The BD Diesel transmission kit for 1998.5-1999 Dodge Ram 2500 and 3500 with 47RE 4WD offers a comprehensive upgrade designed for heavy-duty performance and durability. This Stage 4 package features a fully remanufactured transmission with high-performance components, including an upgraded valve body, a high-capacity torque converter, and reinforced internal parts to withstand demanding towing, hauling, and horsepower increases. The kit is engineered with precision-machined pistons, heavy-duty springs, and a stamp-forged steel front cover to optimize engagement and longevity under severe conditions. The enhanced stall converter lowers rpm response for better street and towing performance, while the upgraded governor pressure transducer and increased line pressure of 190-200 psi ensure consistent shift quality and improved fluid flow.
The transmission pan is constructed from billet aluminum, providing an extra 2 quarts of oil capacity and equipped with heat-dissipating fins that help maintain optimal operating temperatures under heavy loads. Additional features include a magnetic drain plug for debris collection, a BD auxiliary full flow filter kit for extra protection, and a cooler line case saver to prevent damage during extreme towing. The internal components, such as the billet band lever, billet band strut, and furnace-brazed fins, are designed to withstand high thermal and mechanical stress, ensuring long-term reliability. Every transmission is thoroughly tested on a dynamometer to verify performance before installation.
This upgrade not only improves torque capacity and shift smoothness but also enhances overall drivetrain durability, making it suitable for demanding fleet and performance applications. The kit also includes an upgraded governor solenoid, drilled intermediate shaft for increased lubrication, and a high-temp Raybestos band for consistent operation. Designed for ease of installation, it requires no race or sled pull use and comes with a 36-month/150,000-mile parts warranty and a 12-month/24,000-mile labor warranty, providing peace of mind for heavy-duty users.
