Why does the Honda 5AT transmission make abnormal noise at idle?
1 Answers
Honda 5AT transmission idle noise is caused by long-term failure to change the oil or using inferior oil. Long-term failure to change the oil: Not changing the oil for a long time will cause the transmission oil to become thicker and insufficient in fluidity, resulting in direct friction between components without a protective layer, thereby exacerbating the wear of mechanical parts inside the transmission and causing abnormal noise. Using inferior oil: Because inferior oil has poor temperature resistance and is prone to oxidation reactions, forming sludge and oil residue, which can clog the filter screen and oil passages, increasing friction between internal components of the automatic transmission, leading to abnormal noise when the vehicle starts.
