What gear should be used for climbing slopes in underground garages?

[McMason]

Gears for climbing slopes in underground garages: 1. For manual transmission vehicles, use 1st gear when climbing garage slopes; 2. For automatic transmission vehicles, use L gear if available, otherwise use manual mode. When climbing slopes, both the driving resistance and the backward gravitational force on the vehicle are relatively large. Lower gears provide greater torque output to the drive wheels, and when the torque reaches a sufficient level, it can be converted into strong thrust and traction, reducing the burden on the engine. The L gear is also a low-speed gear, which restricts the vehicle to low gears, preventing the transmission from frequently shifting up or down automatically. This allows the vehicle to reduce speed and increase torque, making it commonly used when climbing slopes.
