Fan clutch failures generally start to couple less and less
water pump shaft RPM's...till they almost free wheel
Since a failing unit still couples, there is enough air being pulled to take care of low demand...but...as the demand for more air goes up...it can not a accommodate...therefore the coolant can not reject enough BTU's and the engine heats up
Lowest cost component or system first, else tossing money away....till you get to that lower cost thing...
I agree this could well be the issue. Engine temperature can stay at 190 but the transmission fluid cooler in the radiator is on the cool side of the radiator. So the water exiting the radiator might be cool enough for the engine but not cool enough to absorb enough from the transmission. Partially restricted radiator could do same.
