MyVans Your Vehicle Solution Subaru cars are known for their sturdy build and reliability. But like any other vehicle, Subarus may experience issues that require attention. One common problem that Subaru owners may face is the AT oil temperature warning light. This light indicates that the transmission fluid temperature is too high or too low, and it needs immediate attention to avoid further damage to the vehicle.
What Is the AT Oil Temperature Warning Light?
The AT oil temperature warning light is a warning light that indicates a problem with the transmission fluid temperature. The transmission fluid is an essential component that helps lubricate and cool the transmission system. If the transmission fluid temperature is too high or too low, it can cause damage to the transmission system, resulting in expensive repairs.
What Causes the AT Oil Temperature Warning Light?
The AT oil temperature warning light can be triggered by various factors, including:
- Low transmission fluid levels
- Damaged or worn-out transmission fluid
- Faulty transmission fluid temperature sensor
- Blocked or clogged transmission fluid cooler
How to Fix the AT Oil Temperature Warning Light on Your Subaru
If you notice the AT oil temperature warning light on your Subaru, it’s essential to take immediate action to prevent further damage to your vehicle. Here are some steps you can take to fix the problem:
Step 1: Check the Transmission Fluid Level
The first step to fixing the AT oil temperature warning light on your Subaru is to check the transmission fluid level. Low transmission fluid levels can cause the transmission system to overheat, triggering the warning light. Check the transmission fluid level using the dipstick, and if it’s low, top it up to the recommended level.
Step 2: Check the Condition of the Transmission Fluid
The condition of the transmission fluid can also cause the AT oil temperature warning light to come on. Check the transmission fluid for any signs of wear or damage. If the fluid is dark or has a burnt smell, it may be time for a fluid change.
Step 3: Check the Transmission Fluid Temperature Sensor
If the transmission fluid level and condition are okay, the next step is to check the transmission fluid temperature sensor. The sensor helps monitor the transmission fluid temperature and sends signals to the car’s computer system. If the sensor is faulty, it may trigger the warning light. A mechanic can diagnose and replace a faulty sensor.
Step 4: Check the Transmission Fluid Cooler
If none of the above steps work, it may be time to check the transmission fluid cooler. The cooler helps regulate the temperature of the transmission fluid. If it’s clogged or blocked, it may cause the transmission fluid to overheat, triggering the warning light. A mechanic can check and clean the transmission fluid cooler to fix the problem.
Conclusion
The AT oil temperature warning light on your Subaru is a critical warning that requires immediate attention. Ignoring the warning light can cause severe damage to your vehicle’s transmission system, resulting in expensive repairs. If you notice the warning light, follow the steps outlined above to fix the problem. If you’re not comfortable performing the repairs yourself, take your vehicle to a qualified mechanic.
