About Gearstar Performance Transmissions

Building a Better Transmission Starts With Building a Better Company

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 "The high performance or racing transmission customer is building his pride and joy," explains Zack. "The demands placed on these machines is a lot different from those placed on the family car." Realizing that at that time very few companies were offering anything other than off-the-shelf transmissions from the big manufacturers, Zack split from Tristar and started Gearstar with the goal of building the best high performance transmissions specialized to the individual needs of the most discerning customers.

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.

To maintain consistency and quality during the building process, each transmission is handled by a single builder. We are also employee owned by people that have a true passion for what they do. Unlike many other transmission manufacturers that have been bought and sold three or four times over, Gearstar has only ever had one owner.

Zack sums up the attitude of Gearstar this way: "A transmission is what your wife has in her minivan. What we are building are horsepower transferring systems. Whether it is a Turbo 350 transmission going behind a mild small block or a 4L85E transmission built for a 528 Hemi, we approach each transmission as if is was going into our own personal car." It is that pride in craftsmanship that makes Gearstar the top choice for the most discerning drivers and enthusiasts.
