Built to Handle Serious Towing Demands

If you're driving a 1990 to 1993 Dodge RAM 2500 or 3500 with the legendary 5.9L Cummins under the hood, chances are you're putting that truck to work. Whether you're pulling a trailer, hauling gear, or just want your transmission to hold up under pressure, the ATS Towing Valve Body is built to deliver. Specifically engineered for the A618 non-lockup transmission, this performance valve body is designed to handle the heat and stress that come with heavy-duty towing. ATS incorporates a progressive line rise, meaning the transmission responds more smoothly and consistently as throttle pressure increases. That results in firmer, more predictable shifts when you're under load, which helps protect the transmission and keeps your truck running at its best when it matters most.

Proven Engineering from a Trusted Name

This isn’t some generic off-the-shelf upgrade. ATS has been building diesel performance parts for nearly 20 years, and their valve bodies are a direct reflection of that experience. Every unit is precision-machined in-house and tested for performance and durability. What makes the Towing Edition stand out is how it improves drivability without sacrificing reliability. You get quicker shifts, reduced shift flare, and a more confident feel whether you’re cruising the highway or climbing a steep grade with a full load behind you. Installation is straightforward and doesn’t require custom tuning, making it a practical upgrade for any diesel owner looking to extend the life of their transmission while getting better performance on the road.
