Tremec Magnum-F 6-Speed Manual Transmission

The Grannas Racing GM Tremec Magnum-F is a high-performance 6-speed manual transmission engineered for GM vehicles, specifically noted as a bolt-in swap for 4th-generation Camaro and Firebird models (1998-2002). This transmission represents the pinnacle of strength and power rating for 6-speed units, capable of handling up to 700 lb-ft of torque. It features internal components constructed from 4616 chromoly, including gears and shafts with substantially increased face widths. The design incorporates a one-piece counter shaft and triple cone synchronizers, ensuring enhanced durability and precise shift control. The Magnum-F also boasts an isolator-type shifter, reducing cabin noise and vibration while providing a crisp, communicative shift feel. This particular configuration is the wide-ratio unit, offering gear ratios of 2.97, 2.10, 1.46, 1.00, 0.74, and 0.50. It is designed to be a direct replacement for T-56 transmissions, utilizing the "fbody" tailcase for seamless integration into applications that previously used Borg Warner or "LS T56" units. While primarily highlighted for 4th-gen F-bodies, its design also makes it compatible with other applications featuring similar shifter positions, including third-generation F-bodies, LT1-powered fourth-gens, LS-swapped late models, and sport compacts like A80 Supras and FD RX-7s. The transmission comes with a factory Tremec 1-year warranty. It is reasonably light at 135 lbs dry and is constructed from 100% brand-new, OEM-quality content.
