Introducing the Chevrolet Silverado 2500HD Transmission Cooler Thermostat Bypass Plug by Wehrli. This billet anodized plug, available in a sleek black finish, is designed for the 2017-2019 Duramax models. It's an essential upgrade that directly replaces the OEM thermostat, enhancing your vehicle's transmission cooling efficiency.

Engineered for both stock and built transmissions, the Wehrli Thermostat Bypass Plug significantly reduces fluid flow restriction to the trans cooler, providing fluid temperature drops ranging from 15 to 50 degrees Fahrenheit. This is crucial for trucks performing heavy towing in warm climates, where maintaining optimal fluid temperatures is vital to prevent transmission damage. The bypass plug is a quick and easy installation solution compatible with a wide range of GM vehicles equipped with a factory-installed transmission cooler thermostat bypass, ensuring a broader application scope.
