What to Do When the Transmission Temperature is Too High?

[FernandoMarie]

When the automatic transmission temperature is too high, do not continue driving. Immediately pull the vehicle over to inspect and allow the transmission temperature to drop to a reasonable range. If the transmission temperature remains abnormal and cannot cool down, call a professional for inspection to prevent potential safety hazards. Causes of excessive automatic transmission temperature include: 1. High engine temperature, which affects transmission cooling, due to engine overload, lack of coolant, lack of engine oil, or severe engine carbon buildup leading to excessive heat; 2. Clogged radiator, preventing the transmission temperature from naturally decreasing—clean the radiator promptly; 3. Clutch slippage, which generates additional heat when lubrication is insufficient, raising the transmission temperature—replace the clutch three-piece set or repair the torque converter; 4. Insufficient transmission fluid—replenish it promptly.
