If you’re a late model performance enthusiast, chances are you know about Tremec.
Along with Borg-Warner, Tremec has manufactured some of the most well known 5-speed and 6-speed transmissions ever to be used as factory equipment in modern Mustangs, Camaros, Vipers, and other performance vehicles. Tremec manual transmissions have since become solid retrofit choices for just about any rear-wheel drive car in the high performance world.
Since Tremec and Borg-Warner essentially merged in the 1990s, most of the most popular 5- and 6-speed transmissions are now under the Tremec umbrella. Tremec offers a variety of aftermarket and motorsports-focused transmissions through companies like American Powertrain. These transmissions are based on legendary originals like the T-5 and T-56, but include new and better features.
To help make your Tremec aftermarket options more clear, we’ve put together a quick guide to Tremec transmissions and Tremec shifters. We’ve included an American Powertrain cross-reference name, an overview of each transmission, a breakdown of the specs and fitment guide (courtesy of Tremec), and some popular Tremec shifter options.
Stick cars are making a comeback.
Tremec never left.
Here are your aftermarket options.
Tremec T-5 5-Speed Transmission
Originally a product of Borg-Warner, the Tremec T-5 was introduced in the early 1980s and is still an original equipment transmission in overseas markets. Capable of easily handling up to 300 ft.-lbs. of torque, the T-5 offers smooth shifting and a deep overdrive.

Tremec TKO 5-Speed Transmission
For higher-horsepower vehicles, step up to the latest iteration of the legendary Tremec TKO 5-speed. American Powertrain sells the TKO 500 to handle as much as 500 ft.-lbs. of torque; the TKO 600 can take on as much as 600 ft.-lbs. of tire-shredding torque. Tremec recommends the TKO line for high-powered street machines and sportsman racers because of its combination of brute strength and street manners.

Tremec Magnum 6-Speed Transmission
Known as the TR-6060 in its factory form, the Magnum 6 is the aftermarket descendant of the T-56, which originated in the 1992 Dodge Viper. The T-56 eventually ended up in cars like the Mustang Cobra R, Chevrolet Corvette, and Chevrolet Camaro to name a few.
The Tremec Magnum 6-speed takes the best of the T-56 and incorporates features like a bolstered one-piece countershaft, stronger input shaft, redesigned shift forks, and highly modified transmission case. The Magnum 6-speed is built to deliver short, crisp shifts and handle up to 700 ft-.lbs. of torque.

Tremec Magnum XL 6-Speed Transmission
The Tremec Magnum XL is based on the regular Magnum 6-speed, but adds an extended length tail section to eliminate the clumsy “semi-remote” shifter found in many popular late model applications. This shifter is currently only available for 2005-up S197 and S550 Mustangs and includes an SFI-approved bellhousing with enclosure plate, swap-specific crossmember, and an OE-quality transmission mount. Like the Magnum, the Magnum XL can handle up to 700 ft.-lbs. of torque.
