What Does AT Oil Temp Mean Subaru?

The AT oil temp light on a Subaru is an indicator that monitors the temperature of the automatic transmission fluid. It is crucial to understand what this light means and how to address any potential issues to ensure the longevity and performance of your vehicle.

The automatic transmission fluid plays a vital role in the smooth operation of the transmission system. It lubricates the internal components, helps in cooling, and provides hydraulic pressure for shifting gears. When the AT oil temp light illuminates on your Subaru, it indicates that the fluid temperature has exceeded its optimal operating range.

7 FAQs about AT Oil Temp in Subaru:

1. What causes the AT oil temp light to come on?
The light can come on due to various reasons, including low fluid levels, a malfunctioning temperature sensor, a clogged cooler, or excessive heat generated by the transmission.

2. Is it safe to drive with the AT oil temp light on?
It is not recommended to drive with the light on as it could indicate potential transmission problems. Continued driving may lead to further damage or failure of the transmission.

3. What should I do if the AT oil temp light comes on?
Pull over as soon as it is safe to do so and turn off the engine. Check the transmission fluid level and inspect for any leaks. If the fluid level is low or you notice any leaks, consult a professional mechanic for further inspection.
