PPE Transmission Fluid Thermal Bypass Valve Billet

2016–2025 Dodge Durango / Jeep Grand Cherokee 3.0L EcoDiesel, 5.7L Hemi, 6.4L SRT, 6.4L 392, 6.2L Hellcat

Part #: 225065200

Overview

The PPE Transmission Fluid Thermal Bypass Valve is a precision-engineered upgrade designed for Dodge Durango and Jeep Grand Cherokee models from 2016 through 2025 equipped with the ZF 8-speed automatic transmission. This billet aluminum valve replaces the restrictive factory thermal bypass valve, significantly improving transmission fluid flow to the cooler and enhancing overall cooling efficiency.

Ideal for owners who tow heavy loads, drive in stop-and-go traffic, or operate their vehicles in demanding conditions, this valve helps prevent transmission overheating and premature wear. By ensuring optimal fluid circulation, it extends transmission life and maintains peak performance under stress.

With a direct-fit design, the PPE valve is an easy-to-install solution that addresses common OEM valve failures caused by mechanical issues or debris blockage, providing reliable protection for your transmission investment.

Key Features

Engineered to maximize transmission fluid flow and cooling capacity, the PPE Thermal Bypass Valve offers the following advanced features:

• Replaces the restrictive OEM thermal bypass valve with a high-flow billet aluminum design
• Improves transmission fluid circulation to the cooler, reducing operating temperatures
• Prevents transmission overheating during heavy towing, off-road use, or urban driving
• Includes a removable service plug equipped with a powerful Neodymium magnet to trap ferrous debris
• Magnetic plug allows easy maintenance by capturing metal particles before they circulate through the transmission
• Direct bolt-on replacement with no modifications required
• Durable construction resists corrosion and withstands high operating temperatures
• OEM Part Number 68291739AA compatible for seamless integration

Construction & Design

The PPE Transmission Fluid Thermal Bypass Valve is crafted from premium billet aluminum, providing superior strength and enhanced heat dissipation compared to factory plastic or stamped steel components. Its precision-machined internal passages are optimized for unrestricted fluid flow, eliminating bottlenecks commonly found in the OEM valve.

This robust design ensures long-lasting durability under harsh operating conditions, while the integrated Neodymium magnet in the service plug captures ferrous debris to prevent metal particles from circulating through the transmission system. This feature reduces internal wear and contributes to extended transmission longevity.

Installation & Fitment

Installation is straightforward and requires no special tools or modifications. The PPE Thermal Bypass Valve is a direct replacement for the factory valve on 2016–2025 Dodge Durango and Jeep Grand Cherokee models equipped with the ZF 8-speed transmission. It mounts in the exact location as the OEM part, allowing for a quick and hassle-free upgrade that restores proper fluid flow and cooling efficiency.

Designed to OEM specifications, this valve maintains factory fitment and function while delivering enhanced performance and protection.
