TREMEC 1352-000-251 T-5 5-Speed Manual Transmission Ford

The TREMEC 1352-000-251 T-5 5-Speed Manual Transmission Ford is a compact, lightweight, and reliable manual transmission designed for 1983–1993 Ford Mustang 5.0L applications, as well as street rods, kit cars, hot rods, and custom Ford performance builds. As the latest evolution of the legendary Borg-Warner T-5, this aftermarket “World Class” transmission delivers smooth shifting, excellent drivability, and a compact design that fits where larger transmissions cannot. Its lightweight aluminum case and overdrive fifth gear make it an excellent choice for moderate horsepower street cars and weekend cruisers.

Rated for 300 lb-ft of torque, the 1352-000-251 features a 2.95:1 first gear and 0.63:1 overdrive, providing strong acceleration while significantly reducing highway engine RPM for improved fuel economy and quieter cruising. The transmission utilizes a 10-spline input shaft, 28-spline output shaft, mechanical clutch release, and both mechanical speedometer compatibility and a factory-style shifter position, making it a direct solution for many Fox Body Mustang restorations and classic Ford performance projects.
