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 equipped with the ZF 8-speed automatic transmission from 2016 through 2025. This billet aluminum valve replaces the restrictive OEM thermal bypass valve, enhancing transmission fluid flow to the cooler and significantly improving cooling efficiency. By ensuring consistent fluid circulation, it protects your transmission from overheating, especially under demanding conditions such as towing or stop-and-go driving.

Built for enthusiasts and daily drivers alike, this valve addresses a common failure point in the factory design. The OEM valve’s internal passages can become clogged or fail mechanically, cutting off fluid flow to the cooler and risking costly transmission damage. PPE’s solution maximizes fluid flow while adding a magnetic service plug to trap ferrous debris, extending transmission life and reliability.

Key Features:

The PPE Transmission Fluid Thermal Bypass Valve offers several critical advantages over the factory component:

• Replaces the restrictive OEM thermal bypass valve with a high-flow billet aluminum design
• Maximizes transmission fluid flow to the cooler for enhanced heat dissipation
• Prevents transmission overheating during heavy towing, off-road use, or urban driving
• Includes a removable Neodymium magnet-equipped service plug to capture metal debris
• Easy bolt-on installation with no modifications required
• Durable construction resists corrosion and mechanical failure
• Direct OEM part replacement (OEM Part # 68291739AA)
• Compatible with Dodge Durango and Jeep Grand Cherokee models from 2016 to 2025 with ZF 8-speed transmissions

Construction & Design:

Manufactured from premium billet aluminum, the PPE Thermal Bypass Valve offers superior strength and corrosion resistance compared to the stock plastic or stamped metal OEM valve. The internal flow passages are engineered to eliminate the restrictive bottlenecks found in the factory design, allowing unrestricted fluid movement to the transmission cooler. The valve’s precision machining ensures a perfect fit and reliable operation under all driving conditions.

Additionally, the integrated Neodymium magnet in the service plug is strategically positioned to attract and hold ferrous particles circulating in the transmission fluid. This feature helps prevent premature wear of transmission components by removing harmful debris from the system during routine maintenance.

Installation & Fitment:

Installation of the PPE Transmission Fluid Thermal Bypass Valve is straightforward and requires no special tools or modifications. It is a direct OEM replacement designed to fit perfectly on 2016–2025 Dodge Durango and Jeep Grand Cherokee models equipped with the ZF 8-speed automatic transmission. The valve mounts in the same location as the factory unit, allowing for a quick upgrade that can be completed in under an hour by a professional or experienced DIYer.

Because it improves fluid flow and cooling without altering transmission operation, no additional tuning or adjustments are necessary after installation.
