Everyone has differing opinions on what might be the most impressive muscle car, and the media has even created lists of favorites over the years. A motorhead in Cleveland, Ohio, may love the light, simply styled ‘68 Ford Mustang Shelby GT500 with its 428 big-block under the hood, and another in Annapolis, Maryland, may be obsessed with their ‘70 Olds 442 with its 455 big-block V-8 that can hit 60mph in six seconds. Regardless of the make and model, Gearstar Performance Transmissions in Akron, Ohio, manufactures high-performance automatic transmissions that will handle engines from 100 horsepower to 1,000+ and custom converters for street rods and hotrods, classics and collectibles. This custom manufacturing company has gearheads covered with their Ford, Mopar, and GM performance transmissions, such as the Turbo 350 transmission, or TH350. Each one is assembled with only the best American-made performance parts and put through rigorous testing to ensure its perfect function before it ever leaves the facility. Past customers in Pittsburgh, Pennsylvania, and beyond can attest to the fact that they offer extensive knowledge and treat each custom manufactured transmission as if it were going into their own vehicle.
