The BD Diesel 1064194BF transmission upgrade kit is engineered to enhance durability and performance for heavy-duty Dodge Ram trucks equipped with the 47RE transmission. This comprehensive assembly features a billet input shaft designed to withstand the stresses of rapid throttle inputs and high horsepower applications, offering improved responsiveness and longevity. The kit includes upgraded internal components such as heavy-duty clutches with up to 25% more material, a machined beveled pressure plate, and a reinforced overdrive brake pressure plate, all aimed at supporting increased torque capacity and reliable operation under severe towing conditions.
Enhanced lubrication features such as drilled intermediate shafts and a BD auxiliary full flow filter kit ensure proper cooling and oil flow throughout the transmission, reducing heat build-up and extending component life. The pan has been redesigned with heat-dissipating fins and added capacity to maintain optimal operating temperatures, while the case saver reduces internal case flex and oil leakage. Upgraded governor pressure transducers and solenoids provide more precise control, allowing for up to 80% higher clutch apply pressures that begin at lower engine RPMs, resulting in firmer, more consistent shifts without shuttle shifting issues. Every transmission is dyno tested to verify performance and reliability, and the entire assembly is built to handle up to 300% more power and torque than stock units.
This transmission kit also features a durable aluminum heavy-duty pan with a magnetic drain plug, ensuring long-term drivetrain stability. The inclusion of a Billet dual ring accumulator piston, billet band strut, and a high-temp Raybestos band further contribute to the robust design, making it suitable for demanding fleet and towing applications. Note that use of third-party or OEM converters may affect warranty coverage. Designed for easy installation, this kit represents a significant upgrade for those seeking increased power handling, thermal management, and drivetrain resilience in their Dodge Ram 2500 or 3500 truck.
