I have a P3 gauge and an OBD2 reader running live data while I drive, my coolant thermostat opens above 174F while driving because it never drops below that but the lowest if seen my trans temp was 95F on 2F day in VA (granted I only drove for about 30 min) and these are the readings I’ve been getting for the past year I didn’t pull these numbers out of thin air, i didn’t trust the plastic pan so I simply looked up a metal version and bought it and installed it then proceeded to review it for a year and posting my findings that’s all, I also regularly drive from VA to NY and on a 50F day my trans temp hovers around 165F, so either the sensors in the car are lying or I bought some miracle trans pan
