The T-56 six speed manual transmission has been used in a wide range of vehicles from General Motors, Dodge, and Ford Motor Company.
The transmission was originally designed and built by BorgWarner for the Dodge Viper later being used by GM in 1992 for the generation II and later engines, but from 1998 was built by Tremec, though nothing changed internally.
The transmission uses a hydraulic clutch, except for the Cobra which was mechanical.
The entire case, including the bell housing, is made of aluminum.
The transmission also features internal stops which render stopbolts on the shifter mechanism unnecessary.
