A transmission rebuild includes the labor and parts necessary to completely disassemble and re-build the transmission; any damaged parts will be replaced so the transmission will begin to run like new. High Gear Transmission is one of the fastest growing standard shift transmission rebuilders in the United States and with over 3 decades of experience in manufacturing and rebuilds, we have helped tens of thousands of people with their transmission at a price that makes sense.

Our Different Types of Transmissions

We have a number of transmission available at High Gear Transmission.

AX-15 Jeep Wrangler 

This transmission was used in Jeeps with an AMC 242 4.0L Inline 6 engine, as well as the AMC 258 4.2L. It was replaced by the NV3550 in 1999.


The AX5 has applications with the 1984-2006 Jeep YJ, XJ, and TJ models and variants can be found in Toyota cars and light truck applications.

GMC transmission rebuilders NSG-370 

The NSG370 is a top-shifting, longitudinally-loaded transmission. The NSG-370 features six speeds with a direct drive fifth gear and an overdriven sixth gear. The NSG370 manual transmission is fully synchronized in all gears and has helically cut gears for all speeds.


The NV-3550 is a longitudinally-loaded, top-shifting transmission used in Jeeps and smaller GM trucks.


The New Venture 4500 (NV4500) is a heavy duty manual transmission designed for Dodge or Chevrolet Trucks. The NV-4500 manual transmission is a top loading five-speed transmission with a cast iron case, aluminum top cover and dual PTO ports. It features all helical gears, and is fully synchronized.


The NV5600 was originally standard behind the high output 5.9L Cummins engine. The early NV5600 version, which was produced from 1998 midway thru 2000 is known to have synchronizer problems and a weak input shaft. In 2001, the NV5600 received an upgraded clutch, input shaft, and improved synchro design. This was in response to many issues owners had regarding these components, especially while towing heavy loads. All of our NV5600 units are completely upgraded and are backed by a warranty depending on your needs.

This transmission has been used heavily by car manufacturers such as GM, Ford, AMC, and Chrysler (during the early 60s).


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.


The G-56 is available in a full-size pickup truck and the only manual transmission currently available for class-5 and class-4 trucks. The G 56 is most commonly used in Ram trucks and Mercedes-Benz trucks.
