If the transmission fluid temperature sensor resistance is outside the specified range and the "A/T TEMP" indicator light is illuminating, replace the transmission fluid temperature sensor.
NOTE: The "A/T TEMP" indicator light on the combination meter illuminating when the temperature reaches approximately 125°C(257°F) or greater, and then stops illuminating when the temperature drops below approximately 115°C(238°F).
