Starting in 2014, GM started installing a Thermal Bypass Valve on the transmissions. It acts like a thermostat, staying closed until the temp reaches approx 190 degrees, then opening to allow fluid to flow through the cooler. Mine did the same thing. During the hot as hell SC summers, mine would run up to 210 degrees before opening (unloaded) and never go below 190. I added a 20K btu Tru Cool tranny cooler and modified the bypass valve. Now I can sit in stop & go traffic at 175 degrees, or run the interstate at 75 mph at 145 degrees. If you guys are interested, I can turn you onto the mod. I doesn't cost anything.

i Know this has been few years ago can you still let me know what you did to get your tranny to run cooler please? thnaks my name is teddy
