The TREMEC TKX 5-speed manual transmission is purpose-built for the aftermarket, delivering a compact, high-performance solution for Ford builds, restorations, and custom applications. Designed with a forward-thinking approach, the TKX combines universal packaging, exceptional shift performance, and extreme durability to meet the demands of modern performance engines and classic vehicle platforms alike.
Engineered for smooth, high-RPM operation, the TKX features advanced multi-cone synchronizers and hybrid carbon/bronze synchro rings, allowing for precise, consistent shifts at speeds up to 7,500 RPM. Its optimized gear layout reduces stress while minimizing noise, vibration, and harshness (NVH), making it ideal for both street use and performance driving.
The rugged 3-piece aluminum housing provides excellent structural rigidity, while oversized gears, premium materials, and caged needle bearings ensure long-term durability and increased torque capacity. Whether you're upgrading a classic muscle car or building a custom street machine, the TKX offers an ideal balance of strength, drivability, and modern refinement.
