4. Revmax Transmission Cooler Thermostatic Bypass Upgrade Compatible
The 2019+ 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%.
This reduction in cooler flow causes the transmission to run hotter and also leads to transmission meltdowns. The completely re-engineered Billet 6061 Aluminum RevMax Cooler Thermostatic Bypass Upgrade module completely fixes all these complaints. Utilizing our ZeroStat Technology, We completely removed the orifice restriction for full cooler flow all the time.
This equates to lower operating temperatures and longer transmission life. Additionally, our billet Cooler Thermostatic Bypass Upgrade integrates aluminum cooling fins which aid in passive cooling of the block and fluid.
