TREMEC TKX 5-Speed Manual Transmission

For the development of the new transmission, TREMEC engineers took a forward-looking approach to finding the best and most efficient solution. This included universal packaging, excellent shifting performance, and extreme durability.

The end result is superior shift-ability with smooth shifts at high RPMs through the use of multi-cone synchronizers and hybrid synchronizer rings. At the same time, noise, vibration and harshness (NVH) performance is optimized with a gear layout to best control stress levels, while providing structural stiffness with a ribbed, 3-piece aluminum housing. Durability is further optimized with oversized gear widths, gaskets at all flanges and caged needle bearings in all gear positions.

Whether restoring or upgrading a classic muscle car or a 1930s-era roadster coupe, the new TREMEC TKX 5-speed RWD manual transmission delivers a top-quality drivetrain solution.

  • The TKX has 600 lb.-ft. of torque capacity and is capable of engines speeds of 8,000 RPMs with shifts at 7,500 RPMs.
  • Designed for multiple applications with three shifter locations. Compact, end-loaded design provides clearance in most transmission tunnels without floor modifications.
  • Increased case strength with three-piece aluminum housing provides outstanding structural stiffness (includes main case, intermediate plate and rear extension). Gaskets at all flanges simplifies installation and eliminates fluid leaks.
  • Superior shift-ability through use of multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon
  • Noise, vibration and harshness (NVH) minimized with gear layout to best control stress levels. All gears supported by caged needle bearings to reduce end play on the gears.
  • All gears and shafts made from special grade steel (ASTM 4615) providing increased torque carrying capacity.
  • Equipped with a high-performance short-throw billet aluminum shifter that isolates road noise, while providing clean, crisp shifts.
  • Robust design with internal three-rail shift system and steel shift forks.
  • Wide gear width increases gear life and torque capacity.
  • 26-spline input shaft with a 31-spline output shaft for added strength.
  • Built-in reverse light switch and cruise control safety switch.
