What are the symptoms of transmission problems?

Transmission problems symptoms: 1. Transmission noise: When the car is idling, driving, or under high-load conditions, abnormal sounds or even loud noises can be heard from the transmission, with dull sounds during gear shifts; 2. Transmission slippage: While driving, when the accelerator is pressed, the engine revs but the car does not show significant speed increase; 3. Transmission fluid leakage: If it's noticeably harder for the car to start, and although the engine RPM increases when the accelerator is pressed during driving, there is no obvious acceleration. The transmission is a mechanism used to change the speed and torque from the engine, fixed or stepped to alter the transmission ratio between the output shaft and input shaft.
Having driven for over 20 years, the most common symptoms of transmission problems are difficulty or delay when shifting gears, and the engine revs up when you press the accelerator but the car doesn't move—that's called slipping. There's also a buzzing or grinding noise while driving, like gears rubbing against each other, which is really unpleasant. When there's a leak, you'll see red fluid seeping under the car, and if not fixed promptly, low oil pressure can worsen the wear. At low speeds, the car may shake violently, and the gearshift might get stuck and refuse to move. The most dangerous scenarios are when warning lights suddenly come on or the car loses power and control, which can easily lead to accidents on the highway. I once ignored these signs and ended up spending a fortune on transmission repairs, so I recommend getting a professional checkup at the shop as soon as you notice anything. Regularly changing the transmission fluid can prevent many issues, keeping your driving safe and comfortable—it's much better than waiting for a major problem to act.
