The T56 Manual Transmission is a 6-speed transmission which can adapt for many different types of applications. Originally, the T-56 Manual Transmission was designed and built by Borg-Warner for the Dodge Viper. In 1992, General Motors began using it for its generation II and future engines. As of 1998, Tremec took over building the T56, but left it as is without changing anything.

Features of the T-56 Manual Transmission

The Tremec T56 manual transmission is one of the most sought after features in cars that demand enhanced performance, high speed and additional strength. The technology used in cars with T56 transmission is what sets it apart from other transmissions.

T-56 Manual Transmission features:

  • Hydraulic clutch
  • Bell housing, brass synchros on some models
  • Stainless steel materials
  • Lightweight
  • Easy to repair
  • Spare parts are readily available

Aside from these great features, a T56 transmission is highly reliable and incredibly efficient. It does work best with high performance cars since it can better manage high horsepower, without suffering any technical glitches. The ability to handle a higher torque is why this transmission is rated one of the best six-speed performers in today’s market.

The outside elements can be particularly harsh on a car and its transmission. Daily wear and tear eats away at it, resulting in reduced efficiency and reliability. But that is not the case with the T56 transmission parts. The stainless steel materials and bell housing and brass synchros provide extra protection and sustained performance so your can enjoy your vehicle for many years, without having to fix it or find replacement transmission parts which ultimately cost you a lot of money.

Because of its light weight, the T56 transmission works well with cars with different torque levels. It improves the overall performance of the car, in terms of convenience and the way it rides. Another great thing about this transmission is that you can drive a lot more miles with a lot less fuel. This is a major bonus in a time when gas prices are at an all time high.

People who prefer automatic transmissions sometimes try to convince others that you do not get the same level of quality with a manual transmission. The T56 transmission defies that belief by offering a high level of dependability, long life and a fun factor no automatic trans can come close to. If you should eventually need T56 transmission parts, they are easy to get and easy to install. If a T56 transmission rebuild is required, they usually involve an upgrade steel three to four fork as well as rugged billet steel keyways, which replace the aluminum parts. Upgrading the carbon fiber synchros will help with regards to gear banging resistance.

Inside High Gear’s Tremec T56

Do you have an old hot-rod restoration project? Do you have a T56 that shifts rough? If so, then our custom Tremec T56 is essential for you! We were founded in 1989, so after 20+ years of experience, High Gear Transmission has perfected the T56 rebuild.

Most manual transmissions have 3 shift rails and this can cause problems, because there are more internal gears and parts which can break. The T56 was innovatively engineered with 1 shift rail, so there are fewer parts to tear up, and no jamming, while delivering faster, smoother shifts. The T56 will bolt to most any Chevy with a 5.7 liter motor, so it has been an extremely popular transmission since its birth into the automotive industry. Many folks consider the T56 the best 6-speed on the planet.

The T56 is an extremely reliable, well-built transmission, ask any T56 owner, but like any mechanical part it will eventually wear out and break down. Do not let some quack rebuild your beloved T56. Repairs, new transmissions, parts, and labor becomes increasingly tough on the wallet and quite stressful, but worry no more! The experienced trusted staff at High Gear is here for You! High Gear Transmission can sell you a quality T56 ‘reman’ and have you back on the road in no time.

High Gear completely dissembles the entire T56 unit and looks over every single internal part, down to the last spring. Any part that is worn, or may cause failure or problems in the future is replaced with tested proven parts. High Gear Micro-Polishes all the gears and parts for smooth and quit shifting. All parts are soaked in the hot tank with a special mineral solvent, then every part is blown dry with high pressure air; finally everything is laid out to be reassembled by the trusted experienced staff at High Gear.

The Tremec T56 ‘reman’ is full of specialized High Gear upgrades. High Gear replaces the plastic shifter bushing with a brass bushing which is stronger, more reliable, and will not wear out. The original aluminum 3/4 fork is upgraded to steel providing a much stronger fork which is less likely to break. The plastic fork pads are upgraded with thicker brass fork pads. The brass fork pads, have a longer lifetime, and will not harden or become brittle and break like the plastic fork pads. Debris build-up is extremely detrimental to the T56 and can easily break gears. High Gear uses two circular magnets to catch any metal shavings or debris that over time would build up in a unit, thus increasing the lifetime of a T56. Once High Gear has completed the internal ‘reman’ process, the T56 is reassembled with cases that have been bead blasted, steam cleaned, and powder coated, for optimal durability of exterior casing and looks like a piece a candy. It almost makes you want to eat it.


All High Gear ‘reman’ transmissions are rebuilt with new bearings and small parts kit, and the syncro rings are changed from paper to carbon fiber. After reassembly, all transmissions are tested on the High Gear professional dyno testing machine. The professional High Gear dyno provides the most accurate testing results to assure the unit does not leak, squeak, moan, groan, rust, bust, or collect dust. The dyno simulates an applied heavy load with a high rate of speed, thereby assuring the unit operates with the maximum performance under the toughest conditions.
