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

Finally found the right pillow for me. I have purchased quite a few latex pillows attempting to find the right one. I was apprehensive due to the support description being "extra soft". Yes, it's super soft when you pick it up and squeeze it, but it provides the perfect amount of support for side and back sleeping.

Absolutely awesome pillow! My sister and I used to have pillows like these as kids and always look to replace them. These are wonderful. Cool and comfortable and the perfect amount of firm and support . Spouses fight us for them!!

Nice foam latex pillow. A little thicker than I wanted, but has improved my sleep quality

Just what we were looking for.

Been buying these latex foam pillows for years. Definitely less firm due to it being “extra soft”. Soft and still somewhat supportive. Is not hot either. So glad I can still buy these pillows.
