(Borg-Warner T-56)

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 Borg-Warner, but as of 1998, is built by Tremec, though nothing changed internallyTemplate:Fact. The T-56 has been succeeded by the Tremec TR-6060 transmission in many former T-56 applications, as well as applications requiring greater strength than the T-56 could offer.

Features

The transmission uses a hydraulic clutch, except for the Cobra which is mechanical and had an 11 inch clutch disk. The entire case, including the bell housing, is made of aluminum. The T-56 has a synchromesh made up of brass synchros for the GM and Ford applications, and stainless steel in the Dodge application. The transmission also features internal stops which render stopbolts on the shifter mechanism unnecessary.
