My Toyota Prado instrument panel will trigger A/T OIL TEMP on when climbing long hill. As the car climbing, the radiator temperature remains the same. Once I drive down hill, the A/T OIL TEMP indication ultimately will disappear. I believe this indication is genuine but I don't know what is the root cause problem. I with your experience can consult me for a solution. Thank You.

Condition of fluid may have importance. Replace filter and flush trans fluid and see if that works

Automatic transmission fluids had been replaced including the filter but the problem still persist. I suspect radiator need to be change also. What is your opinion?

I would probably ignore it.
If the company has a directive for this issue, it will be "google-able"
