Mishimoto Mopar Pentastar/Hemi Thermal Bypass Valve Upgrade

The transmission is a vital part of your Mopar vehicle's drivetrain, whether it's a Jeep Wrangler, Dodge Charger, or Chrysler 300. Maintaining optimal transmission fluid temperature is crucial for performance and longevity. Mishimoto offers a direct upgrade for the factory thermal bypass valve, addressing a common failure point that can lead to transmission overheating.

Enhanced Thermal Regulation for Mopar Vehicles

Factory thermal bypass valves are designed to prevent overcooling in cold environments by restricting fluid flow to the transmission cooler. However, these units are known to fail, often sticking in the closed position. This failure prevents necessary cooling, leading to excessive heat buildup and potential damage to the transmission, especially under load or in hot climates. Mishimoto's upgraded valve ensures proper fluid flow when it matters most.

Key Features and Benefits:

  • Direct replacement for the stock thermal bypass valve in Mopar Pentastar and Hemi applications.
  • Robust construction designed for enhanced durability and reliability.
  • Ensures proper transmission fluid circulation to the cooler when operating temperatures are reached.
  • Prevents overheating issues caused by faulty factory thermostats.
  • Helps maintain optimal transmission fluid temperatures for improved performance and extended transmission life.

Why Upgrade Your Mopar's Cooling System?

A failing thermal bypass valve can compromise your transmission's health, leading to premature wear and costly repairs. This Mishimoto upgrade provides a reliable solution, ensuring your transmission receives adequate cooling, particularly in demanding driving conditions such as towing, performance driving, or navigating hot weather. Protect your investment and enhance your vehicle's cooling system efficiency.

Ensure your Mopar Pentastar or Hemi vehicle's transmission performs optimally and reliably. Choose the Mishimoto Thermal Bypass Valve Upgrade, available at GGCRACING.
