BD Diesel Ford 4R100 Transmission & Converter Package 99-03 4wd c/w Filter Kit

If you're looking to significantly increase the durability and performance of your 1999-2003 Ford F-250 Super Duty's drivetrain, this BD Diesel 4R100 Transmission and Converter Package is a solid choice. This isn't just a stock replacement; it's a complete overhaul designed to handle the demands of your diesel truck, whether you're towing heavy loads or just cruising the street. The package includes a fully rebuilt transmission and a matched torque converter, both dyno-tested together to ensure they work seamlessly for optimal performance and reliability.

BD Diesel has re-calibrated the accumulator body for quicker, firmer shifts, and included a full shift kit with a line mod valve to increase line pressures. You'll also find added lube circuits for the overdrive planet, output shaft, and intermediate shaft, along with support for these critical components. To prevent leaks, the direct and intermediate feeds are drilled and tapped directly into the case. The transmission also features an upgraded overdrive snap ring, a machined center support, a reworked front pump, and a fully rollerized geartrain for improved longevity. The included heavy-duty aluminum deep pan adds an extra 6 quarts of oil capacity, which helps keep temperatures down during demanding use.

The included torque converter is built for enhanced stall, making it suitable for both street driving and towing applications. It features torque-multiplying cast aluminum stators for better low-rpm response than stock, leading to more efficient operation, less heat, and improved fuel economy. The converter also boasts a stamp-forged steel front cover and furnace-brazed fins for strength, along with up to triple the amount of lock-up clutch material for increased durability. This package comes with BD Diesel's own auxiliary frame-mounted full-flow filter kit, ensuring your transmission fluid stays clean. It's backed by a 36-month/150,000-mile parts warranty and a 12-month/24,000-mile labor warranty.
