PPE Transmission Fluid Thermal Bypass Valve Billet

2012–2025 Dodge Charger / 2015–2022 Dodge Challenger / 2013–2023 Chrysler 300 / 2021–2025 Jeep Wrangler 6.4L 392

Part #: 225065300

Overview

The PPE Transmission Fluid Thermal Bypass Valve is a precision-engineered upgrade designed for Dodge Charger, Dodge Challenger, Chrysler 300, and Jeep Wrangler models equipped with the ZF 8-speed 8HP90 transmission. This billet aluminum valve replaces the OEM thermal bypass valve to enhance transmission fluid flow and cooling efficiency, reducing the risk of overheating under high-stress driving conditions.

Stock thermal bypass valves can fail in the closed position due to mechanical wear or debris buildup, restricting fluid flow to the transmission cooler. This failure can cause dangerous transmission overheating, especially during launches, towing, or stop-and-go traffic, which accelerates transmission wear and shortens component life. The PPE valve eliminates these risks by removing internal restrictions and maximizing fluid circulation to maintain optimal transmission temperatures.

Key Features

Engineered to deliver superior transmission protection and reliability, the PPE Thermal Bypass Valve offers the following benefits:

• Direct replacement for OEM part #52014762AA with improved fluid flow characteristics
• Billet aluminum construction for exceptional durability and corrosion resistance
• Eliminates restrictive internal passages found in factory valves to prevent fluid starvation
• Prevents transmission overheating by ensuring consistent fluid flow to the cooler
• Includes a removable service plug with a powerful Neodymium magnet to trap ferrous debris
• Magnetic plug facilitates easy maintenance by capturing metal particles before they circulate
• Designed for seamless integration with the ZF 8-speed 8HP90 transmission system
• Enhances transmission longevity under demanding driving and performance conditions

Construction & Design

The PPE Thermal Bypass Valve is precision-machined from high-grade billet aluminum, providing outstanding strength, heat resistance, and corrosion protection. Its robust design eliminates the fragile mechanical components and restrictive passages prone to failure in OEM valves. The internal flow paths are optimized to maximize transmission fluid circulation, ensuring consistent cooling performance.

Additionally, the integrated Neodymium magnet in the removable service plug is engineered to attract and hold microscopic ferrous debris. This feature helps prevent premature wear of transmission internals by capturing metal particles before they can circulate through the system.

Installation & Fitment

Installation is straightforward and designed as a direct bolt-on replacement for the factory thermal bypass valve on compatible vehicles. No modifications or special tools are required, making this upgrade accessible for both enthusiasts and professional technicians. The valve fits the following models equipped with the ZF 8-speed 8HP90 transmission:

• 2012–2014 Dodge Charger 3.6L V6
• 2014 Dodge Charger 5.7L Hemi
• 2015–2022 Dodge Challenger 5.7L Hemi
• 2015–2022 Dodge Charger 5.7L Hemi
