PPE Transmission Fluid Thermal Bypass Valve

2019–2025 Ram 2500 / 3500 6.4L 392 & 6.7L Cummins Diesel

Part #: 225065100

Overview

The PPE Transmission Fluid Thermal Bypass Valve is a precision-engineered upgrade designed specifically for Ram 2500 and 3500 trucks equipped with 6.4L 392 HEMI and 6.7L Cummins diesel engines from 2019 through 2025. This billet aluminum valve replaces the factory thermal bypass valve, which is known to restrict transmission fluid flow and potentially fail under demanding conditions. By enhancing fluid circulation to the transmission cooler, the PPE valve significantly improves cooling efficiency, helping to prevent overheating and extend the life of your transmission components.

Ideal for truck owners who regularly tow heavy loads, haul substantial payloads, or drive in stop-and-go traffic, this valve ensures reliable transmission performance even under the most strenuous operating conditions. It offers a durable, maintenance-friendly solution that safeguards your investment by reducing the risk of premature transmission wear or failure.

Key Features

Engineered to maximize transmission cooling and durability, the PPE Thermal Bypass Valve includes several advanced features:

• Precision-machined billet aluminum construction for superior strength and corrosion resistance
• Eliminates restrictive internal passages found in the OEM valve to maximize fluid flow to the cooler
• Prevents transmission fluid starvation, reducing the risk of overheating and component damage
• Includes a removable service plug equipped with a powerful Neodymium magnet to trap ferrous debris
• Magnetic plug enables easy maintenance by capturing metal particles before they circulate through the transmission
• Direct bolt-on replacement with no modifications required for a perfect fit
• Enhances transmission cooling capacity, especially beneficial during heavy towing and demanding use
• Improves transmission reliability and extends component lifespan under harsh conditions

Construction & Design

Crafted from high-quality billet aluminum, the PPE Thermal Bypass Valve offers exceptional durability and resistance to corrosion and wear. Its internal design removes the restrictive passages present in the factory valve, allowing transmission fluid to flow more freely and maintain optimal temperatures. This is critical for preventing overheating during heavy-duty operation.

The valve features a removable service plug with an integrated Neodymium magnet, a thoughtful engineering enhancement that captures ferrous debris circulating in the transmission fluid. This helps protect internal transmission components from damage caused by metal particles. The plug can be easily removed for inspection and cleaning during routine maintenance, promoting long-term transmission health.

Installation & Fitment

The PPE Transmission Fluid Thermal Bypass Valve is a direct replacement for the factory valve on 2019–2025 Ram 2500 and 3500 trucks equipped with 6.4L 392 HEMI 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 enhanced cooling performance.

This upgrade is especially recommended for owners who frequently tow heavy trailers, operate in stop-and-go traffic, or drive in hot or challenging environments where transmission overheating is a concern.
