Gearstar Performance Transmissions

Specialties

Gearstar Performance Transmissions manufactures world-​class, high-​performance automatic transmissions built to exact specifications. From start to finish, they are built by the industry’s top expert technicians. We are employee owned by people that have a true passion for what they do, using only the best US made performance parts available.

Each transmission is custom re-​manufactured, built to specs — That means we don’t have pre-​built transmissions sitting on our shelves. In order to maintain consistency and quality during the building process, each and every transmission is handled by a single builder from start to finish. And every single transmission is put through rigorous qualification and inspection process, along with the fact that each transmission and converter are extensively dyno-​tested as a package equivalent of 100 mph on the street where we check hydraulic pressures, temperatures, shift quality, converter stall and lock-​up. We make sure each all shift points are at the correct RPM before engaging into the next gear.

When you receive your transmission and converter package, you can be sure it is functioning perfectly, because we make sure it’s perfect before it leaves our shop. Whether it is a Turbo 350 going behind a mild small block or a 4L85E built for a C5R 440 blown LSX, the same expert technicians will be working on either package. At Gearstar Performance Transmissions, we approach each project as if it was going into one of our own personal vehicles.

History

Established in 2001.

Gearstar’s owner, Zack Farah, got his start over 25 years ago at Tristar International where they were manufacturing upwards of 100 transmissions each day and 300 converters. While bulk production was Tristar’s bread and butter, the portion of the work on high performance transmissions drew Zack’s interest. From the many builders at his previous company, Zack selected the best 11 builders. He then cut those 11 down to just the top five. With a team made of truly «the best of the best,» Gearstar became one of the first companies to manufacture high performance automatic transmissions to the specifications of the engines, horsepower and torque output, rear gear ratio and the application which it is to serve.
