Transmission Cooler Thermal Bypass Valve:
The 2013 and newer 68RFE equipped Ram trucks have always been known to run hotter than then their early predecessors. There also have been numerous melted down transmissions due to the bypass valve sticking in the cold closed position. Lastly, the thermal bypass has a large restriction in it which reduces cooler flow by 87%.
The completely re-engineered Thermostatic Bypass Upgrade module, completely fixes all these complaints. The orifice restriction has been removed for full cooler flow all the time. This equates to lower operating temperatures and longer transmission life.
There is no longer a thermal controlled bypass valve which can fail and cause lack of cooler flow and complete transmission destruction.
Instead of closing off cooler flow when the transmission is cold and making your transmission generate unneeded heat that is hard to shed later; our bypass allows your cooler to immediately begin cooling your transmission and not waiting for it to get hot, just to try to cool it later.
You cannot properly flush your cooler lines without the aid of a hot flush machine that can get hot enough to open the bypass valve up. With our bypass upgrade you can use room temperature fluid to clean out your cooler at anytime you wish without any special tools!
Integral aluminum cooling fins aid in passive cooling of the block and fluid
Upgraded Filter Screw:
This is a must due upgrade to any 68RFE whether it be a stock transmission or upgraded. This is just as important as keeping the fluid level correct because if the filter loosens and falls off, complete transmission failure will occur.
The stock screw is cheap plastic and cannot be properly tightened to insure that it doesn’t loosen up over time. If overtightened the plastic screw will break. We recommend replacing the factory plastic screw immediately when purchasing a new or used truck regardless of the mileage. The steel screw can be used again and again during each filter change.
