I hear you, but I do what I have to to make sure the engine doesn't get overly hot. With the A/C on.Remember that when the engine coolant is hotter, the transmission temp also rises. That day I ran AC while on the Rubicon my trans temp went up to 175 before I turned the AC off. Not only are higher temps not good for transmission life, more heat is radiated up into the cabin floor. So your head might be cooler with the AC on but your feet probably won’t be.
