What gear should an automatic transmission car use when climbing a steep slope?

An automatic transmission car should use the L gear, S gear, or M gear when climbing a steep slope. An automatic transmission car uses a computer to control hydraulic oil to push pistons for gear shifting based on throttle size, vehicle speed, and throttle opening. It automatically selects the appropriate gear according to driving speed and traffic conditions, allowing it to independently control the gear to better match the engine speed with the gear. The gears of an automatic transmission are as follows: P gear is the parking gear and also the starting gear; R gear is the reverse gear; N gear is the neutral gear; D gear is the drive gear, also known as the forward gear; S gear is the sport mode; L gear is the low-speed gear, which uses an automatic transmission and planetary gear mechanisms for shifting, automatically adjusting gears based on the degree of throttle pedal and changes in vehicle speed.
