Mishimoto 2016-2020 Jeep Grand Cherokee Thermal Bypass Valve Kit

Mishimoto is known for making well-built cooling system upgrades, and this thermal bypass valve kit for your 2018-2024 Dodge Durango is no exception. Your transmission handles a lot of power, and that power creates heat. If that heat isn't managed, it can lead to serious transmission damage. The stock thermal bypass valve is supposed to control fluid flow to the transmission cooler, only letting fluid through once it reaches operating temperature. However, the thermostat inside these stock valves can fail, preventing fluid from ever reaching the cooler and causing your transmission to overheat.

This Mishimoto kit replaces that failure-prone stock valve with a CNC-machined billet aluminum unit that's built to last. It features a serviceable thermostat for quicker warm-up in colder climates. Plus, you can install a bypass to ensure constant cooling, which is great for warmer areas or if you do a lot of towing or aggressive driving. The internal passages are machined to improve fluid flow over the stock valve, making your transmission cooler work more effectively. Even the exterior of the valve has cooling fins machined into it to help dissipate extra heat.

This kit is designed to be a direct replacement for your stock valve, making installation straightforward. It comes with a durable black anodized finish and Mishimoto's lifetime warranty, so you can be confident in its longevity.
