The Aftermarket's Premier Transmission Magnum 6-speed manual transmission

The kingpin of TREMEC's high performance line-up, the Magnum double-overdrive 6-speed transmission takes the very best from TREMEC's current OEM 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 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 muscle cars. Multiple shifter locations, giving you refinement where you want it and strength where it counts. Can be combined with any GM engine; big block, small block, or LS when using the correct bell housing.

Clutch Fork Included: No Clutch Type: Hyd Input Shaft Diameter: 1.125" Input Shaft Spline Quantity: 26 Output Shaft Spline Quantity: 31 Pivot Ball Included: No Shifter Included : Yes Torque Capacity: 700 Yoke Included: No Yoke Style: Slip On Speedo Output: Mech/Elec 1st Gear Ratio: 2.66 2nd Gear Ratio: 1.78 3rd Gear Ratio: 1.30 4th Gear Ratio: 1.00 5th Gear Ratio: 0.80 6th Gear Ratio: 0.63 Reverse Gear Ratio: 2.90
