SunCoast Performance was established in 1989 initially as a two-man operation in beautiful Fort Walton Beach, FL. SunCoast was started with a yearning to answer the demand for high-quality aftermarket torque converters, transmission assemblies, and parts. Since that time, SunCoast has identified, tested, and corrected numerous failure points within the realm of OEM transmissions and torque converters. SunCoast uses its extensive test data in real-world scenarios, along with the latest technology in design methods to help formulate solutions to correct these failures.
