Tremec GM TKX-500 5-speed transmission. Ships via truck freight.

TKX 5-Speed Manual Transmission Features and Benefits

• The all-new 5-speed, single overdrive manual transmission
• Designed, tested and built specifically for the aftermarket.
• 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.
•      It is available in multiple gear ratio configurations.
• 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 the use of multi-cone synchronizers.
• 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.
• 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.
• Separate GM and Ford case patterns and input configurations.
• Integrated GM and Ford transmission mount patterns.
