The BD Diesel 1064174BF transmission upgrade is designed to optimize heavy-duty performance for Dodge Ram trucks equipped with the 47RE transmission, specifically for models from 1998 to 1999. This comprehensive kit features a billet input shaft engineered to withstand the demands of rapid throttle response and high horsepower applications, ensuring your drivetrain can handle increased torque and power without compromise. It includes a fully rollerized geartrain, upgraded clutches with up to 25% more material, and heavy-duty internal components to significantly enhance durability and long-term reliability in fleet and towing operations.
The transmission assembly incorporates a new design valve body, drilled intermediate shaft for superior lubrication, and an upgraded governor pressure transducer and solenoid, which provide increased line pressure—up to 200 psi—delivering more consistent clutch engagement and shift firmness. The addition of a high-capacity aluminum transmission pan with heat-dissipating fins reduces operating temperature and internal oil leakage, while the magnetic drain plug facilitates easier maintenance. Every unit is dyno-tested to ensure performance standards and comes with a 36-month/150,000-mile limited warranty, demonstrating confidence in its rugged performance.
This upgrade also features a BD auxiliary full flow filter for extra protection, along with a cooler line case saver to prevent internal damage. The revised oil circuits and reinforced internals allow handling of up to 300% more torque than stock, making this transmission a robust solution for high-power applications. Designed for easy installation, the kit is not intended for race or sled pull use and should be installed following manufacturer guidelines for optimal results. Whether for towing, heavy-duty work, or high-performance applications, this transmission assembly offers a significant upgrade over stock components, ensuring your vehicle maintains reliable operation under severe conditions.
