Our Mission is to Get Your Truck Upgraded with the Best Transmission Available!

ATS Billet Transmissions have set the industry standard for performance built transmissions for over 25 years. Whether you’ve built your truck for work, play, or competition, an ATS Billet Transmission will ensure years of reliability and confidence in your truck. All ATS Diesel Performance transmissions are designed to handle extreme power and heavy loads, and are dyno tested under load to ensure reliable functionality and high performance. ATS has a long history of working directly with our customers to develop transmissions and components that work equally well for daily use as well as extreme applications. Our engineers have studied, analyzed, and scrutinized original equipment manufacturer (OEM) transmission problems caused by high mileage and component failure, looking for ways to maximize longevity and performance.

This aggressive approach helped us develop the strongest, most reliable transmissions available for your domestic diesel truck. ATS performance transmissions eliminate the factory weaknesses and design flaws, replacing them with engineering that works. We’re so confident of that, all ATS transmission packages are backed by the only 5-year, 500,000 mile warranty in the industry.

When you are looking for a transmission to replace your worn out one, there are plenty of options out there for you to choose from. But when you are looking for a transmission that is not going to leave you and your family stranded on the side of the road and want to have a trouble-free experience, then there is only one choice. With industry leading innovation, invention, and manufacturing techniques, ATS transmissions are built to outlast, out-perform, and overcome the competition.

Whether your truck is a high-powered competition machine, a high mileage truck that needs improved fuel economy, a work vehicle that has to be durable, a truck you need to rely on for towing or simply a daily driver, ATS has the technology and products to fit your needs.

Seamless Allison Conversion for your RAM 5.9L or 6.7L Cummins with Full Factory Functionality

ATS Diesel has engineered the first fully integrated Allison transmission swap for Cummins powered vehicles. Backed by our proprietary TRANSLator® technology and our exclusive, patent-pending Allison to Cummins Bellhousing, the ATS Diesel Allison Swap offers complete factory functionality from your late model Ram; from push button start to tow/haul mode, electronic range select and electronic transfer case functionality. Our revolutionary new TRANSLator can-bridge module allows the Allison TCM to communicate with the Ram ECM and offers a seamless integration of all factory options on the truck with a nearly plug-and-play installation. Our exclusive, patent-pending Allison to Cummins Bellhousing allows a perfect factory match between the Allison and the Cummins with no additional fabrication required. The all-new ATS Diesel Allison Conversion Kit includes all necessary hardware and software to install an Allison LCT1000 behind your Cummins.

Putting your Horsepower and Torque on the Ground

The TripleLok torque converter was the breakthrough converter that started the triple disk revolution. With its patented square tab clutch construction and high torque lockup capabilities, the TripleLok set the standard by which all other torque converters are measured. The revolutionary ATS Five Star Torque Converter uses innovative fluid assist technology to provide exceptional power and reliability. This fluid coupling transfers more engine power to the transmission through the torque converter. Simply put, the Five Star Torque Converter’s efficient design equates to higher fuel economy, better performance and unsurpassed reliability for your Power Stroke, Duramax, or Cummins diesel truck. ATS’s Five Star® or TripleLok® Torque Converters, with our patented square tab construction, ensures that there is no slipping, vibrating, or wearing that is typical with round tab construction. Both of our torque converters can handle over 1700 foot-pounds of torque with factory line pressure, which is three to five times more than the factory converter. Couple its stall speed deftness with its maximum torque multiplication and this revolutionary torque converter technology results in increased efficiency with less mechanical energy turned into heat. What this means for you is better economy, more efficiency and more power to the wheels. In fact, we're so confident in the ATS torque converter line, that we offer the best warranty on the market and this is at any power level! All Five Star and TripleLok converters come standard with a 5-year/500,000 mile warranty!
