Description

Your '96-'98 Mustang's factory T45 is holding you back. With an input torque rating of just 325 lb-ft and a fragile 10-spline input shaft, that five-speed becomes the weak link the moment you add any serious power to your 4.6L Modular. This complete T56 Magnum conversion package delivers a massive 700 lb-ft torque capacity - more than double the factory transmission - along with a robust 26-spline input shaft that eliminates the T45's Achilles' heel once and for all.

The TREMEC T56 Magnum represents the pinnacle of aftermarket 6-speed technology. Based heavily on the TR-6060 found in factory muscle cars like the Dodge Challenger and Viper, the Magnum features substantially increased gear face widths with two-piece laser-beam welded construction for precise tooth angles and alignment. A one-piece countershaft resists distortion far better than previous designs, while triple cone synchronizers on gears 1-4 and double cone synchronizers on 5-6 deliver smooth, high-rpm shifts every time. The upgraded isolator-type shifter reduces in-cabin noise and vibration while providing the crisp, communicative shift feel the Magnum is known for.

This conversion is engineered specifically for the SN95 platform, requiring little to no tunnel modifications while maintaining your factory shifter position for a stock appearance. The double overdrive ratios drop cruising RPMs dramatically, improving highway fuel economy and extending engine life on those long pulls. Multiple gear ratio options let you dial in the perfect setup for your combination, whether you're building a boulevard cruiser or a dedicated road racer.

Our guided package builder walks you through every component selection - transmission, bellhousing, clutch, crossmember, driveshaft, and all supporting hardware. Compatible with 1996-1998 Ford Mustang GT and Cobra 4.6L applications converting from the factory T45 five-speed.
