Why Does the Automatic Transmission Make a Clicking Sound When Braking?
1 Answers
Automatic transmission making a clicking sound when braking is due to blockage in the valve body and pipelines inside the transmission, which prevents the sequential regulation and control of oil pressure, leading to abnormal noises. The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also having a power output mechanism. It can be categorized into stepped, continuously variable, and integrated transmissions, featuring functions such as enabling reverse driving, interrupting power transmission, and changing gear ratios. Automatic transmission typically refers to the car's automatic gear-shifting mechanism, where the control system of the automatic transmission selects the appropriate gear based on the engine's speed and load during driving, thereby replacing the driver's subjective judgment of timing and gear-shifting operations.
