Transmission Fluid Temperature

The temperatures were measured off the OBD2 with a scan gauge. Not sure how accurate these OEM sensors are, but it sure beats looking at the idiot gauges, which show very little if any change.

The gauge does move. You were still mostly in the normal zone so it does not move much if at all.

You may disagree with what the OEM engineers call normal. And I agree it will tend to give less warning as you get to the top of normal with no movement yet. But still you should know when things are working hard.
