Which gear should be used when driving an automatic transmission car uphill?

Automatic transmission cars can use D gear or S gear when going uphill. The following is a detailed introduction to gear selection for different road conditions: 1. Uphill: This type of road section requires high torque intervention, and you can use "D-" to downshift. However, sometimes when there is sufficient power, it is also necessary to use "D+" to upshift to prevent power waste and damage to the engine and transmission. When encountering steep slopes, even after downshifting, you may still experience insufficient vehicle power. In this case, use the S gear (sport mode). 2. Downhill: Use "D+" to shift up to D2 or D3 gear, which can restrain the engine to achieve a braking effect. Generally, gears 2-3 are sufficient for moderate slopes, but when encountering steep slopes, pay attention to switching to gear 1. If the vehicle starts sliding faster, you should also use "D-" to downshift and control the vehicle.
When driving an automatic transmission car uphill, I always prioritize using the L gear or lower gears. Having driven for over a decade, especially in mountainous areas with many steep slopes, not using lower gears can easily cause the car to roll back or lack power. The L gear allows the engine to rev higher, providing more sustained power. If the car doesn't have an L gear, I use the S gear or manually shift to a lower gear. I still remember last year during a trip when a garage ramp was very steep—after switching to L gear, the car climbed steadily without suddenly stalling. Safety first: don't stomp on the gas pedal when going uphill to avoid overheating the engine; it's also good to do a quick check on the transmission before setting off. Years of driving experience have taught me that these small details can save a lot of trouble, protecting the car and preventing accidents.
As a beginner learning to drive, I often use the S gear or manual low gear when driving an automatic transmission car on slopes. My instructor taught me to maintain high engine RPM when going uphill, as lower gears help increase power to prevent rolling back or insufficient power. During practice, I tried multiple times at the garage entrance and found that switching to S gear made the car accelerate more steadily without sudden speed changes. I recommend beginners practice on flat ground to simulate uphill conditions first—safety is the top priority. Before driving, check the manual as gear settings may vary by model; for example, in my car, S gear stands for Sport mode, which also works. Be careful not to focus solely on shifting gears and neglect road conditions when climbing hills, as this can easily lead to accidents.
As an off-road enthusiast, I rely on manual mode or low gears when driving an automatic transmission up steep slopes. On rugged mountain roads, the vehicle must deliver strong power output, otherwise it's prone to rolling backward or losing traction. Manually shifting to 1st or 2nd gear while maintaining high RPM proves most effective, making climbs much smoother. I recall one wilderness expedition encountering a massive incline - shifting gears allowed steady passage. For safety, always ensure good tire grip before ascending and avoid braking midway on slopes; if the vehicle rolls backward, act promptly. These practical and reliable techniques were honed through numerous off-road adventures.
