Diesel and drivetrain specialist

ATS Diesel Performance is an American brand focused on diesel vehicles, and especially on what sits between the engine and the wheels. When a diesel engine gets more power, the transmission and torque converter are often the weak link. That is why ATS has built its range around components designed to transfer the extra torque reliably, whether for towing, work or competition. The range is mainly aimed at pickups with the big American diesel engines from Cummins, Duramax and Power Stroke.

ATS Diesel’s key products

The core of the range is complete, reinforced automatic transmissions and torque converters built for more torque than the original parts. You’ll also find transmission parts such as valve bodies, clutch packs and transmission fluid cooling, so you can upgrade step by step. ATS also offers turbo systems and turbo upgrades, fuel system parts and various engine components. See each product for vehicle and engine fitment.

Frequently asked questions

Why upgrade the torque converter on a diesel?

A stock torque converter is designed for the engine’s standard output. When the engine makes more torque, it can start to slip or overheat. A reinforced torque converter transfers power more efficiently and copes better with towing and heavy loads.

Can I upgrade the transmission without replacing it?

Yes, often. Many start with parts such as a valve body, clutch pack or extra fluid cooling. If the vehicle runs very high power, a complete reinforced transmission may be the most durable solution.
