Tremec TUET 18131 Tremec GM Magnum XL 6-Speed Transmission:

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’s 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.
