Mishimoto Mopar Pentastar / Hemi Thermal Bypass Valve UpgradeThe transmission in your Jeep Wrangler 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 drivability 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
The transmission in your Jeep Wrangler 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 drivability 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 full-flow thermostatic bypass valve for the 2012-2018 Jeep Wrangler. The Mishimoto thermal bypass valve kit includes an all-aluminum CNC-machined housing that replaces the stock unit. This full-flow valve allows fluid to pump through the cooler as soon as the vehicle is started, eliminating the potential failure point of the stock bypass and providing cooling benefits. The full-flow design is beneficial to vehicles operating in hot climates, extreme driving conditions, or towing heavy loads. As with all Mishimoto products, this Full-Flow Transmission Thermal Bypass Valve Kit includes our signature Lifetime Warranty.This Part Fits:

Softer than expected

Not as firm as I would like. Make sure you want a soft pillow if you choose this one. Seems high quality otherwise

Super comfortable and great neck support
Size: Queen (Mid Loft), Number of Items: 1
This pillow is super comfortable!
It has support for the neck, which is so important so that my neck doesn’t end up creasing and cutting off your air. Great for side, sleepers or people that need a little bit more support. The height is about 5 inches- it appears firm, but it conforms to your neck shape and supports it. Great value for the money! I own four of them and guests finds them comfortable also

Perfect Pillow
Size: Queen (Mid Loft), Number of Items: 1
This is the best pillow I’ve ever had! Supportive yet soft. Never goes flat. I’m a side sleeper and I have neck and shoulder pain and this pillow keeps my head and neck in alignment. I’m buying a set for our camper and our 2nd home so I can sleep comfortably wherever I go. Price point is spot on for the quality of pillow.
