Know that 'power mode' has several levels and each has engine/tranny temps as the basis to either turn on power mode, or drop down into a lower power mode


Right down to the various limp modes


All of those decisions are made based on engine/tranny temps


Not sure who you’re talking to. Are you referring to the tow mode feature?

Also my transmission gets up to 180 all the time now that I’ve installed the bypass thermostat. Before I installed it, I’d be lucky to get up to 130, pulling the trailer. No trailer, maybe 105. As far as a minimum, I was always of the train of thought, it needs to get warm enough to work out the moisture.
