Will an automatic transmission car move when in D gear without pressing the accelerator?
2 Answers
Automatic transmission vehicles will move forward when in D gear without pressing the accelerator. The specific situations are as follows: 1. D gear is the forward gear. It is the most common gear in automatic transmission vehicles, usually located in the middle-rear position of the gear shift console, behind the N gear, designed to automatically select the appropriate gear while the car is moving forward. 2. If driving on an upward slope, without pressing the brake and with a steep slope angle, even if the car is in D gear, it may not move forward and could remain stationary or even roll backward. 3. On a downward slope, without pressing the brake, the car will definitely move forward. 4. If you need to stop and wait, it's best to shift the car into P gear.
I've been driving an automatic transmission car for ten years. After shifting to D (Drive) gear without pressing the accelerator, the car actually moves slowly, which is called the creep effect. When the engine is idling, the torque converter automatically transmits power to the wheels, maintaining a speed of about 5 kilometers per hour, allowing easy movement on flat ground. I rely on this feature to save effort in congested urban areas, as it's particularly comfortable not having to keep my right foot on the accelerator constantly. However, extra caution is needed on slopes: uphill, the creep might be insufficient, causing the car to roll back, while downhill, the car may accelerate, requiring brake control. Beginners might get startled by this, so it's advisable to develop the habit of pressing the brake when shifting gears. If the car doesn't move at all, it could indicate a transmission system issue, such as unstable oil pressure or a faulty sensor, and it's essential to get it checked at a repair shop promptly.
