What are the techniques for pressing the accelerator when driving an automatic transmission car on a steep slope?

Automatic transmission cars require pressing the accelerator deeply when going uphill, allowing the transmission to downshift. Only when the transmission downshifts can the torque on the tires increase. When climbing a slope, you can also use the L (Low) or M (Manual) gear to keep the transmission in a lower gear. There are three common types of automatic transmissions found in cars: AT (Automatic Transmission), CVT (Continuously Variable Transmission), and DCT (Dual Clutch Transmission). The DCT is based on manual transmission technology and has a structure similar to manual transmissions. The CVT is a relatively simple automatic transmission, consisting of only two cone pulleys and a steel belt. The steel belt can move along the cone pulleys, enabling the transmission to vary speed and torque. The AT transmission is a mature and widely used automatic transmission, containing multiple planetary gears that facilitate speed and torque variation.
I've been driving for twenty years and never panic on steep slopes. The key to driving an automatic transmission uphill is to accelerate smoothly to avoid slipping or rolling back. Start by gently pressing the accelerator to let the car move slowly, then increase the pressure appropriately once you feel the grip is stable. For steeper slopes, shift to L or S gear to keep the RPM around 2000, ensuring the transmission delivers more power. At the same time, keep your eyes on the road ahead and avoid changing lanes hastily. Before the slope ends, gradually ease off the accelerator to transition downhill, using engine braking more to save your brakes. I always remind my friends: check the tire tread depth in advance—worn-out tires are more prone to losing control on wet slopes—safety first. Remember, avoid slamming the accelerator to prevent damaging the transmission or overheating the engine. During routine maintenance, check fluid levels frequently, and ensure the engine is in good condition before tackling a steep slope.
Last time I was driving in the mountains, I had to use my feet flexibly on steep slopes with an automatic transmission car. When starting, gently apply the throttle—don't floor it—to ensure smooth power delivery and avoid wheel spin. If the car feels underpowered, quickly switch to manual mode and downshift to raise the RPM and increase torque. I prefer maintaining a steady speed, pressing the throttle halfway to avoid sudden acceleration or deceleration that could shake the chassis. Stay focused while climbing, keeping a firm grip on the steering wheel to maintain direction. Remember, don’t abruptly lift off the throttle at the end of a steep slope; let the engine decelerate gradually. Based on my experience, cars equipped with hill-start assist are more worry-free, as they automatically prevent rollback on steep slopes, making it easier even for beginners. In bad weather like rain, slightly reducing tire pressure can improve traction.
