TKO 5-Speed Transmissions
TKO 500: Rated for a continuous 550 HP and 500 ft/lbs of torque, this gearbox has a low 3.27 1st gear and .68 5th gear. This is the most popular choice for the 1981-1993 XJS HE which has a 2.88 rear-end ratio. The low first gear gives dramatically better acceleration without changing the differential ratio. 5th gear is excellent for low-rpm cruising above 70 mph. Top speed is increased.
TKO 600: This gearbox will handle more than 700 HP and has a 2.87 1st gear and a choice of a .64 or .82 5th gear. These ratios are best suited to cars equipped with a 3.54 differential. The .64 5th gear is excellent for efficient high-speed cruising, whereas the optional .82 5th gear is excellent for road racing or other applications where you do not want a large rpm drop between 4th and 5th gears. Top speed is increased.
