Precision Engineering & Unmatched Durability

SunCoast has taken the already robust 6R140 platform and reinforced it with upgraded clutch and steel recipes to significantly improve durability and performance. The new pump bushing addresses a well-known failure point, ensuring consistent fluid pressure and preventing premature wear. A high-quality filter, complete overhaul kit, and precision-engineered gaskets are included, making installation hassle-free.

Guardian Torque Converter – Unrivaled Efficiency and Power Delivery

Included with this transmission is the SunCoast Guardian Torque Converter, which is designed to outperform the stock unit in every way. Featuring an exclusive long-travel, high-capacity turbine damper, this converter minimizes drivetrain shock and optimizes power transfer for better throttle response and efficiency. SunCoast’s precision machining and enhanced stall speed options ensure that your truck pulls harder, shifts smoother, and lasts longer, even under the most demanding conditions. If you want to eliminate torque loss and improve durability, this is the converter your Powerstroke deserves.
