BD Diesel 11-14 Ford 6.7L 6R140 Stage 4 Transmission and Converter Package

BD Diesel has been building robust drivetrain components for decades, and this Stage 4 Transmission and Converter Package for your 2011-2016 Ford F-250 Super Duty is one of their staples. If you're pushing your 6.7L Power Stroke hard, whether for towing heavy loads or for track use, the stock transmission might be struggling to keep up. This package is designed to handle significantly more power and torque, offering a dependable upgrade for demanding applications.

This isn't just a transmission; it's a matched set, dyno-tested together for optimal performance and reliability. BD Diesel has increased the clutch count in key areas: 8 clutches in the Intermediate (a 60% increase over stock), 8 in the Overdrive (14% increase), 6 in the Forward (20% increase), and 6 in the Direct (20% increase). These custom BD patented pressure plates allow for more clutches without compromising part strength. The included Electronic Line Pressure Controller can deliver up to 300psi of line pressure at wide-open throttle, providing a theoretical 76% more holding power than stock. A machined steel reaction ring replaces the factory's flexible stamping for improved durability. The torque converter is furnace-brazed for strength and is an ideal replacement for a tired stock unit. This package also includes BD's heavy-duty pan, which adds extra fluid capacity, helping to keep temperatures down during strenuous use.

When you purchase this BD Diesel transmission and torque converter package, you're getting a fully remanufactured unit built for long service life. The electronic pressure controller is only active when boost exceeds 15psi, meaning it doesn't create parasitic load or extra heat when you're just cruising. This setup is a great replacement for tired stock torque converters and is ideal for both street and towing applications where you need a transmission that can stand up to your diesel's power demands.
