In Akron, Gearstar Performance Transmissions builds high-performance automatic transmissions tailored to an engine’s power, gearing and intended application. Owner Zack Farah came out of a high-volume transmission operation more than 25 years ago to focus on the custom performance work that off-the-shelf units could not provide. Each transmission is handled by one builder, and the company remains under its original owner while its employee-owned team serves automotive enthusiasts across the country.
