ATS Billet Transmissions from ATS Diesel Performance have set the industry standard for performance built transmissions for nearly 30 years. Whether you’ve built your truck for work or play, a Billet Transmission from ATS will ensure years of reliability and confidence in your truck. Every transmission that ATS builds is dyno tested under load behind a diesel engine to allow the transmission to see full pressure at full lock-up torque before being shipped, and every transmission we build has an available 5-year, 500,000 mile warranty.
