Review on Enhanced Thermostatic Bypass Upgrade for 2013-2018 Dodge Ram 6.7L Cummins Diesel 68RFE Transmission Cooler by Revmax by Michael Walker

Works great but the price is a bit high for what I think it is. Plus, you can't go wrong with RevMax. The temperature of my 68rfe dropped by an average of about 30 degrees. One thing I have found is that since I added a 5" TBE my transfer rates are still slightly higher than normal as more exhaust gets closer to the transmission. In the near future I'll wrap the pipe around and see if it makes a difference.
