What gear should be used when going down a long slope?

[NatalieRose]

If it is a manual transmission, it is generally recommended to use second or third gear. If it is an automatic transmission, the gear should be shifted to the fixed gear behind the D gear. Here is some related information about gears: Concept: Gears are adjustment devices that regulate the speed and traction (torque) of a car. The lower the gear, the slower the speed, but the greater the car's traction (torque). The higher the gear, the faster the speed, but the smaller the car's traction (torque). Gears are generally divided into two main categories: forward gears and reverse gears. When in forward gear, the car moves forward; when in reverse gear, the car moves backward. Common car gears: Generally, common cars have five forward gears and only one reverse gear. The first forward gear is the starting gear, where the speed is the slowest (0-10 km/h), but the torque is the greatest.
