What are the symptoms of transmission problems?

Below are the symptoms of car transmission problems: 1. Gear shifting impact and shaking while driving: This situation usually occurs in manual transmission cars. When the car is driving above 40 km/h, you can release the clutch directly when shifting gears without causing gear engagement failure or jerking. Therefore, if there is impact and shaking during gear shifting and acceleration, it indicates a problem. 2. High engine speed but insufficient power during driving: If the car delays 2-4 seconds to accelerate after stepping on the throttle, it is largely because the transmission has not engaged the "gear," causing the engine to run at high speed without power. In such cases, the fault cause needs to be checked. 3. Shaking phenomenon during smooth acceleration: Sometimes during acceleration, you may feel severe shaking in the car, which may indicate that the transmission is already damaged. Under normal circumstances, smooth acceleration should not cause jerking or shaking unless there is a problem with the car parts. Therefore, such situations should be checked. 4. Weak starting and slow acceleration: Normally, a car has sufficient power when starting. After releasing the clutch, the car should reach a speed of about 10 km/h. If the car still moves slowly after fully releasing the clutch, it is very likely that the transmission has a problem. 5. Feeling the gear engagement only after 2 seconds: Delayed gear engagement is likely due to burnt forward clutch plates.
When driving, if there's an issue with the transmission, the most common symptoms include rough shifting, especially in automatic vehicles. You may notice delayed response after pressing the accelerator, with the engine revving high but the car moving slowly, almost as if it's slipping, which can be dangerous. Unusual noises like grinding or humming sounds coming from the chassis are also possible, along with noticeable vibrations or instability while driving. Transmission fluid leakage is another warning sign; after parking, you might find a puddle of red or brown fluid under the car. Additionally, pay attention if the dashboard warning light comes on. From my experience, checking the transmission fluid level and quality early on is crucial to avoid more serious repair costs. Ignoring these signs can lead to accidents, especially during lane changes, so regular maintenance is highly recommended.
