What are the symptoms of transmission problems?
2 Answers
The symptoms of transmission problems are: 1. The transmission warning light is on; 2. Valve body failure; 3. The transmission does not shift up; 4. There is a strange odor from the transmission; 5. Gear jumping; 6. The car does not move when shifted into gear; 7. Transmission fluid leakage; 8. Long transmission shifting time. The causes of transmission problems in vehicles are: 1. Excessive transmission temperature; 2. The transmission has been used for too long without replacement, leading to fluid deterioration; 3. Water entering the transmission; 4. Large error in fluid level height; 5. Slipping friction plates. The functions of the transmission are: 1. Changing the transmission ratio to expand the range of torque and speed changes in the driving wheels; 2. Keeping the engine rotation direction unchanged, allowing the car to reverse; 3. Using neutral gear to interrupt power transmission, facilitating gear shifting or power output; 4. Allowing the installation of a power take-off.
When driving a manual transmission car, I've found that transmission problems usually have obvious symptoms. You might feel hesitation or increased resistance when shifting gears, difficulty engaging gears after pressing the clutch, or sometimes hear clunking noises. Slipping is also a common issue - the engine revs up but the car doesn't accelerate properly, especially noticeable when climbing hills. Unusual noises like clattering or humming coming from underneath the car are warning signs. Oil leaks leave dark stains on the ground with a burnt smell. Pay attention to these signals during daily driving: excessive vibration when idling, sluggish acceleration response, or suddenly prominent noises. I recommend regular fluid checks - if it appears black or low, replace it promptly. Long-term neglect can lead to complete transmission failure with expensive repair costs. I remember once ignoring early vibration symptoms, which later resulted in a breakdown on the highway costing thousands to fix. Now I've developed the habit of listening for sounds and feeling gear shifts during every drive.
