What is the reason why an automatic transmission car does not move when shifted to R gear without pressing the accelerator?

There may be several reasons why an automatic transmission car does not move when the accelerator is pressed: The clutch is not fully engaged; the handbrake is not released; the gear is stuck and not fully engaged; the clutch friction plate is worn out. The correct driving method for an automatic transmission car: Start the engine with the gear lever in P position, and you must press the brake pedal before shifting from P to other gears. When starting, push the gear lever to a lower gear (i.e., 2 or 1, some may have 3), and after the speed increases to a certain level, shift to D gear for normal driving. If cruising at high speed on the highway, you can use the O/D gear to save fuel. When starting, the following points must be noted: Shift gears only after pressing the brake pedal, and check if the gear lever position is correct; when starting over bumps or steps, it is best to press the brake pedal with the right foot, slightly release the right foot while the car is stationary, and slightly press the accelerator pedal at the same time. Lift the right foot immediately after crossing the step and lightly press the brake pedal to prevent severe shaking of the vehicle; do not let the engine speed be too high when starting. Especially in winter, when the air conditioning rapid acceleration device is working, the idle speed may exceed 1500r/min (usually 1000r/min), which can cause strong vibration and gear impact, leading to a sudden start. Therefore, wait for the engine speed to drop before starting.
