Introduced to the marketplace in 2012, the Magnum XL is a continuation of the popular Magnum 6-speed series. 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. Refinements include a new extended length tail section designed to eliminate the semi-remote shifter found in many popular late-model applications. Currently available for the 2005 and up S197 and S550 Mustang, the Magnum XL was designed specifically to replace the OEM 5 or 6 speed transmission where performance improvements are desired.
