Will an Automatic Transmission Car Roll Back on a Slope?

[JuniperFitz]

Automatic transmission cars are prone to rolling back when encountering steep slopes, while on gentle slopes, the occurrence of rolling depends on the vehicle's performance. Below are detailed introductions to the gears of an automatic transmission car: 1. The R gear is the reverse gear. Engaging this gear connects the hydraulic system's reverse oil circuit, causing the drive wheels to rotate in reverse for backward movement. Do not forcibly shift to the "R" gear when the vehicle is not completely stopped, as this may damage the transmission. 2. The N gear is the neutral gear. When in neutral, the planetary gear system idles and cannot output power. 3. The D gear is the drive gear. When the gearshift lever is in this position, the hydraulic control system automatically connects the corresponding forward gear oil circuit based on throttle opening and vehicle speed signals. It can automatically shift up or down with changes in driving speed, achieving automatic transmission functionality. 4. The P gear is the parking gear. It uses a mechanical device to lock the rotating parts of the car's tires, preventing the vehicle from moving.
