Mishimoto 12-18 Jeep Wrangler JK Transmission Thermal Bypass Valve Kit

The 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 through the cooler before the transmission reaches operating temperature, preventing overcooling in cold environments. However, when the thermostat in this valve fails, it's almost a guarantee your transmission will overheat. Moreover, those who live in hot climates will likely never have to worry about overcooling, rendering the valve a useless flow restriction.That's why Mishimoto has developed a performance thermostatic bypass valve for the 2012-2018 Jeep Wrangler JK. Our performance thermostatic bypass valve features a fully-serviceable and removable thermostat. For those who live in hot climates, the thermostat can be replaced with the included bypass to allow full flow to the transmission cooler at all times. Speaking of flow, the Mishimoto performance thermostatic bypass provides increased flow over the stock valve to ensure your transmission cooler operates at peak efficiency, even with the thermostat installed. The included thermostat opens at the stock temperature of 160°F (71°C), but the valve can be customized to suit your needs with any available Mishimoto thermostat.The Mishimoto performance thermostatic bypass valve is a direct-fit and is made from durable aircraft-grade aluminum that's anodized to withstand even the harshest environments. Like all of our Jeep products, our performance thermostatic bypass valve is backed by our Mishimoto Lifetime Warranty.This Part Fits: Year Make Model Submodel 2005-2007,2011-2014 Chrysler 300 Base 2005-2014 Chrysler 300 C 2012-2014 Chrysler 300 C Luxury 2005-2010 Chrysler 300 C SRT8 2005-2012 Chrysler 300 Limited 2008-2009 Chrysler 300 LX 2010,2012-2014 Chrysler 300 S 2009 Chrysler 300 Signature Series 2012-2014 Chrysler 300 SRT8 2013 Chrysler 300 SRT8 Core 2005-2010 Chrysler 300 Touring 2009-2014 Dodge Challenger R/T 2012 Dodge Challenger R/T Classic 2014 Dodge Challenger Rallye Redline 2009-2011 Dodge Challenger SE 2008-2014 Dodge Challenger SRT8 2012-2014 Dodge Challenger SXT 2012 Dodge Challenger SXT Plus 2006-2007 Dodge Charger Base 2017-2018 Dodge Charger Daytona 2017-2018 Dodge Charger Daytona 392 2006 Dodge Charger Daytona R/T 2018-2019 Dodge Charger GT 2018 Dodge Charger GT Plus 2006-2019 Dodge Charger Pursuit 2006-2019 Dodge Charger R/T 2017-2018 Dodge Charger R/T 392 2015-2016 Dodge Charger R/T Road & Track 2015-2018 Dodge Charger R/T Scat Pack 2019 Dodge Charger Scat Pack 2006-2017 Dodge Charger SE 2015-2018 Dodge Charger SRT 392 2015-2019 Dodge Charger SRT Hellcat 2006-2010,2012-2014 Dodge Charger SRT8 2006-2010,2012-2019 Dodge Charger SXT 2012,2018 Dodge Charger SXT Plus 2018 Dodge Charger SXT Plus Leather 2011-2013 Dodge Durango Citadel 2011-2013 Dodge Durango Crew 2011 Dodge Durango Express 2011 Dodge Durango Heat 2011-2013 Dodge Durango R/T 2012-2013 Dodge Durango Special Service 2012-2013 Dodge Durango SXT 2005-2008 Dodge Magnum R/T 2005-2008 Dodge Magnum SE 2006-2008 Dodge Magnum SRT8 2005-2008 Dodge Magnum SXT 2005 Dodge Magnum SXT Special Edition 2010-2011 Dodge Nitro Detonator 2010-2011 Dodge Nitro Heat 2007-2009 Dodge Nitro R/T 2009-2011 Dodge Nitro SE 2010-2011 Dodge Nitro Shock 2007-2009 Dodge Nitro SLT 2007-2008,2010-2011 Dodge Nitro SXT 2009-2010 Jeep Commander Limited 2009 Jeep Commander Overland 2009-2010 Jeep Commander Sport 2007-2013 Jeep Grand Cherokee Laredo 2007-2013 Jeep Grand Cherokee Limited 2007-2009,2011-2013 Jeep Grand Cherokee Overland 2012 Jeep Grand Cherokee Overland Summit 2007-2010,2012-2013 Jeep Grand Cherokee SRT8 2012 Jeep Liberty Jet 2008,2011-2012 Jeep Liberty Limited 2011 Jeep Liberty Renegade 2008,2011-2012 Jeep Liberty Sport 2016 Jeep Wrangler 75th Anniversary 2012-2018 Jeep Wrangler Rubicon 2012-2017 Jeep Wrangler Sahara 2012-2018 Jeep Wrangler Sport 2016,2018 Jeep Wrangler Sport S 2016 Jeep Wrangler Unlimited 75th Anniversary 2018 Jeep Wrangler Unlimited Moab 2012-2018 Jeep Wrangler Unlimited Rubicon 2012-2018 Jeep Wrangler Unlimited Sahara 2012-2018 Jeep Wrangler Unlimited Sport 2016,2018 Jeep Wrangler Unlimited Sport S 2018 Jeep Wrangler JK Rubicon 2018 Jeep Wrangler JK Sahara 2018 Jeep Wrangler JK Sport 2018 Jeep Wrangler JK Sport S 2018 Jeep Wrangler JK Unlimited Rubicon 2018 Jeep Wrangler JK Unlimited Sahara 2018 Jeep Wrangler JK Unlimited Sport 2018 Jeep Wrangler JK Unlimited Sport S 2012-2020 Ram 1500 Big Horn 2012-2018 Ram 1500 Express 2013-2020 Ram 1500 HFE 2012-2020 Ram 1500 Laramie 2014-2015 Ram 1500 Laramie Limited 2012-2020 Ram 1500 Laramie Longhorn 2015-2020 Ram 1500 Limited 2014-2020 Ram 1500 Lone Star 2012-2016 Ram 1500 Outdoorsman 2013 Ram 1500 R/T 2015-2020 Ram 1500 Rebel 2012-2018 Ram 1500 SLT 2014-2018,2020 Ram 1500 Special Service 2012-2018 Ram 1500 Sport 2012 Ram 1500 ST 2012-2020 Ram 1500 Tradesman 2012 Ram 1500 Tradesman HD 2013 Ram 2500 Big Horn 2012-2013 Ram 2500 Laramie 2012-2013 Ram 2500 Laramie Longhorn 2013 Ram 2500 Lone Star 2012-2013 Ram 2500 Outdoorsman 2012-2013 Ram 2500 Power Wagon 2012-2013 Ram 2500 SLT 2012-2013 Ram 2500 ST 2013 Ram 2500 Tradesman
