Product Description

68RFE Transmission Cooler Thermostatic Bypass Upgrade

10 12 Bypass

**Located on drivers side by fuel filter and only on certain models during the ’10 – ‘12 years**

The 2010-2012 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%, 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 modules, completely fixes all of 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.

Our billet Cooler Thermostatic Bypass Upgrade completely eliminates the thermal bypass valve and this elimination gives you three major advantages.

  1. 87% increase in cooler flow due to the elimination of the orifice bottleneck located in the factory part.
  2. There is no longer a thermal controlled bypass valve which can fail and cause lack of cooler flow and complete transmission destruction.
  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; 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.
  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 our bypass upgrade you can use room temperature fluid to clean out your cooler anytime you wish without any special tools!

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 our new bypass.

    My transmission cooler thermostatic bypass valve failed which damaged my transmission. I had the transmission rebuilt with upgraded and heaver capacity clutch packs and parts. I had the original thermal bypass valve modified to stay in the open to cooler position. I decided to eliminate the original part and replace with the Revmax thermostatic bypass upgrade. The transmission ran 15 to 20 degrees F cooler with the Revmax upgrade. The shipping was fast and the bypass upgrade kit was a direct fit on the cooler lines. You will need a 13/16 open end wrench for the line fittings and a 1 inch wrench to hold the factory thermostatic bypass block when you loosen. You will then need a 7/8 wrench for the Revmax kit for holding the Revmax part while tightening. You only have to snug the lines as they are aluminum, do not He-man when tightening. The lines and the Revmax kit formed a great seal with no leakage. There is a small amount of transmission fluid loss when you disconnect the lines, so have a small container to catch it at the ready. If you have a 2010-2012 Ram 68RFE, I highly recommend this kit.
