What to Do When Transmission Fluid Temperature Rises?
2 Answers
Solutions for rising transmission fluid temperature: Regularly replace the coolant. Poor performance of the cooling system can lead to many issues. High-temperature transmission fluid exiting the transmission may not be sufficiently cooled before returning, causing inadequate heat dissipation for the high-speed rotating torque converter, resulting in increased load. Generally, a transmission refers to a mechanism used to alter the speed and torque from the engine, capable of fixing or changing the gear ratio between the output and input shafts. The transmission consists of a gear shifting mechanism and a control mechanism, with some vehicles also including a power take-off mechanism. Most transmission mechanisms use ordinary gear drives.
Just encountered a transmission oil temperature warning on the highway, which really scared me. I immediately pulled over, kept the engine running in neutral gear so the transmission pump could continue circulating cooling oil. Covering the radiator with a wet towel can accelerate heat dissipation, but never pour cold water directly on it - that would definitely damage the cooling fins. It's probably due to insufficient oil level or deteriorated oil quality, like when I forgot to change the oil during last maintenance. Always check the dipstick oil level and replace with full synthetic oil every 60,000 km. Clogged cooling grilles are also common - leaves and insect remains can cause overheating if accumulated, so clean them twice a year for safety. For high-performance modifications, installing an independent radiator is necessary as the factory cooling can't keep up.
