Does anyone know if the coolant temp & transmission temp are true readings? Once up to temp, it doesn't seem like my gauges vary much. No matter if I am pulling 13.5k trailer up a mountain on a 95* day. My last truck 2016 2500 w/66rfe I put in a thermal bypass valve to keep my tranny temps from hitting 200*. It opened up the oil getting to the cooler & kept my transmission 25-30* cooler. This truck 2022 3500 w/68rfe stays around 166-170* ALL the time, whether towing or not. I find this hard to believe.
