Per PPE:

Add another measure of protection and increase fluid flow to the transmission cooler, boosting cooling capacity with the easy-to-install billet aluminum PPE Transmission Fluid Thermal Bypass Valve for Ram Cummins diesel.

The OEM part has restrictive internal passages. When the OEM valve fails in the open position, transmission fluid does not reach your cooler—caused by mechanical failure or debris. This can lead to dangerous overheating and shortened transmission life. The PPE Bypass Valve eliminates the restrictive factory valve, maximizing fluid flow from the transmission cooler.

For added protection, a Neodymium magnet-equipped service plug traps ferrous debris and allows for easy cleaning—something the factory valve lacks.

1. 87% increase in cooler flow due to elimination of the orifice bottleneck in the factory part.
2. No thermal-controlled bypass valve to fail and block cooler flow.
3. Immediate cooling begins at startup—no waiting for the transmission to heat up.
4. Allows cooler flushing with room temperature fluid—no hot flush machine needed.

This PPE 68RFE Transmission Cooler Thermostatic Bypass Upgrade is a direct bolt-in replacement. No lines are cut, nothing is altered. Simply disconnect your old lines and install them into the new bypass.

Note: Located underneath the truck, on the passenger side, near where the transmission housing and engine block meet.
