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

Perfect Color
This shirt is so soft and the color is as depicted. Great mock turtle. Size is as expected. Ordered a large- 5’9 165# It fits well maybe a bit long but I wanted it loose.

Too short
Size: Medium, Color: White
Fit was okay, but the length was too short. I am 5'5" and if I tuck the shirt into my shorts or pants and raise my arms above my head, the shirt will pull out from my waistline/belt.
