PPE Transmission Fluid Thermal Bypass Valve

2019–2024 Ram 2500 / 3500 6.4L / 6.7L Cummins Diesel

225065100

Overview:

The PPE Transmission Fluid Thermal Bypass Valve is a critical upgrade designed specifically for Ram 2500 and 3500 trucks equipped with 6.4L and 6.7L Cummins diesel engines from model years 2019 through 2024. This billet aluminum valve replaces the restrictive factory thermal bypass valve, enhancing transmission fluid flow to the cooler and significantly improving cooling capacity. Ideal for owners who demand reliable transmission performance under heavy towing, hauling, or stop-and-go driving conditions, this valve helps prevent dangerous overheating and extends the life of transmission components.

Unlike the OEM valve, which can fail in the closed position due to mechanical issues or debris, the PPE valve ensures consistent fluid circulation to the transmission cooler. This upgrade provides an extra layer of protection for your transmission by maximizing cooling efficiency and reducing the risk of premature wear or failure.

Key Features:

The PPE Transmission Fluid Thermal Bypass Valve offers several advanced features engineered to improve transmission cooling and durability:

• Precision-machined billet aluminum construction for superior strength and durability
• Eliminates restrictive internal passages found in the OEM valve to maximize fluid flow
• Prevents transmission fluid starvation to the cooler, reducing overheating risks
• 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 designed for a perfect fit with no modifications required
• Enhances transmission cooling capacity, especially beneficial during towing and heavy-duty use
• Improves transmission reliability and extends component lifespan under demanding conditions

Construction & Design:

Crafted from high-quality billet aluminum, the PPE Thermal Bypass Valve is engineered for long-lasting performance and resistance to corrosion and wear. The valve’s internal design removes the restrictive passages present in the factory unit, allowing transmission fluid to flow more freely to the cooler. This design improvement ensures that the transmission fluid maintains optimal temperatures, even under strenuous operating conditions.

The inclusion of a Neodymium magnet in the service plug is a thoughtful engineering enhancement. This magnet captures ferrous debris circulating in the transmission fluid, preventing potential damage to internal transmission components. The plug is easily removable, allowing for quick inspection and cleaning during routine maintenance.

Installation & Fitment:

The PPE Transmission Fluid Thermal Bypass Valve is a direct replacement for the factory valve on 2019–2024 Ram 2500 and 3500 trucks equipped with 6.4L and 6.7L Cummins diesel engines. Installation is straightforward and requires no special tools or modifications. Simply remove the OEM valve and install the PPE unit in its place to immediately benefit from improved transmission fluid flow and cooling.

This upgrade is ideal for owners who frequently tow heavy loads, drive in stop-and-go traffic, or operate their trucks in demanding environments where transmission overheating is a concern.

What's Included:

• Billet aluminum PPE Transmission Fluid Thermal Bypass Valve
• Neodymium magnet-equipped removable service plug
• Installation instructions

Ideal For:

This valve is perfect for Ram 2500 and 3500 owners who want to enhance transmission cooling and reliability, especially those who:

• Tow heavy trailers or haul substantial payloads regularly
• Drive in urban environments with frequent stops and starts
• Operate their trucks in hot climates or challenging conditions
• Seek to extend the lifespan of their transmission components
• Prefer a durable, maintenance-friendly upgrade over the restrictive OEM valve

Pacific Performance Engineering (PPE) develops heavy-duty and performance upgrades for trucks and diesel platforms, including differential covers, transmission pans, oiling and cooling components, and other durability-minded parts. PPE products are built to handle heat, load, and power—ideal for tow rigs and performance builds that need stronger hardware and better fluid control.
