The Borg-Warner T-56 is a six-speed manual transmission used in several high performance cars from GM. Other manufacturers have used it too (like Dodge, in the Viper).
GM cars available with the T-56:
- 1997-2007 Chevrolet Corvette
- 1993-2002 V8 Chevrolet Camaro
- 1993-2002 V8 Pontiac Firebird
- 2004-2006 Pontiac GTO
- 2004-2007 Cadillac CTS-V
Borg-Warner sold the T-56 design to Tremec. Tremec continues to build, support, and improve the T-56.
The TR6060 is based on the T-56 and is built to handle more torque. It is used in the 2008 Corvette Z06, 2007 Dodge Viper, and 2007 Shelby GT500.
