TREMEC T-56
The T-56 six-speed overdrive transmission was
developed for adaptation to a wide range of vehicle
requirements. The TREMEC T-56 has been
used on the Dodge Viper, Chevy Corvette Z06, Ford SVT Mustang Cobra, Aston Martin DB7 Vantage and V12
Vanquish, and Holden Commodore and Monaro.
The T-56 is no longer in production, it has been
replaced by the TR6060 for the OEM. The T-56
Magnum is the aftermarket replacement with over
700ft/lbs of torque capacity.
