Boost transmission cooling performance and reliability with the PPE Transmission Fluid Bypass Valve engineered for 2012–2018 Jeep Wrangler JK and RAM 1500 models. This billet aluminum valve replaces the restrictive factory unit to improve fluid flow to the transmission cooler and help safeguard your drivetrain under load.

Key Features

• Maximized Cooler Flow: Eliminates restrictive OEM passages to increase transmission fluid flow to the cooler and help lower operating temperatures.
• Billet Aluminum Construction: High-strength aluminum body built for durability and long service life.
• Magnetic Service Plug: Removable neodymium magnet captures ferrous debris to protect internal transmission components.
• Direct Replacement: Simple bolt-in design installs quickly with basic hand tools.
• Maintenance Friendly: Service plug allows quick inspection and cleaning during routine maintenance.

Why Upgrade?

The factory thermal bypass valve can restrict fluid delivery to the transmission cooler or fail in the closed position, leading to elevated temperatures—especially during towing or heavy driving conditions. Replacing it with this PPE valve increases cooler flow, reduces overheating risk, and helps extend transmission life.

Fitment

Designed for 2012–2018 Jeep Wrangler JK and RAM 1500 vehicles equipped with the compatible automatic transmission cooler line that uses this style of bypass valve. Always verify vehicle compatibility before ordering.
