    TREMEC TUET16363 Details

    The long-awaited and highly-anticipated F-car-specific version of TREMEC's popular Magnum 6-speed has finally arrived! Designed to replace T-56 transmissions in 1998-2002 GM F-bodies, the Magnum-F leverages TREMEC's TR-6060/Magnum architecture in order to provide fourth-gen enthusiasts significantly improved performance and relief from a shrinking pool of quality T-56 replacement parts.

    Born by the release of the original T-56 Magnum (now known simply as "Magnum") back in 2009, the Magnum-F fills a longstanding void in the overall Magnum line with regard to shifter locations; addressing not only LS1-powered 1998-2002 F-bodies, but several other applications that utilize a similar shifter position. Beneficiaries include third-generation F-bodies, LT1-powered fourth-gens, LS-swapped late models of all varieties, and sport compact applications such as A80 Supras, FD RX-7s, and more! Where the original Magnum shifter locations may prove too far forward, and the extended length Magnum XL's too far back, the Magnum-F's in-between position often proves to be just right.

    Inside, the Magnum-F benefits from the same durable componentry found in many of today's hardest hitting OEM muscle & sports cars. Over the T-56, the Magnum-F boast increased face-width on all gears, a robust combination of double and triple cone synchronizers, enhanced webbing in the main case, provisions for a cooler circuit and more! TREMEC also took the opportunity to upgrade the shifter to an isolator type unit, like that found on its Magnum XL. The shifter reduces in-cabin noise and vibrations while at the same time providing the precise and communicative shift feel that all Magnums are known for. And like all TREMEC aftermarket transmissions, the Magnum-F is made from 100% brand-new OEM-quality content.
