BD Diesel Ford F250 2003-2004 6.0L 4wd 5R110 Transmission And Converter Package

If you're looking to significantly upgrade the drivetrain on your 2003-2004 Ford F-250 Super Duty with the 6.0L diesel engine and 4WD, this BD Diesel Stage 4 Transmission and Converter Package is a serious consideration. This isn't just a rebuild; it's a complete overhaul designed to handle more power and provide greater reliability, especially for towing and street use. It addresses common weak points in the stock 5R110 transmission, giving you peace of mind when you put your truck to work.

BD Diesel has reinforced this transmission with a host of upgrades. You'll find increased clutch counts across the board, including a notable 67% increase in the Intermediate and Overdrive clutches, and a 20% bump in the Direct clutches. They've replaced stock bushings with roller Torrington bearings and added a billet input shaft to better handle the 'snap' from rapid throttle changes and higher horsepower. The valve body has been modified for improved line pressure (190-200 psi) and includes a modified manual valve for better lubrication in all gear positions, eliminating shuttle shifting issues. The package also includes a heavy-duty aluminum pan that adds 6 quarts of extra oil capacity and features heat-dissipating fins to keep temperatures down, along with a magnetic drain plug and an auxiliary full-flow filter kit for added protection.

The included torque converter is also enhanced for street and towing applications, featuring a stamp-forged one-piece cover that resists warping from clutch heat and trapezoid teeth with a self-centering design for tighter tolerances, reduced wear, and less chatter. This matched set has been dyno-tested together to ensure optimal performance and reliability. BD Diesel backs this package with a 36-month/150,000-mile parts warranty and a 12-month/24,000-mile labor warranty, underscoring their confidence in its durability.
