What Gear to Use for Long Uphill and Downhill in an Automatic Transmission Car?

[NathanDella]

For automatic transmission vehicles when going downhill, you can use gears such as L, M, S, 1/2/3, or +/-. Below is an introduction related to automatic transmission cars: 1. Overview: Automatic transmission cars generally refer to vehicles that use an automatic transmission (AT) to regulate speed. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment of timing and gear shifting operations. 2. Others: Automatic transmission cars typically use a hydraulic transmission device to replace the mechanical clutch of manual transmission cars, hence there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward.
