TREMEC Magnum-F T56 6-Speed Manual Transmission

The TREMEC Magnum-F is the next evolution of the legendary T56 platform, built specifically for 1998-2002 GM F-body applications while offering dramatically improved strength, shift quality, and long-term reliability over aging factory units. Based on the proven TR-6060 / Magnum architecture, the Magnum-F delivers modern OEM-level durability with the precise shifting feel performance enthusiasts expect from TREMEC.

Designed as the perfect solution for LS1-powered Camaros and Firebirds, the Magnum-F also works well in a variety of swap applications including 3rd-gen F-bodies, LT1-powered 4th-gens, LS swaps, Supras, RX-7s, and other custom performance builds that require a shifter position between the standard Magnum and Magnum XL.
