Details & Inspection Notes

The TREMEC TUKT12021 T56 Magnum XL 6-Speed Transmission is a premium, race-proven manual transmission designed specifically for 2005+ Ford Mustang Modular V8 applications, including Coyote and Godzilla engine platforms. Based on the legendary TR-6060 architecture, the Magnum XL combines OEM refinement with aftermarket strength, making it the ideal choice for high-performance street cars, track builds, and pro-touring Mustangs.

Featuring a 2.97:1 first gear ratio, double overdrive (0.80/0.63), and an impressive 700 lb-ft torque capacity, the T56 Magnum XL delivers exceptional acceleration while maintaining low highway cruising RPM. The extended XL tail housing places the shifter in the factory location, eliminating the semi-remote shifter found in many late-model Mustangs and providing shorter, more precise gear changes.
