The Tremec TXK is an all-new 5-Speed RWD Manual Transmission designed specifically for the aftermarket. -Better Fitment- Tremec wanted to keep all the great features of the TKO but streamline the case. So, they transitioned from the old top-load design to an end-load design, similar to the bulletproof Magnum. This move made the new TKX significantly stronger and allows the case to be much smaller. It is a great fit for a multitude of applications where space is at a minimum with little to no floor pan modifications and offers 3 shifter locations for maximum flexibility. -Better Performance- Another great advantage of the new design resulted in superior shift-ability with smooth shifts at high RPMs (up to 7500) through the use of multi-cone synchronizers and hybrid synchronizer rings as well as a 600 (yes, six hundred) lb.-ft. rating in torque capacity. At the same time, noise, vibration, and harshness (NVH) performance are 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 made of ASTM 4615 steel, gaskets at all flanges to eliminate leaks, and caged needle bearings in all gear positions.

Features:

  • Special grade steel shafts and wide gears provide 600 lb.-ft. of torque capacity, 8,000 RPM engine speeds and 7,500 RPM shifts.
  • Three-piece aluminum housing provides outstanding structural stiffness and increased case strength.
  • Gaskets at all flanges to simplify installation and eliminate fluid leaks.
  • Superior shift-ability through the use of multi-cone synchronizers.
  • Gear layout and caged needle bearings reduce end play while minimizing noise, vibration and harshness (NVH).
  • Single 0.68 overdrive reduces engine wear and fuel consumption.
  • Three shifter locations and a compact design allow multiple applications with little to no floor pan modifications.
  • 26-spline input shaft with a 31-spline output shaft for added strength.
  • Built-in reverse light switch and cruise control safety switch provide safety and creature comfort for any application.
  • GM case pattern, input configuration and integrated GM transmission mount pattern.
  • Includes stub shifter bolted to rear most location (reversible) that will fit most Hurst® shift levers.
