The kingpin of TREMEC's high performance line-up, the T-56 Magnum double-overdrive 6-speed transmission takes the very best from TREMEC's current technologies and pairs it with the most popular features of the TKO 5-speed. Able to withstand a massive 700 lb-ft. of torque while providing unbelievably crisp shifts, no other manual transmission on the planet offers as much combined strength, versatility, and general ease-of-use as the T-56 Magnum. Known in its original equipment form as the 'TR-6060', the Magnum is an aftermarket version of the same transmission found in many of today's most celebrated factory super cars - giving you refinement where you want it and strength where it counts. The Magnum T-56 has a beefy 26-spine input shaft, 31-spline output shaft, 4616 chromoly gears and shafts, a one-piece countershaft and triple cone synchros. The close ratio gears are perfect for high performance driving with a tall overdrive for fuel economy and low rpms on the freeway. To be such a heavy duty transmission it's relatively light at around 135 lbs. without fluids. It comes with a short throw, low-effort shifter with smooth, precise engagement. The shifter can be placed in multiple locations on the case, and accepts most Hurst® bolt-on shifter levers, all of which really helps with swaps. Additional versatility is offered by its ability to accommodate both mechanical and electrical speedometers. Gear ratios: First 2.66, Second 1.78, Third 1.30, Fourth 1.00, Fifth .80, Sixth .63 Reverse 2.90
