Which gear should be used for uphill driving with an automatic transmission?

If the slope is not too steep, press the brake pedal and shift into D (Drive) gear as usual. Here are the detailed instructions: Gradually release the handbrake while pressing the accelerator: After shifting into gear, the car will have power and is less likely to roll back. Move your foot from the brake to the accelerator immediately, applying slightly more throttle than on flat roads. If the slope is too steep, use the handbrake in combination—shift into D gear first, then press the accelerator while gradually releasing the handbrake. If you're still worried about insufficient power, you can shift to S (Sport) gear: The operation is the same as above, but remember to shift back to D gear after climbing the slope, otherwise it will consume a lot of fuel. Shifting into N (Neutral) gear won't help you start on a steep slope—you won't even be able to start on flat ground. To start moving uphill, shift into D gear (Drive gear), and to move downhill, shift into R (Reverse) gear.
I've been driving automatic transmission cars for many years. Generally, using D gear is sufficient when going uphill, as the system automatically adapts to gradient changes, reducing operational burden. However, if the slope is particularly steep or the vehicle is heavily loaded, I switch to manual mode or lower gears, such as shifting to 2nd gear or L gear, to keep the engine at higher RPMs for more torque output and avoid frequent gear shifts that cause jerking. This makes the car more stable and fuel-efficient when climbing. I've noticed many novice drivers rely solely on D gear, but flexible gear shifting on steep slopes can protect the transmission and extend its lifespan. I recommend paying attention to road conditions and shifting gears in advance to avoid future issues. Also, don't forget to use manual mode to lock gears when going downhill to protect the brakes. Good driving habits make the car run smoother.
I believe the key to driving uphill is safety first. For automatic transmission cars, I usually just use the D gear, but if the slope is too steep and the car tends to roll back, I immediately switch to a lower gear or S sport mode to lock the gear and ensure smooth power output. This avoids instability caused by frequent gear shifts and reduces the risk of rolling back, especially when carrying passengers. With over a decade of driving experience, I've encountered many mountain road situations. Once during a heavy rainstorm on a steep slope, I didn't use a lower gear and the car almost slid backward—fortunately, I quickly hit the brakes and avoided an accident. Since then, I've made it a habit to check the slope before selecting the gear. Newer cars now have hill-start assist, which is great, but with older cars, you have to rely on your own observation. Remember to operate smoothly and avoid stomping on the gas pedal like a wild horse, as it can compromise safety.
When driving uphill with an automatic transmission, I usually use D gear for convenience, but on steep slopes, I switch to manual mode and lock in lower gears like 1-2. This keeps the engine running efficiently, reduces strain on the transmission, saves fuel, and protects components from premature wear in the long run. Having driven on various terrains, I've found that choosing the right gear indeed saves money and is more eco-friendly. For example, using a low gear on steep highway climbs prevents excessive wear and fuel consumption. Developing good habits helps the car last longer with fewer repairs. I recommend adjusting gears based on the slope instead of relying solely on automatic functions—extending the car's lifespan starts with attention to detail.
