Is High Transmission Temperature Dangerous?
1 Answers
If the transmission temperature warning light comes on, you must stop the vehicle immediately, either idling or turning off the engine. At this point, the transmission is not damaged, but prolonged operation at this temperature may lead to adverse effects such as accelerated aging of transmission fluid, thinning, and reduced lubrication effectiveness. Hence, the warning light alerts the driver. Once the transmission fluid temperature drops back to a reasonable range, the vehicle can be used again. Below is relevant information: 1. Transmission Damage: 90% of transmission failures in cars are caused by high temperatures, which often show no obvious symptoms during use. Prolonged high temperatures can cause internal seals to age, plastic components to become brittle, lubrication performance of the fluid to decline, and shorten the lifespan of electrical components. Therefore, it is essential to regularly monitor transmission fluid temperature and address any issues promptly. 2. Hazards of High Transmission Temperature: Normal transmission fluid temperature ranges between 90-100 degrees Celsius. Prolonged exposure to temperatures above this upper limit can cause severe damage to the transmission. Shortly after starting the car, the automatic transmission fluid (ATF) temperature rises. When climbing hills, operating in high-temperature environments, continuous high-speed driving, or stop-and-go city traffic, ATF temperature can exceed the safe threshold (80°C).
