This BD Diesel 1064494SM transmission and converter package is designed for heavy-duty Ford F-250 Super Duty trucks from 2008 to 2010 equipped with the 6.4L engine. Built for durability and high performance, this complete upgrade combines a reinforced transmission with an enhanced torque converter to meet the demands of towing, fleet operations, and high horsepower applications. The transmission features increased line pressure, upgraded clutch counts, and heavy-duty components such as billet input shafts and billet band struts, ensuring improved strength and longevity under severe workload. The inclusion of a BD aluminum deep transmission pan adds an extra 6 quarts of oil capacity, aiding in heat dissipation and maintaining optimal operating temperatures, while the heat-dissipating fins further enhance cooling efficiency. Every transmission is dyno tested to ensure reliability before installation.
The torque converter is engineered with an enhanced stall to improve street and towing performance, providing a lower RPM response and more efficient operation. Cast aluminum stators multiply torque effectively, reducing stress on drivetrain components during heavy loads. The package also includes a full-flow auxiliary filter for extra protection, a high-performance Raybestos band, and a magnetic drain plug for ease of maintenance. The design incorporates improved lubrication and cooling features, such as a reworked front pump and furnace-brazed fins, which help reduce heat and prevent slippage. Built with high-yield strength forged pistons and multiple clutch surfaces, this system offers superior durability, capable of handling increased torque and shock loads.
Suitable for demanding fleet and automotive applications, this transmission and converter package is an essential upgrade for owners seeking maximum performance and reliability from their Ford F-250 Super Duty trucks. It is backed by a 36-month or 150,000-mile warranty on parts, and a 12-month or 24,000-mile warranty on labor, ensuring peace of mind. Installation should adhere to manufacturer guidelines, especially regarding break-in procedures, to preserve the integrity of the upgrades and achieve optimal performance.
