What Causes the Clicking Sound in the Transmission?
2 Answers
If the transmission produces a clicking sound, it is caused by the increased gap between the gears. The increased gap between the gears is due to excessive wear, and in such cases, the transmission gears need to be replaced promptly. Below are the relevant details: 1. The transmission requires maintenance. 2. The transmission contains transmission fluid, which needs to be replaced regularly. If the transmission fluid is not changed for a long time, it can lead to abnormal wear of the gears inside the transmission. 3. If the gears experience abnormal wear, the gap between them will increase, resulting in unusual noises from the transmission. It is recommended that car owners replace the transmission fluid on schedule during regular vehicle use.
When I first started driving, I encountered a rattling noise from the transmission, which scared me into stopping immediately to check. Later, I found out it was caused by dirty transmission oil or insufficient oil, leading to gear friction noise, especially noticeable during gear shifts. Another possibility was worn-out bearings, causing unstable creaking sounds. The mechanic said a damaged synchronizer could also cause this, and clutch issues in manual transmissions are more common. Delaying repairs could result in the entire transmission failing, with repair costs ranging from thousands to tens of thousands. I learned my lesson: now I check the oil level every 5,000 km and change the oil regularly to ensure cleanliness. At the first sign of noise, I go straight to a professional shop—no waiting for small issues to become big problems. Early repairs save both hassle and money, and safety comes first.
