Designed and manufactured by Tremec, the TR-3650 is a 5-speed manual transmission that was first introduced in the 2001 Ford Mustang GT & Cobra’s. They were installed halfway through 2001 replacing the T-45. FoMoCo needed a stronger gearbox that could withstand additional torque output, so they turned to Tremec for a redesign.
Today, HMS rebuilds & customizes the Tremec TR-3650 and offers various options given the customer’s specific needs. The TR-3650 uses a 3pc 1-2 advanced synchronizer design, and carbon-lined synchro rings for 3-4-5 & reverse which are standard in every build. HMS has enabled the popular Tremec 3650 to be a legitimate option in a world so often dominated by Tremec’s other products like its five-speed heavy-duty transmissions, TKO-500 and TKO-600, and its six-speed transmissions, such as the T56, TR6060 & Magnum units.
Considering the vehicle’s weight, power, traction/tire size, and even driving style. A modified TR-3650 can fit a lot of different combinations, and is an affordable alternative to other Tremec Transmission units.
