What to Do When the Car Indicates High Transmission Temperature?
3 Answers
When the car indicates high transmission temperature, you should stop driving and turn off the engine. Continuing to drive can easily lead to serious transmission failures. There are many reasons for excessively high transmission temperature, such as damage to the transmission oil cooler or prolonged non-replacement of transmission oil. Using a circulation machine for oil change can remove over 90% of the old transmission oil, making this method cleaner and more thorough. When purchasing transmission oil, choosing the original product is sufficient. Original transmission oil has been tested by the car manufacturer, ensuring it meets the transmission's requirements under various operating conditions.
When I encounter the transmission overheating warning light, my first reaction is to immediately find a safe place to pull over and not push through to the destination. Continuing to drive could lead to transmission failure or even a fire. Park in a safe area, turn off the air conditioning to reduce engine load, and let the car idle for a few minutes to help cool down. Check the coolant level—if it's low, add fresh fluid, but wait until the engine cools to avoid burns. In summer or on mountain roads, the cooling system might have issues; check if the fan is running and if the radiator is clogged. Once the temperature drops, drive slowly to a repair shop or call for a tow. Once, I neglected to stop and ended up with a burnt-out transmission, costing nearly ten thousand in repairs. Remember, safety always comes first—even small issues require decisive action.
As a friend who has been driving for many years, I believe that high transmission temperature is usually caused by excessive internal friction or poor heat dissipation. For example, hauling heavy loads uphill can lead to overloading, or dirty transmission fluid can affect cooling performance. It could also be due to a faulty cooling fan or clogged oil passages. Letting it cool down after stopping is crucial, while also checking if the oil level is normal and the radiator fan is functioning properly. Avoid aggressive driving to prevent the problem from worsening. Sharing an experience: once during a rainy uphill drive, the warning light came on, and I stopped to clean the mud from the radiator gaps, which alleviated the issue. Even small things require attention, so never delay addressing them.
