• Heavy-duty cam and roller design low reverse one-way clutch for improved reliability
• New 4C billet spring retainer for increased strength and durability
• Steel girdle added to 2C piston allowing for more clutches and a broader apply area
• BD durable QT100 pressure plates that increase clutch counts and reduce deflection and distortion within the clutch drum
• Increased clutch count to handle higher torque levels: Over Drive +17%, Under Drive +20%, 2C +33%
• BD reinforced accumulator plate for enhanced durability under heavy use
• TCC limit valve machined and sleeved to address high wear areas within the pump
• BD Deep sump oil pan adds extra fluid capacity and improved cooling while reducing case flex
• BD ProTech68 pressure control module ramps line pressure up to 250 psi using MAP sensor input to optimize pressure based on load

Construction & Design

The BD Diesel 68RFE Transmission 4WD is built with premium materials and precision engineering to withstand the rigors of heavy-duty diesel applications. The valve body is hard anodized to resist corrosion and wear, while the billet spring retainer and steel girdle reinforce critical components to prevent premature failure. The QT100 pressure plates are designed to minimize clutch drum distortion, ensuring consistent clutch engagement and longer service life. The deep sump oil pan not only increases fluid capacity for better cooling but also reduces case flex, contributing to overall transmission stability.
