Description
The TREMEC TCET17722 TKX Close Ratio 5-speed manual transmission is purpose-built for the aftermarket, delivering a compact and high-performance solution for GM builds, restorations, and custom applications. Designed with a forward-thinking engineering approach, the TKX combines universal fitment, exceptional shift performance, and extreme durability to meet the demands of modern performance engines.
Featuring close-ratio gearing, this TKX is optimized for improved acceleration, tighter gear spacing, and performance driving. Advanced multi-cone synchronizers and hybrid bronze/carbon synchro rings provide smooth, precise shifts at engine speeds up to 7,500 RPM, making it ideal for both aggressive street use and track-focused builds.
Engineered for strength and reliability, the TKX utilizes a rigid 3-piece aluminum housing with a ribbed design for added structural integrity. Optimized gear geometry reduces stress while minimizing noise, vibration, and harshness (NVH). Premium internals, including caged needle bearings and ASTM 4615 alloy steel gears and shafts, ensure long-term durability and consistent performance under load.
Whether upgrading a classic GM muscle car or building a custom street machine, the TKX provides a modern drivetrain solution with outstanding drivability, strength, and installation flexibility.
