01/01/2020 T56 GEARBOXES NO LONGER AVAILABLE – REFERENCE ONLY
The kingpin of TREMEC’s high performance line-up, the all-new T-56 Magnum takes the very
best from current OEM technologies and pairs it with the most popular features of the all-
business 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 O.E. 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 including the ZR1 Corvette and sinister ACR Viper.
A world-class transmission in every respect, it’s the best transmission on the market for those
who will accept nothing less.
Just what is it that makes the TREMEC T-56 Magnum better than its predecessors?
Beefiness. Gears, shafts, bearings, synchros, the case, and forks were all dimensionally
increased for better torque handling capacity.
