What gear should an automatic car be in when going uphill?

An automatic car should be in L gear when going uphill. The main gears of an automatic car include: P gear, R gear, N gear, D gear, L gear, and OD gear. Gear introduction: 1. P gear is the parking gear, used when the engine is off or the car is stationary; 2. R gear is the reverse gear, which can only be engaged when the car is completely stationary; 3. N gear is the neutral gear, used when the car is temporarily stopped, but the brake must be applied on slopes; 4. D gear is the drive gear, used for general road driving, automatically shifting to the appropriate gear based on road conditions and load; 5. L gear is the low gear, also known as the climbing gear, which limits the range of automatic shifting to increase torque and output greater force; 6. OD gear is the overdrive gear, used for high-speed driving to achieve fuel efficiency.
After driving for so many years, I've found that using the D gear is usually sufficient when driving an automatic transmission car uphill. On gentle slopes, a light press on the accelerator is enough to climb smoothly, as the transmission will automatically adjust the gears. However, when facing particularly steep slopes, I switch to L gear or manual mode. This keeps the car in a lower gear, giving the engine more power and preventing stalling or rolling back halfway up. Once, during a mountain drive, I didn't pay attention and tried climbing in D gear. The transmission kept trying to shift to higher gears, forcing me to press the accelerator harder, and the car almost stalled. Remember to press the brake firmly before starting uphill to avoid sudden sliding. For prolonged uphill driving, occasionally using the S gear can save some fuel and reduce transmission wear.
