What does it mean when the atoiltemp light comes on?

atoiltemp light is the transmission oil temperature warning light. The following are the details about the atoiltemp light: 1. When the light comes on: If it appears before inserting the key to start the car, it is part of the vehicle's self-check and will automatically disappear after starting. 2. The meaning of the light: If it lights up during driving, it indicates that the oil temperature in the transmission is too high, and you should pull over to let it cool down. 3. Measures to take: It usually occurs during traffic jams or mountain driving. If it happens frequently, it is recommended to visit a 4S shop to eliminate the issue or upgrade the program. Relevant information is as follows: The existing active safety features in the vehicle's safety system ensure safety and reliability during normal road and off-road driving. When the transmission oil temperature reaches 115 degrees Celsius, a DTC (Diagnostic Trouble Code) will be set and stored to assist in technical analysis.

When driving on mountain roads that day, my AT OIL TEMP light suddenly came on, which scared me into pulling over immediately. This light is actually the automatic transmission fluid temperature warning, indicating the transmission oil temperature has exceeded the limit. Common causes could be continuous uphill driving putting high load on the transmission, or a clogged radiator. I turned off the engine and waited for half an hour before restarting, and the light finally went off. Later inspection revealed the transmission fluid was too low, and topping it up solved the problem. Regular fluid changes are important, and avoid hauling heavy loads in hot weather. If you keep driving with the light on, it could burn out the transmission, costing thousands to repair. For safety, it's best to stop immediately and let it cool down when the light comes on.

Last week while driving on a business trip, the A/T OIL TEMP light suddenly came on, and I was extremely nervous on the highway. I called a technician friend for advice, and he said this light indicates an automatic transmission overheating warning. It could be due to old transmission fluid, a radiator clogged with insect remains, or issues with the transmission itself. He advised me to turn on the heater and let the engine idle for ten minutes to cool down. If the light went off, I should exit the highway at low speed for inspection; otherwise, call a tow truck. Later, the inspection revealed a poor connection in the cooling fan. Now I've developed a habit of checking the transmission fluid color and level during every maintenance check. The repair costs for this can be shockingly expensive.

Last year, my old car also had the 'AT OIL TEMP' light come on. The mechanic said it was due to excessive transmission oil temperature. The main causes include insufficient oil level, deteriorated oil quality, clogged radiator, or prolonged low-speed driving. It's necessary to stop the car immediately to let the transmission cool down and check if the dipstick is within the normal range. If it's an oil issue, simply changing to new oil will suffice; if it's poor heat dissipation, then cleaning the radiator is needed. Continuing to drive could lead to burnt clutch plates and complete transmission failure. That time, it cost me 300 yuan to solve the problem by changing the oil, and since then, I've been keeping an eye on the transmission maintenance schedule.
