What does the first gear mean?

[GeorgeRose]

The first gear is the starting gear, the gear for starting the car. Manual Transmission: A manual transmission is a gearbox that changes the speed and torque transmitted from the engine to the drive wheels, allowing the car to achieve different traction and speed under various conditions such as starting from a standstill, climbing hills, turning, and accelerating, while keeping the engine operating within a more favorable range. Automatic Transmission: An automatic transmission, as the name suggests, does not require the driver to manually shift gears. Instead, the vehicle automatically selects the appropriate gear based on the driving speed and traffic conditions. Generally, an automatic transmission car has six gear positions, from top to bottom: P, R, N, D, S, L.
