How to Judge Gear and Speed Mismatch?

[LaFelicity]

Gear and speed mismatch can be judged as follows: For example, when a car's speed basically reaches 15 kilometers per hour, it needs to shift to 2nd gear for driving. If the car is still in 1st gear when the speed reaches 20 kilometers per hour or more, it is considered a gear and speed mismatch phenomenon. Below is relevant information: 1. Car gears: Generally, automatic transmission cars have 6 gears, namely P gear, R gear, N gear, low gear S gear, and L gear. P gear is for parking, R gear is for reversing, N gear is neutral, and D gear is for driving forward. 2. Working principle: The working principle of an automatic transmission is achieved through an automatic transmission system, which can adjust gears based on the degree of the accelerator pedal and changes in vehicle speed using planetary gears.
