The BD Diesel 1064262SS transmission is a high-performance replacement designed specifically for heavy-duty diesel trucks such as the Dodge Ram 2500 models from 2007.5 through 2018, including 2WD configurations. This Stage 4 transmission includes a comprehensive ProForce converter package, engineered to deliver increased torque capacity and improved towing performance. The assembly features a durable QT100 pressure plate that reduces clutch deflection and distortion, ensuring consistent engagement under severe load conditions. Additionally, the custom bonded gasket valve body separator plate enhances line pressure and prevents internal cross leaks, promoting reliable operation over time.
The transmission’s deep sump oil pan adds extra fluid capacity and cooling efficiency, which is essential for maintaining optimal operating temperatures during heavy-duty towing or high-stress applications. Reinforced components such as the billet forged front cover with thicker walls and stronger mounting pads increase structural integrity, while the steel girdle on the 2C piston allows for more clutches and a broader apply area. The TCC limit valve has been machined and sleeved to address high-wear areas within the pump, further improving durability. Each unit is assembled with a hard anodized valve body and a new solenoid pack, ensuring precise control and longevity.
Furnaced brazed turbine fins improve fluid coupling efficiency, while the overdrive clutches and 2C clutches are increased by 33%, providing enhanced torque capacity for demanding applications. The heavy-duty cam and roller design low reverse one-way clutch, along with the high-performance stall stator and custom overdrive shaft, contribute to smoother shifts and better response at lower RPMs—ideal for street and towing use. This transmission is an excellent replacement for stock units, capable of handling up to 550 flywheel horsepower, with features designed to improve overall drivability and reliability in severe fleet or performance diesel applications.
Features:
- Heavy-duty diesel and fleet torque capacity for demanding towing and hauling
- Premium friction materials for smooth and consistent clutch engagement
- Enhanced thermal capacity to prevent clutch slippage under severe towing conditions
- Long-term drivetrain reliability through reinforced components and advanced design
