What gear should be used when driving an automatic transmission car up a steep slope?

When driving an automatic transmission car up a steep slope, use the L gear, which is the low-speed gear. The method for starting an automatic transmission car on an uphill is: 1. Press the brake while pulling up the handbrake; 2. Shift the gear to L or S gear and gradually apply the throttle; 3. When the car's forward power is held back by the handbrake, slowly release the handbrake, and the vehicle will start climbing the slope smoothly. An automatic transmission means that the driver does not need to manually shift gears; the vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. The gears of an automatic transmission car are: 1. P gear is the parking gear; 2. R gear is the reverse gear; 3. N gear is the neutral gear; 4. D gear is the drive gear; 5. S gear is the sport mode.
My personal experience driving up steep slopes is that it's best to switch to manual mode or a lower gear. When driving an automatic transmission car, I often find that the D gear lacks sufficient power on steep slopes, with the engine roaring but the speed not increasing. In such cases, shifting into L or S gear can lock the transmission in a lower gear, avoiding frequent gear changes. This results in more stable engine RPM and smoother power output. It's advisable to downshift before climbing the slope; never wait until the car starts rolling back to change gears. Last week, on a winding mountain road with continuous sharp turns and steep slopes, using manual mode fixed in 2nd gear made it much easier, with no shaking or struggling from the car body. Similarly, when descending long slopes, it's essential to engage a lower gear to use the engine's braking force to control speed, preventing the brake pads from overheating and failing.
