Is it okay to keep the gear in D when waiting at a red light with an automatic transmission?

[SanIvan]

You can keep the gear in D, and the related explanations are as follows: 1. Reason: When waiting at a red light and stopped, you can choose between two methods—using N gear or keeping it in D while pressing the brake. Keeping the gear in D and pressing the brake will not damage the car because the torque converter in the transmission is equipped with a set of devices. The reaction wheel of the one-way clutch is used to amplify the torque from the transmission crankshaft. When parked for a long time with the engine off, it is best to shift to P gear and engage the parking brake. 2. Supplement: The core function of an automatic transmission is to achieve automatic gear shifting. Automatic gear shifting means that the driver operates the accelerator pedal according to driving needs during the car's movement, and the automatic transmission can automatically shift gears based on engine load and driving conditions.
