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

Prom approved
Size: Small, Color: Black
My son got this for prom.. follow the size chart given because it is accurate. It’s very dapper and for the price way cheaper than renting something. It doesn’t look cheap at all. Very classy

Don't trust AI it lies
Size: Large, Color: Red
The AI recommended the size based on my purchases and I tell you what AI was wrong because the pants didn't fit. Everything else did not.
