Product Description

Tremec 5-Speed TKO 500 Transmission with a 10-Spline Input Shaft.

Tremec has been providing the gearheads of the world with slick-shifting gearboxes since 1964, and in the process they have become one of the most respected players in the transmission industry. While Tremec manufactures many of the OEM transmissions that modern cars come equipped with, they also supply the tuner market with a number of excellent options to upgrade cars that require more power handling capacity. The TKO 500 is one such example, and will fit many popular Mustangs.

Those with later model cars will be most interested in the TKO 500 for its higher torque capacity compared to their factory Mustang transmission, which is perfect for applications where engine output has been raised with the addition of aftermarket parts like a supercharger or nitrous kit from CJ Pony Parts. Installing this new transmission will give you the confidence to launch and shift your car without the danger of damaging internals.

Performance and Speed

For those with older model, three and four-speed cars, the addition of a fifth (and, for some, a fourth) gear really opens up the tractability of your car, and can lead to huge improvements in acceleration. While the Mustang isn’t known for offering weak engine options, the tall ratios required to achieve highway speeds using a limited number of gears can keep your engine bogged down and out of the power band. Adding a gear or two with the TKO 500 allows for more evenly spaced ratios, and that means your lower gears can be tuned for acceleration while upper gears can deliver the fuel-efficient highway performance you desire.

To learn more about how the Tremec TKO 500 works, check out some of the highlights and technical specifications below:

- This transmission features a 500 lbs.-ft. torque capacity and a 10-spline input shaft
- Tapered roller bearings on input, output and counter shafts to improve performance (reduced noise factor)
- All gears and shafts made from special grade steel (ASTM 4615) that provides increased torque carrying capacity
- Equipped with a high-performance short-throw billet aluminum shifter that isolates road noise, while providing clean crisp shifts
- Neutral safety switch and back-up light sensor included
- Comes with dual electronic and mechanical speedometer pick-ups to suit all years

Equip your tuned Mustang with a Tremec TKO 500 from CJ Pony Parts and you’ll realize an instant improvement in shift quality and, very likely, acceleration. Tremec transmissions are built with performance in mind, so you can feel good about driving your car hard and knowing your transmission will stand up, shift after shift, with the same accuracy and direct feel it had the day you installed it. Plus, if anything ever does go wrong, you’ve got the backing of a world-class transmission manufacturer with decades of racing experience to support you.
