  3. If the transmission fluid temperature sensor resistance is outside the specified range and the "A/T TEMP" warning light is illuminating, replace the transmission fluid temperature sensor.
    NOTE: The "A/T TEMP" warning light on the combination meter illuminates when the temperature reaches approximately 125°C (257°F) or greater, and then stops illuminating when the temperature drops below approximately 115°C (239°F).
