So while some may see a 240 reading, they may not know where that reading is derived from making their concern unwarranted.
Also note, Toyota Tundras and Sequoia's have a thermostat that keeps ATF around 200 at all times. Only recently did I find an app that will monitor highs and lows as the add in temp monitor I had in my Honda. And in all the towing I did in recently in day time temps reaching 121, the ATF temp gauge never budged. It appears automotive engineers might know what their doing.
