The Ford 6R140 platform was developed and constructed by Ford Motor Company. The 6R140 transmission is renowned for its durability and performance, featuring a deep first gear (3.97:1), double overdrive, and a one-piece deep skirt case. Ford added Sinter-brazed gear carriers and a dual media filter to extend service intervals up to 150,000 miles. Additionally, the 6R140 Transmission includes an integrated live PTO with a higher torque capacity than its Allison counterpart, while weighing 25lbs less.

However, there's a chronic issue with the Ford 6R140. Captive clutch failure is common and difficult to address with stock components or traditional methods. Unlike most lockup converters, the 6R140 clutch moves away from the engine block and engages a thin stamped steel backing plate, which is prone to flex and causes clutch failure. SunCoast offers a solution by using a custom rigid backing plate that reduces deflection, improving apply conformity and providing a more durable reaction surface than OE, improving longevity and reliability for years to come.

Another weak point is the OE clutch, which is held together by small, weak leaf springs that are prone to breaking and causing the OE steel clutch plates to damage the cover splines. This problem is particularly frequent in heavy-duty trucks that put massive stress on converter components. SunCoast improves the factory spring system on this 6R140 torque converter with a much more robust system, while also utilizing their ZERO-DRAG technology.

If you're a customer who does a lot of heavy towing or works out of their vehicle, then this new 6R140 torque converter is a perfect replacement for you. It prioritizes reliability, making it an ideal choice for those who need a durable and dependable transmission.
