transmission & Converter Package is engineered for heavy-duty Ford applications, specifically designed to enhance durability and performance for 2011-2016 Ford F-250 Super Duty trucks with 6.7L Power Stroke engines. This package includes a dyno-tested transmission and a high-capacity torque converter, ensuring reliable power transfer under severe towing and demanding driving conditions. The transmission features a BD Heavy Duty pan that increases fluid capacity, promoting better cooling and longevity during extended heavy-duty use.
The transmission incorporates custom BD patented pressure plates that increase clutch count without compromising part strength, providing increased torque capacity and improved shift quality. An upgraded, tig-welded input shaft prevents OEM weld failures, ensuring the assembly withstands higher torque loads. The design includes a four-surface clutch assembly that doubles the OEM friction area, along with an increased clutch count across the intermediate, overdrive, forward, and direct clutches, significantly enhancing holding power and durability. An electronic line pressure controller allows for up to 300 psi line pressure at wide-open throttle, optimizing clutch engagement and overall transmission efficiency.
The included torque converter is ideal for heavy towing, high horsepower applications, and aggressive driving, delivering consistent power transfer without creating parasitic load or excess heat when inactive. All components are constructed with billet aluminum and steel to handle increased power and thermal stress, ensuring long-term reliability. This transmission and converter package is a comprehensive upgrade designed to meet the rigorous demands of fleet, towing, and performance use, providing peace of mind through increased clutch engagement, heat dissipation, and overall drivetrain resilience.
Features:
- Heavy-duty transmission with increased clutch capacity for high torque applications
