PPE 225065100 Transmission Fluid Thermal Bypass Valve
Protect your transmission from overheating with the PPE Transmission Fluid Thermal Bypass Valve. This billet aluminum upgrade replaces the restrictive factory thermal bypass valve, delivering unrestricted fluid flow to the cooler for better temperature control and long-term reliability.
The Problem with the OEM Valve
The factory thermal bypass valve on 2019–2024 Ram 2500 and 3500 trucks uses restrictive internal passages. When it fails (due to mechanical issues or debris), transmission fluid can be blocked from reaching the cooler. The result is elevated fluid temperatures that accelerate wear and increase the risk of transmission damage—especially under towing, heavy loads, or stop-and-go driving.
The PPE Solution
The PPE 225065100 eliminates the constrictive OEM valve entirely. It maximizes continuous fluid flow to the transmission cooler, improving cooling capacity and helping keep temperatures in a safer range whether you’re hauling or commuting.
Key Features
- Billet aluminum construction – Durable, precision-machined design built for long service life
- Unrestricted fluid flow – Removes factory restrictions for improved cooling efficiency
- Neodymium magnet service plug – High-strength magnet with O-ring seal captures ferrous debris and wear particles; removable for easy cleaning and inspection
- Direct-fit installation – Drop-in replacement with no modifications required
- Helps prevent overheating – Supports lower transmission temperatures under demanding conditions
Fitment
- 2019–2024 Ram 2500 / 3500 6.7L Cummins (68RFE and AS69RC/Aisin transmissions)
- Also fits 2019–2026 Ram 2500 / 3500 6.4L gas models
- Note: Not compatible with 2025–2026 Ram 6.7L Cummins diesel
Replaces OEM part: 68359848AD (and similar variants)
A simple, high-value upgrade that improves cooling performance and adds active debris protection. Ideal for anyone who tows, works their truck hard, or wants extra insurance against a known factory weak point.
