TREMEC® T-56 MAGNUM XL (Extended Length shifter) 6-Speed Double Overdrive Transmission ONLY TUET11940

TUET11940 – Magnum XL transmission is sold without the “Kit” for those that need a replacement transmission or wish to install a Magnum XL into many other platforms like a GM CTS-V or Gen 5 Camaro with a semi-remote shifter.
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

The Magnum XL  adds an extended-length tail section designed to eliminate the clumsy semi-remote shifter found in many popular late-model applications.
