Mishimoto 12-18 Jeep Wrangler JK Transmission Thermal Bypass Valve KitThe transmission in your 2012 2018 Jeep Wrangler JK is the heart of its drivetrain. Whether you're hauling groceries or hitting the trail, it's vital to keep it performing at its best, and keeping the transmission fluid cool is crucial to that goal. In an attempt to balance driveability and the health of your transmission, Jeep fitted a thermostatic bypass valve to the lines that feed the transmission cooler. This valve ensures fluid doesn't flow

After years of having lemon grass planted in my yard, growing nearly out of control and a pain to manage, I now have a product that is small, smells the same, is inconspicuous and is the perfect thing to have around for summer picnics, evening playtime, camping trips, hunting trips, and so much more. Well worth the money spent!
