Upgraded from the Inside Out – No Weak Links

SunCoast has meticulously redesigned critical components of the 6R140 to eliminate weak points and maximize performance. The reinforced 4-5-6 Overdrive Clutch Pack increases holding power, while the patented E-Clutch Hub Damper eliminates the common 3-4 gear “squawk” for crisp, silent shifts. The custom-machined Overdrive Apply Piston provides enhanced engagement, ensuring the transmission holds strong under heavy loads. Additionally, the factory pump is upgraded with a new high-performance pump bearing, addressing common lubrication failures that can lead to catastrophic damage. Built with premium carbon graphitic clutches, custom-machined steels, and an upgraded valve body, this transmission is designed for those who demand the best in strength, longevity, and reliability.

Torque Converter Excellence – More Holding Power, Less Slippage

Paired with the SunCoast 6R140 transmission is a high-performance billet torque converter, delivering exceptional power transfer, improved efficiency, and superior durability over stock. Designed to handle high torque loads, this converter features a long-travel, ultra-high-capacity turbine damper, ensuring smoother power delivery while reducing strain on internal components. With multiple stall speed options, it allows for precise tuning based on your truck’s performance needs. Unlike stock converters that can slip and create excessive heat under heavy loads, this billet triple-disc converter ensures efficient lockup, improved towing capability, and extended transmission life—making it the ultimate upgrade for hardworking Powerstroke owners.
