PPE Transmission Fluid Thermal Bypass Valve

2016–2025 Dodge Durango / Jeep Grand Cherokee with ZF 8-Speed Transmission

225065200

Overview:

The PPE Transmission Fluid Thermal Bypass Valve is a precision-engineered upgrade designed specifically for Dodge Durango and Jeep Grand Cherokee models from 2016 through 2025 equipped with the ZF 8-speed automatic transmission. This high-quality billet aluminum valve replaces the restrictive factory bypass valve, enhancing transmission fluid flow to the cooler and significantly improving cooling efficiency. By ensuring optimal fluid circulation, it protects your transmission from overheating, especially under demanding conditions such as towing or stop-and-go driving.

Owners seeking to extend the life of their transmission and maintain peak performance will benefit from this direct-fit, easy-to-install solution. The PPE valve addresses common OEM valve failures caused by mechanical issues or debris blockage, which can lead to dangerous transmission overheating and premature component wear.

Key Features:

Engineered to maximize transmission fluid flow and cooling capacity, the PPE Thermal Bypass Valve offers several 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, offering superior strength and heat dissipation compared to the factory plastic or stamped steel components. The precision-machined internal passages are optimized for unrestricted fluid flow, eliminating the bottlenecks found in the OEM valve. This robust design ensures long-lasting durability under harsh operating conditions.

Additionally, the integrated Neodymium magnet in the service plug is strategically positioned to attract and hold ferrous debris, preventing metal particles from circulating through the transmission system. This feature enhances transmission longevity by reducing wear on internal components.

Installation & Fitment:

Installation of the PPE Thermal Bypass Valve is straightforward and requires no special tools or modifications. It 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. The valve mounts in the same location as the OEM part, allowing for a quick upgrade that restores proper fluid flow and cooling efficiency.

Because it is designed to OEM specifications, the valve maintains factory fitment and function while providing enhanced performance and protection.
