It's the take-no-prisoners gearbox that started a 5-speed retrofit revolution! TREMEC's TKO series of 5-speeds was first made famous by the 5-liter Mustang movement and has since been fitted into nearly every rear-wheel-drive performance application imaginable. Far and away the most versatile 5-speed on the market, the TKO offers an impressive array of flexibility features including multiple shifter locations, mounting configurations, gearing options, and speedometer pickups (electric & mechanical). Serving up 500 lb-ft. of tiremelting torque capacity along with confidence-inspiring shifts and fuel-saving overdrive, the TKO offers an ideal blend of brute strength and street manners which may be why it's the manual transmission behind more boulevard-bruising street machines and sportsman race victories than all of it's competitors combined.


  • The original 5-speed overdrive heavyweight
  • Up to 600 lb-ft. of torque capacity
  • Exceptionally light at just 99 lbs. dry
  • Multiple shifter locations & dual speedo pick-ups for extreme versatility
  • Robust 3-rail internal shift mechanism offers firm, positive shifts
  • Multiple gearing and overdrive options (see Technical Specifications)
  • TREMEC's most popular and widely used 5-speed; well-suited to a variety of builds
