What is the reason for the clicking sound when the Prado is in D gear at idle?

[DeJohn]

Prado making a clicking sound when in D gear at idle may be an issue with the idle speed. Introduction to D gear: The D gear in a car is the drive gear, also known as the forward gear, and is the most commonly used gear. When driving normally, the gear selector is placed in the D gear position, and the automatic transmission automatically shifts between gears based on the throttle input. The D gear is located in the middle-rear position of the gear shift console, behind the N gear, and its purpose is to enable the car to automatically select the appropriate gear while moving forward. Main purpose of D gear: When the vehicle is moving forward, the D gear allows the transmission's computer and corresponding mechanical structures to work together to automatically select the appropriate gear in real-time, eliminating the need for manual shifting. This greatly reduces the workload on the driver's hands and feet, improving driving convenience, ease, and comfort.
