Why is the transmission too hot?

[Smith]

The reasons for transmission overheating are as follows: 1. Dual-clutch transmissions become hot due to the continuous engagement and disengagement of clutch plates; 2. CVT transmissions overheat because of slippage in the steel belt or chain; The functions of a transmission are as follows: 1. To change the gear ratio, expanding the range of torque and speed variation in the driving wheels; 2. To adapt to constantly changing driving conditions, allowing the engine to operate under favorable circumstances; 3. To enable the vehicle to reverse while maintaining the same engine rotation direction; 4. To utilize neutral gear to interrupt power transmission, facilitating gear shifting or power output in the transmission.

I often drive long distances, and transmission overheating is quite common. The reasons usually include frequent gear shifts causing friction and overheating, or insufficient or old transmission oil leading to poor lubrication. Heavy loads like climbing mountain roads or towing can also raise the temperature. When it gets too hot, the car may experience reduced power, increased fuel consumption, or even emit strange odors. Continuing to drive could damage the gear set, leading to expensive repairs. It's recommended to check the oil level and color during regular maintenance—replace it if the oil turns black. Avoid constantly pressing the accelerator in traffic jams and use neutral gear for temporary breaks. Keep the cooling fan clean and free of dust for proper airflow. If any abnormalities are detected, stop and let the transmission cool down—don't push it and risk further damage. Paying attention to these small details will make the transmission more durable, saving money and ensuring safety.

As a car enthusiast, I believe transmission overheating is often caused by poor cooling or fluid issues. For example, clogged oil coolers with accumulated dust, abnormal fan operation, or degraded fluid with insufficient viscosity increasing frictional heat can easily lead to temperature rise during high-speed driving or in congested areas. Over time, this can corrode seals, resulting in oil leaks or costly overall failures. To address this, it's crucial to regularly change dedicated transmission fluid; clean underbody cooling components to remove contaminants; and use manual mode appropriately while driving to reduce automatic shifting frequency. Prevention is better than repair—simple maintenance can avoid major issues. Develop inspection habits to identify and resolve potential problems early.

Frequent transmission overheating in city driving is mainly caused by stop-and-go traffic. When the oil temperature rises, acceleration becomes sluggish, and you may even smell a burning odor. Simply put, avoid frequent hard acceleration or heavy braking; ensure regular maintenance checks for adequate oil levels; use neutral gear for brief rests to aid cooling. Safety first—pull over to let the car cool down when overheating. These small actions protect the transmission.
