Description

The kingpin of Tremec's high performance lineup, the T-56 Magnum double-overdrive 6-speed manual transmission, takes the very best from Tremec's current OEM technologies and pairs it with the most popular features of the TKO 5-speed. 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. Able to withstand a massive 700 lbs.-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. The units are available in a variety of gear ratios for different applications.

Additional details:

* The aftermarket's premier double overdrive 6-speed performance manual transmission
* Reasonably light at 135 lbs. dry
* Multiple shifter locations and dual speedo pickups for unmatched versatility
* Incredibly short, extremely low-effort shift throws, with crisp, precise engagement
* Modern OE supercar technology for the ultimate pro-tourers, road-racers, and more
