Mishimoto Thermal Bypass Valve Upgrade

2005–2020 Chrysler, Dodge, Jeep, Ram Models Various Engines

Part #: MMTC-JK-TBVFF

The Mishimoto Thermal Bypass Valve Upgrade is a precision-engineered direct-fit replacement designed to improve the transmission cooling system on a wide range of Chrysler, Dodge, Jeep, and Ram vehicles from 2005 to 2020. This upgrade replaces the factory thermostatic bypass valve, a common failure point that can cause transmission overheating or restricted fluid flow. By enabling full-flow transmission fluid circulation through the cooler immediately at startup, it ensures optimal temperature regulation for enhanced transmission durability and performance.

Ideal for drivers who frequently tow, operate in hot climates, or demand reliable transmission cooling under extreme conditions, this valve eliminates the risk of overheating caused by a stuck or malfunctioning stock valve. It provides consistent fluid flow without the flow restrictions inherent to the factory design, promoting longer transmission life and improved vehicle reliability.

Construction & Design

Crafted from high-quality aluminum, the Mishimoto Thermal Bypass Valve Upgrade features precision CNC machining to ensure a perfect fit and reliable operation. The all-metal construction not only enhances durability but also improves heat transfer away from the transmission fluid, aiding in effective temperature regulation. By removing the internal thermostat mechanism present in the stock valve, this design eliminates a common failure point and flow restriction. This robust engineering guarantees consistent fluid flow through the cooler regardless of ambient temperature, providing dependable transmission protection in all driving conditions.
