How to Check Transmission Abnormal Noise?

[MacKimberly]

Methods for checking transmission abnormal noise: The internal structure of the transmission is very complex, and the transmission needs to be disassembled to inspect the faulty part. It is impossible to determine without disassembly. It is recommended that the owner go to a 4S shop or maintenance center for disassembly and inspection to locate the fault. Reasons for transmission abnormal noise: 1. Long-term failure to replace transmission oil: Automatic transmission oil should be replaced every 2 years or 40,000 kilometers, while manual transmission oil should be replaced every 3 years or over 60,000 kilometers; 2. Presence of gear debris in the gears: When the abnormal noise is rhythmic, you can try to increase the throttle. If the noise becomes louder, it can be confirmed; 3. Poor quality of the transmission oil used: Inferior transmission oil has poor performance and is prone to oxidation, forming sludge and residue, which can clog the filter screen and oil passages, increasing friction among internal components of the transmission, leading to abnormal noise.
