Description

Converting your Mopar small block from automatic to six-speed manual transforms the entire driving experience. The TREMEC T56 Magnum double-overdrive 6-speed transmission takes the very best from TREMEC's current OEM technologies - the same transmission found in factory muscle cars like the Dodge Challenger and Viper - and pairs it with the most popular features of the TKO 5-speed. This is not just about adding gears; it is about adding capability, efficiency, and that unmistakable connection between driver and machine that only a proper manual transmission delivers.

The heart of this package is the T56 Magnum, capable of withstanding a massive 700 lb-ft of torque while providing unbelievably crisp shifts. The Magnum gears are forged, with the plate containing the engagement teeth laser-beam welded to each gear. This enables much more precise shaping of the engagement teeth with better pitch and angle control. The one-piece countershaft is much stronger than previous two-piece designs, with thicker journals and widened gear faces eliminating the weak points of older T56 units. Split ring retainers replace traditional snap rings, offering greater thrust load capacities and tighter tolerances.

This package addresses the complete conversion from automatic to six-speed manual. The system includes transmission options (with multiple gear ratio choices), Mopar-specific bellhousing for proper engine mating, flywheel assembly, clutch components in 10.5-inch diameter with 26-spline configuration, complete hydraulic release system with master cylinder and slave options, shifter components including Hurst and custom lever options, speedometer interface, transmission mount, and all necessary hardware. Depending on your specific vehicle, tunnel modifications will be required - MDL offers sheet metal tunnel extensions and floor supports that attach to the OEM floor pan for a clean, professional installation.

Every component in this package has been selected based on proven performance and compatibility. Our guided package selection process walks you through each choice, ensuring you get exactly what your build requires. When you are uncertain about any selection, our concierge service provides expert guidance to match components to your project and budget.
