Sucks to have to drop the pan since I already did that only 5,000 miles ago when I did fluid and new filter service. That ATF is expensive!

Before you drop the oil pan and replace the heat sensor, plug in some kind of real time scan tool that can read the transmission temperature. If the sensor is on the fritz then it'll show some crazy number. My 540it had that issue in the winter, it would show the transmission temp as 130ºC after sitting all night! Now if the transmission temperature sensor is working and showing a correct number (as in, it starts cool when you start the car and rises as you drive) then that's not the issue. If the sensor starts showing a really high temperature when the car is at operating temperature, then you might have other issues like a bad transmission thermostat or a bad transmission heat exchanger. That's a very common issue with the early L322 Range Rovers (same M62tu and 5HP24).
