The symptoms of insufficient transmission fluid are: 1. Gear shifting feels jerky and not smooth. 2. When pressing the accelerator, the increase in engine RPM does not correspond to the increase in vehicle speed, meaning the RPM rises normally but the speed does not increase, giving the feeling of not being in gear, and starting the vehicle will also be particularly difficult; 3. In severe cases, it can cause the transmission to overheat and damage the transmission. If the transmission fluid is not replaced for a long time, the fluid will become increasingly viscous, affecting heat dissipation and leading to excessively high temperatures. Over time, this will impact the lifespan of the transmission. It is essential to use specialized, original manufacturer transmission fluid and not mix different types. Adding too much fluid can increase resistance during use and wear out components; too little fluid can result in sluggish gear shifting.

I remember when I was driving to the countryside, suddenly I felt the gear shifting was not smooth and got stuck, just like the gears were jammed. After driving for a while, the transmission would buzz loudly and become very noisy. After parking, I noticed small oil stains on the ground, and later found out the oil level was too low after checking. Symptoms also included delayed gear shifting, lack of power when accelerating, and in severe cases, overheating and even a burning smell. The cause might be usual oil leakage or forgetting to change it regularly. I suggest everyone not to ignore these signals, check the oil level with a transmission dipstick in time, and top it up if it's not enough. Otherwise, the wear and tear on the transmission could cost thousands to repair. Make it a habit to check every six months to avoid breaking down halfway and causing delays. Safety first, after all.

From a daily maintenance perspective, the symptoms of insufficient transmission fluid are quite noticeable. Gear shifts become stiff and less smooth, with strong jerking sensations when you press the accelerator. Low-speed turns may produce abnormal noises—annoying creaking sounds. Additionally, transmission fluid temperature may rise, triggering warning lights or emitting strange odors. Low fluid levels lead to poor lubrication, causing internal metal components to wear and fail. Personally, I recommend checking under the hood monthly for any signs of leaks and addressing them immediately. Before adding new fluid, ensure the old fluid and filter are replaced—this saves hassle and protects your car. Neglecting it leads to costly and troublesome repairs, so caution is always wise.

I encountered this issue when I first started learning to drive, and it was really scary. Once, the transmission made a sudden clunking sound when starting from a stop, and shifting gears felt uncomfortably stuck. After driving a short distance, the car felt excessively hot. Later, I asked an experienced driver and found out it was due to low oil. Symptoms also included sluggish acceleration and the dashboard warning light turning red. Beginners tend to overlook these signs, but checking is simple: park on level ground, engage the handbrake, open the engine compartment, and measure the oil level with the dipstick. Regular maintenance can prevent major issues—don’t wait until the noises become severe to fix it, as it’ll cost more and compromise driving safety.
