6-Speed Manual Transmission

The Grannas TUET11009 is a high-performance, close-ratio 6-speed manual transmission engineered for GM LS engine applications. It is built upon the foundation of the TREMEC TR-6060, a transmission known for its presence in factory supercars, offering a blend of strength and streetable versatility. This transmission features a robust construction with 4616 chromoly steel gears and shafts, and a one-piece counter shaft. It is rated to handle 700 lb-ft of torque, making it suitable for demanding builds. The gear ratios are closely spaced to keep the engine in its optimal powerband, with a double overdrive (0.80 and 0.63) that enhances highway cruising and fuel economy. Specific gear ratios include 1st: 2.66, 2nd: 1.78, 3rd: 1.30, 4th: 1.00, 5th: 0.80, and 6th: 0.63. The input shaft measures 1-1/8" x 26-spline, and the output shaft is 31-spline. Designed for a modern sports car feel, the TUET11009 offers short, low-effort shift throws and smooth, crisp engagement thanks to its triple-cone synchronizers. For enhanced adaptability, it includes dual speedometer pickups and multiple shifter positions. This transmission is ideal for a variety of performance applications, including Pro-Touring builds, street/strip use, road racing, GM LS swaps, muscle car restomods, and performance crate engine projects. The TREMEC Magnum TUET11009 comes with a 1-year warranty from TREMEC.
