The factory transmission thermal bypass valve on many 2012+ Mopar vehicles is a known failure point. Designed to act as a thermostat that restricts fluid flow to the external cooler until reaching operating temperature, these stock units frequently stick in the closed position, leading to transmission overheating and potential internal damage. The Mishimoto Thermal Bypass Valve Kit (MMTC-GMP-TBV) provides a rugged, reliable solution to safeguard your drivetrain.

CNC-machined from 6061 billet aluminum, this housing features an integrated heat sink design for superior thermal dissipation and a durable black anodized finish. This kit is uniquely versatile, including both a serviceable 160°F (71°C) thermostat for cold-climate warm-up and a full-flow bypass plug for maximum cooling in extreme driving conditions or hot climates. Installation is straightforward, utilizing factory cooler piping and mounting points for a direct-fit upgrade.
