Ford's 10R80 10-speed automatic is a strong transmission from the factory, but the stock torque converter is engineered for daily driving, not for holding down big horsepower. The Circle D Ford Pro Series 10R80 Torque Converter is purpose built for high horsepower 2018+ Mustang GT and F-150 applications, giving you a converter that can handle serious power while still being livable on the street.
Built to handle massive power. The Pro Series converter uses a modular clutch pack assembly with a holding capacity rated for over 2,000 lb-ft of torque, along with a billet steel front cover for added strength where it matters most. Clutch pack isolators help smooth out engagement and reduce harshness, so the converter can take serious abuse without beating up the rest of your drivetrain. This is the converter Circle D built for the guys running twin turbos, superchargers, or big power adders who need a transmission that keeps up.
Engineered with real fluid dynamics, not guesswork. Circle D uses CFD (Computational Fluid Dynamics) modeling to design a 5-axis billet steel stator combination that optimizes fluid flow through the converter for better torque multiplication and more efficient power transfer. The stator is furnace brazed and hand TIG welded, which holds up far better under load than the stamped and glued construction found in factory converters. A CDS exclusive deep groove ball bearing is used for smoother, more consistent operation, and Circle D's patent-pending flow control piston design helps manage lockup behavior across a wide range of power levels.
Dialed in for your specific setup. Every vehicle and power combination behaves differently, which is why Circle D offers configuration options to match your engine, power adder, and driving style. Whether you're running naturally aspirated, boosted, or nitrous, this converter can be tailored to deliver the stall speed and clutch engagement characteristics that fit your build, without sacrificing the ability to drive it on the street. Circle D recommends pairing this converter with valve body modifications, such as a Ratio-Tek RT-10R80-PRX, to get the most out of the upgrade.
