TREMEC® T-56 MAGNUM XL 6-Speed S197/S555 Mustang Double Overdrive Transmission
TUKT12021 with a 2.97 first gear and .80/.63 Overdrives
Featuring all the most important content from the original Magnum, the XL retains its brute strength and sophistication but eliminates its multiple shifter locations and dual speedo outputs
The Magnum XL is an extension of our revered Magnum 6-speed series. Featuring all the most important content from the original, the XL retains the Magnum brute strength and sophistication but adds an extended-length tail section designed to eliminate the clumsy semi-remote shifter found in many popular late-model applications.
Currently available only for 2005-up S197 & S555 Mustangs, the Magnum XL includes an SFI-approved steel bell-housing with enclosure plate, a swap-specific cross-member, and an OE-quality transmission mount. For strength purposes, the Magnum XL also requires a 26-spline clutch and one-piece driveshaft (sold separately). Some applications may require speedometer e-calibration via ECU tuning or through the use of a separate signal converter.
