The TREMEC TCET17765 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 engineering approach, the TKX combines universal fitment, excellent shift performance, and extreme durability to meet the demands of modern performance engines.
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 0.68 overdrive ratio improves highway drivability by reducing engine RPM, heat, and wear, while maintaining strong acceleration through close lower gearing. Combined with a compact, end-loaded design and multiple shifter locations, the TKX installs easily in a wide range of classic and custom Ford applications with minimal or no tunnel modification.
Built for strength and reliability, the TKX utilizes a rigid 3-piece aluminum housing, oversized gears, and premium materials throughout. Caged needle bearings and ASTM 4615 alloy steel components ensure long-term durability and increased torque capacity up to 600 lb-ft.
