Improve transmission cooling and reliability with the PPE 68RFE Transmission Thermostat Bypass Valve Block. Designed to replace the restrictive factory thermal bypass valve, this billet aluminium upgrade provides unrestricted transmission fluid flow to the transmission cooler, helping reduce operating temperatures during towing, touring and demanding Australian conditions.
The PPE 68RFE Transmission Thermostat Bypass Valve Block replaces the factory thermal bypass valve found on 2019+ Ram 2500 and 3500 models.
The OEM valve contains restrictive internal passages and relies on a mechanical thermostat to control transmission fluid flow to the cooler. If the factory valve sticks or becomes restricted, coolant flow through the transmission cooler can be reduced, contributing to elevated transmission temperatures and accelerated transmission wear under heavy loads.
The PPE billet aluminium replacement removes these restrictions, providing continuous transmission fluid flow through the transmission cooler for improved cooling performance and greater thermal stability.
For additional protection, PPE incorporates a removable Neodymium magnetic service plug, designed to capture ferrous wear particles circulating through the transmission system.
Whether your Ram is used for towing, touring, heavy work or performance driving, this simple upgrade helps improve transmission cooling efficiency and long-term reliability.
Transmission heat is one of the leading causes of automatic transmission wear.
Replacing the factory thermal bypass valve helps:
Ideal for:
Always confirm transmission compatibility before ordering
At Garage76, we regularly recommend transmission cooling upgrades for customers who tow caravans, carry heavy loads or operate in high ambient temperatures.
The PPE Thermostat Bypass Valve Block is a simple yet effective reliability upgrade that improves transmission cooler flow while eliminating one of the more restrictive components in the factory cooling circuit. Combined with the PPE Deep Transmission Pan, it forms an excellent transmission reliability package for the 68RFE.
