Product Description

2014-2020 Dodge Ram 8HP70, 8HP75 Transmission Cooler Thermostat Bypass

The 2014 and newer 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. This unit also has a warming unit that unnecessarily pre-warms the transmission fluid to engine operating temperature. This means that almost immediately your transmission will be running hot at over 200 degrees. 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 our ZeroStat Technology this upgrade has several install configurations to suit all climates and needs! The options are:

Option One: Install warmer blocking plate only. This will get rid of the immediate unneeded heating of the transmission fluid. This will cause the transmission to run about 20 degrees cooler all the time and not heat up so quickly.

Option Two: Remove thermostatic valve only. Remove the plastic endplug which is notorious for cracking and leaking. Install the new brass endplug and omit the factory thermostat. This option will cause the unit to heat up quickly but run at a slightly lower temperature.

Option Three (Most Common): Install the warmer blocking plate and brass endplug upgrade and remove the thermostat. This will eliminate the rapid heating from the warming unit and then by also removing the thermostat you can expect up to a 50-70 degree drop in operating temperature. You will also have a 87% increase in cooler low by using this option as the restrictive thermostat is now removed and the maximum amount of cooler flow is now flowing.

In addition to these results the RevMax bypass system also gives you these upgrades!

Our billet Cooler Thermostatic Bypass Upgrade gives you these major advantages.

  1. There is no longer a thermal controlled bypass valve which can fail and cause lack of cooler flow and complete transmission destruction.
  2. 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.

  3. 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!

The RevMax Transmission Cooler Thermostatic Bypass Upgrade is a direct bolt in replacement. No lines are cut, nothing is altered. Simply disconnect your old lines unbolt your warmer plate and install the new items!
