Yes boring but better safe than sorry. The pan temp gives us a good look at average core temps once the gears have been lubed. The fluid can be much hotter right out of the converter as it’s routed toward the cooling system but that would be reflected in a pan monitored system and not as much of a concern as the constant core temp.

Agreed, that is precisely why I chose to monitor my temps from that spot. The extra work to install the sensor there I think is well worth the effort.
Properly working and serviced A442F/A343F transmissions run remarkably cool....but as you say are best monitored if you do any towing or hard off-roading.
