2013-2018 Cummins RevMax 68RFE / AS69 ZeroStat Transmission Cooler Thermostatic Bypass

68RFE / AS69 Transmission Cooler Thermostatic Bypass 2013 – 2018

The 2013 and newer 68rfe and As69 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%, yes you read that right, 87%! No other bypass offers full unrestricted flow like the RevMax version does!

The completely re-engineered, Billet 6061 Aluminum RevMax Cooler Thermostatic Bypass Upgrade module, completely fixes all these complaints. Utilizing ZeroStat Technology, RevMax completely removed the orifice restriction for full cooler flow all the time. This equates to lower operating temperatures and longer transmission life.

This Billet Cooler Thermostatic Bypass Upgrade completely eliminates the thermal bypass valve and provides these major advantages:

1. RevMax ZeroStat Patented Technology, US Patent #11,137,070. 87% increase in cooler flow due to the elimination of the orifice bottleneck located in the factory part.
2. Eliminates thermal controlled bypass valve which can fail and cause prevent flow of transmission fluid to the auxiliary cooler which can result in overheating conditions and ultimately transmission failure.
3. Instead of closing off cooler flow when the transmission is cold and making your transmission generate unneeded heat that is hard to shed later; this bypass allows your truck to immediately begin cooling your transmission immediately and not waiting for it to get hot.
4. 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 this bypass upgrade you can use room temperature fluid to clean out your cooler at anytime you wish without any special tools!
5. Integral aluminum cooling fins aid in passive cooling of the block and fluid.

The RevMax 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.
