What are the introductions to vehicle gears?

[MicahRose]

Vehicle gears are as follows: 1. Pure automatic transmission gears: Pure automatic transmissions generally have P, R, N, D (D3), D2, and L. P is the parking gear, R is the reverse gear, N is the neutral gear, D is the driving gear, and D (D3), D2, and L are also driving gears, but with slight differences from the D gear. These gears do not shift based on engine speed; their purpose is to allow the vehicle to have higher engine speed at the same speed, providing greater power and torque output, typically used during high-speed overtaking and climbing steep slopes. 2. Manual-automatic transmission gears: Manual-automatic transmissions have P, R, N, D, and M/S gears. The P, R, N, and D gears are no different from those in a pure automatic transmission. The difference lies in the M/S gear, which is the manual mode gear. When placed in this gear, pushing the gear lever in the + direction shifts up, and pushing it in the - direction shifts down. The gear lever can be pushed directly without pressing the brake.
