5-Speed Manual Transmission

The TREMEC TR-3650 is a robust 5-speed manual transmission engineered for performance vehicles with longitudinal engine configurations. This transmission is noted for its inclusion of a 5th gear that serves as an overdrive gear, enhancing fuel efficiency on the highway. It has been a key component in defining the driving experience for several generations of Ford Mustangs, starting from the 2001 model year. As a successor to transmissions like the T45, the TR-3650 incorporates modern upgrades and boasts an increased torque handling capacity. Sources indicate it can manage up to 575 ft-lb of torque and 725 horsepower, with potential for even more with modifications. This makes it a strong candidate for high-powered applications and a viable upgrade for those seeking enhanced performance. Applications for the TR-3650 are extensive, particularly within the Ford lineup. It is found in various models including the 2001 Ford Mustang Cobra, 2001 Ford Mustang Bullitt, 2001-2004 Ford Mustang GT, and the 2003-2004 Ford Mustang Mach 1. Beyond the Mustang, it has also been utilized in specific Australian Ford models such as the 2002 Ford Tickford Experience AU Series 3 TE50 and TS50, as well as the 2002 Ford AU Series 3 Falcon XR8 Pursuit 250. It is also manufactured for high-powered MG vehicles. For vehicles originally equipped with a T45 transmission, particularly GT and Cobra models with a mechanically driven speedometer, an aftermarket converter may be necessary when installing the TR-3650. The transmission is manufactured by Transmission Technologies Corporation.
