Thermostat for Transmission Cooler for 3/8 inch Lines

If you’re running an aftermarket transmission cooler, dialing in your temps is just as important as upgrading the cooler itself. That’s where the ATS 310-901-3000 Auxiliary Transmission Cooler Thermostat comes in. Designed to keep your transmission operating right in the sweet spot, this kit offers a clean and effective way to manage cooling automatically—without the need for constant monitoring or guesswork. This thermostat setup is built to work with 3/8-inch cooler lines and includes a 180-degree thermal switch, giving you the ability to wire in your cooler’s fan so it kicks on exactly when it’s needed. Whether you're towing heavy loads, daily driving, or pushing your rig through tough trails, this kind of control ensures your transmission fluid stays at optimal temperature—reducing wear, preventing heat-related breakdowns, and ultimately extending transmission life. It’s especially helpful for setups with fan-assisted coolers, and the reversible fan compatibility gives you more flexibility during install.
