TREMEC TUKT16901 T56 Magnum XL 6-Speed Transmission Ford 2.66 1st

The TREMEC TUKT16901 T56 Magnum XL 6-Speed Transmission is a premium aftermarket manual transmission engineered specifically for 2005 and newer Ford Mustang applications . Built on the legendary TR-6060 platform, the Magnum XL delivers outstanding strength, smooth shifting, and race-proven durability, making it an ideal upgrade for high-performance street cars, pro-touring builds, road racing vehicles, and drag racing applications. Designed with an extended-length (XL) tail housing, the TUKT16901 positions the shifter in the factory location, simplifying installation while providing a rigid direct-mount shifter for crisp, precise gear changes. Unlike factory semi-remote shifter designs, the Magnum XL significantly improves shift feel and accuracy under aggressive driving conditions while maintaining excellent noise and vibration isolation. Rated to handle up to 700 lb-ft of torque and engine speeds up to 7,800 RPM , the Magnum XL is built with high-strength gears, premium synchronizers, and a reinforced one-piece countershaft capable of supporting naturally aspirated, supercharged, turbocharged, and stroker engine combinations. Dual overdrive gears reduce engine RPM during highway cruising for improved fuel economy, quieter operation, and reduced engine wear. Whether you’re replacing a factory transmission or building a high-horsepower Mustang, the TREMEC Magnum XL delivers the performance, reliability, and driving experience expected from one of the industry’s most respected six-speed manual transmissions.
