What are the symptoms of a damaged transmission input shaft?
4 Answers
The symptoms of a damaged transmission input shaft include: a grinding or rustling noise from the transmission, elevated temperature, and in severe cases, displacement of the transmission shaft, which can affect power transmission and prevent the vehicle from starting. Below is more information about the transmission input shaft: 1. If you hear abnormal noises from the transmission area while the car is idling or driving, possible causes include: insufficient or deteriorated transmission fluid; worn, loose, or damaged transmission bearings; bent transmission shaft; or abnormal gear engagement. 2. The transmission is a crucial component of a car. Modern transmission technology is highly advanced, and as long as the driver does not frequently engage in aggressive driving, the input shaft of the transmission is unlikely to be damaged.
I once had a broken transmission input shaft while driving, and it was truly a nightmare. The car made a continuous rattling noise upon starting, especially louder during acceleration, like metal grinding. Shifting gears was particularly difficult, with noticeable jamming when engaging, and the whole body shook when the clutch engaged. The power output was also unstable, sometimes completely powerless during acceleration, as if the throttle was floored. This is usually caused by shaft wear or insufficient lubrication. If not repaired in time, a broken shaft can lead to the entire transmission being scrapped, with repair costs running into thousands of yuan. It's advisable to have the transmission oil and internal wear checked at a professional shop if you hear any abnormal noises. Regular maintenance with high-quality oil can extend its lifespan. In short, a faulty input shaft causes many issues, so don’t delay in getting it fixed.
Last time my car had an issue with the transmission input shaft, and the symptoms were very obvious. While driving, I often heard a rattling noise, especially when turning at low RPMs. Gear shifting became extremely rough, frequently getting stuck when shifting into drive or reverse, requiring multiple attempts. The car also vibrated during acceleration, with the steering wheel shaking. Worse yet, there was a sudden loss of power at high speeds, which really startled me. The cause of this failure is usually due to shaft wear or cracks, possibly from long-term wear or poor oil quality. I immediately took it to the dealership for inspection, and the technician said a damaged shaft could affect the entire power transmission. After repairs, the car returned to normal. Remember, if you notice similar issues, don't hesitate to get it fixed—safety first.
While driving, I noticed that the transmission input shaft is damaged. The symptoms can be simply described as loud noises and difficulty in shifting gears. There's a clicking sound after starting the engine, which gets louder when the accelerator is pressed harder. When shifting gears, it often feels stuck, and sometimes the gear won't engage. The car vibrates severely, especially when starting on flat roads. This could be due to a cracked shaft or insufficient lubrication. Getting it repaired promptly can save trouble.
