TREMEC TCET17805 TKX 5-Speed Manual Transmission, GM Mount

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.
GM case pattern and input configuration, integrated GM transmission mount pattern
26-spline input shaft with a 31-spline output shaft for added strength.
Built-in reverse light switch and cruise control safety switch.
