Why does the Honda Civic automatic transmission make noise when starting?
2 Answers
The reason why the Honda Civic automatic transmission makes noise when starting is mainly because the speed of releasing the brake is too slow when starting, which is a common problem with many automatic transmission cars. When the brake pedal is slowly released, the engine already has enough power to drive the car forward, but the brake is not completely released. As a result, the moving wheels are held back by the brake system, naturally causing noise, which is a normal phenomenon. Car starting techniques are as follows: Starting on a flat road: The key action for starting on a flat road is the coordinated cooperation of the clutch and the accelerator, that is, the clutch-accelerator coordination. After lifting the clutch pedal to the engagement point, slowly lift it further while gradually pressing down the accelerator pedal. Starting on an uphill slope: The key to starting a car on an uphill slope is to overcome the uphill resistance and prevent the car from rolling backward. In addition to the essentials and operations of starting on a flat road, it is also necessary to pay attention to the close coordination of the parking brake lever, clutch pedal, and accelerator pedal operations.
The Civic makes abnormal noises when starting in automatic mode? I've encountered similar situations before, which might be friction sounds caused by worn clutch plates or metallic impact sounds due to transmission issues. The noise is particularly noticeable during startup, usually because the load on the drivetrain increases, and aging bearings may also produce creaking sounds. Personally, I recommend first checking the transmission fluid level; if the oil is too dirty or insufficient, it can increase friction between components, leading to noise. Also, don’t forget to inspect the suspension brackets—if the springs are loose, body vibrations can cause abnormal noises. In daily use, avoiding sudden starts or prolonged idling can reduce mechanical stress. If the abnormal noise persists, it’s best to have it diagnosed at a reputable repair shop to prevent minor issues from turning into major repairs. Cars like the Civic are prone to such faults when driven frequently in urban areas, so don’t delay addressing them.
