Thumbnail Filmstrip of 6.7 Powerstroke Cat 1 10R140 Rebuild Kit Suncoast SC-10R140-CAT1RD Images
When the powerful 2018-2024 6.7 Powerstroke in your Ford Super Duty demands peak performance and efficiency, a robust transmission is non-negotiable. The Ford 10R140 10-speed automatic transmission, co-developed to meet stringent government mandates, represents a leap forward in gearbox technology. It was engineered to capture the seamless efficiency benefits of a continuously variable transmission (CVT) while retaining the familiar, high-performance feel of a geared automatic. This is achieved through a wide 7.39 gear ratio spread that includes a low 4.70 first gear for maximum launch power and three overdrive gears for effortless cruising. Crucially, the 10R140 features extremely small steps between its ten ratios—the engine RPM only drops approximately 20% with each shift. This precision keeps your engine in its ideal powerband, maximizing performance for narrow power applications like large camshafts in naturally aspirated setups, or optimizing for larger turbos and AR housings in forced induction environments. Give your transmission the foundation it needs to master its advanced design with the Suncoast SC-10R140-CAT1RD Cat 1 10R140 Rebuild Kit.
- Stock Clutch Counts, Complete Module: This is a complete clutch and steel module kit containing all the necessary stock count frictions and steels for a full rebuild of your 10R140 transmission.
- Raybestos GPZ Friction Plates: Far exceeding OE material, these high-performance plates are engineered for greater torque capacity, higher heat resistance, and up to 20% better durability than stock, ensuring enhanced shift feel and long-term reliability under high-stress, heavy-duty conditions.
- Factory OEM Filter with Newly Designed Thermal Flow Control: The kit includes the new factory filter featuring a sophisticated two-media (fine and coarse) filtration system. At startup, fluid flows through both; as the fluid heats up and viscosity drops, an internal thermal plate restricts the coarse media, directing flow primarily through the fine media for superior filtration of finer debris.
- High Performance Overhaul Kit: Contains all gaskets and seals necessary for a professional-grade rebuild, ensuring zero flow issues and perfect factory-spec fitment.
This Suncoast 10R140 rebuild kit provides a vital upgrade to your 2023-2024 6.7 Powerstroke-equipped Ford F-250, F-350, F-450, or F-550. By combining the exceptional durability of Raybestos GPZ clutches and high-performance steels with the essential factory Thermal Flow Control Filter and high-quality gaskets, you are investing in the sustained power and efficiency that the advanced 10R140 transmission was designed to deliver. Don't simply replace worn parts; upgrade your transmission's internal components to handle the demands of your powerful truck, maintain its advanced shift recovery, and ensure superior, long-lasting performance.
