Description

Captive clutch failure in the Ford 2011-2019's 6R140 is a chronic problem. SunCoast addresses this by using a custom rigid backing plate that reduces deflection, improving apply conformity and durability. The OE clutch's weak leaf springs often cause failure; SunCoast's Category 1 converter is built for heat management and proper clutch engagement, ideal for heavy towing and demanding work. This process provides a more durable reaction surface than OE, improving longevity and reliability for years to come.
