Designed to Fit Your Classic
600 lbs/ft of torque capacity
American Powertrain ProFit Tremec TKX manual transmissions and installation kits are designed to fit your classic muscle cars. The TKX has a more streamlined case than the normally used OE design T-56 and T-5 which provides clearance in most transmission tunnels. The rigid 3-piece aluminum housing capable of engines speeds of 8,000 rpm with shifts at 7,500 rpm.
TKX 5-Speed Manual Transmission Features and Benefits
• Designed, tested and built specifically for the aftermarket.
• 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.
• 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.
• Built-in reverse light switch and cruise control safety switch.
