TREMEC 1352-000-251 Details

Introduced in the early 1980s, the TREMEC T-5 5-speed has evolved into one of the most compact, lightweight, and versatile manual transmissions ever produced. The 1352-000-251 T-5 continues this legacy as a reliable, smooth-shifting solution for Ford applications, including the iconic 5.0L Mustang, while also excelling in hot rods, street cars, and custom builds where space and weight are critical considerations.

Over decades of refinement, the T-5 has earned a reputation for excellent drivability and durability in moderate horsepower applications. Its compact design makes it ideal for tight transmission tunnels, while its light weight improves overall vehicle balance and responsiveness. The T-5 delivers smooth, easy shifting with low effort, making it a favorite among weekend cruisers, street rod builders, and kit car enthusiasts.

Designed to handle up to 300 lb-ft of torque, the T-5 offers dependable performance along with a deep overdrive gear that enhances fuel efficiency and reduces highway RPM. Whether you're restoring a classic Ford or building a custom project, the TREMEC T-5 provides an outstanding balance of performance, simplicity, and value.

Overall Assessment

Customers have a mixed reaction to our transmission. While some faced issues with fitting-parts, one successfully fitted it in their '37 Ford/ '63 Falcon Gasser, highlighting its lightweight, compact size & usability in confined spaces. They praised our product’s performance, stating it outperforms when paired with our 9 in 4 link setup. Main criticisms focused on the output bushing quality. Note: These aren't reflective of general product quality.

I but this transmission for my 63 falcon gasser, but when I purchased a 37 Ford and I wanted to upgrade the Drivetrain. I did the ford thing, a 5.0 engine and I knew that 5 speed would be perfect To fit in the small confined space on the 37. I did add the S10 tail housing ( moves the shifter closer to the fire wall) it's small and lightweight and I'm running a 4:11 in the 9 inch, man it hauls out of the hole ! Ps I'm running your 9 in 4 link setup, love it !
