What is an Automatic Transmission Car?

[Lonnie]

An automatic transmission car is a vehicle that uses an automatic transmission (AT) to regulate speed. The following introduces the gears of an automatic transmission car: 1. P stands for Park. 2. N stands for Neutral. 3. D stands for Drive, the normal forward gear. 4. 1, 2, 3 are also forward gears, with higher numbers indicating greater torque. Here is an introduction to automatic transmission cars: 1. The control system of the automatic transmission automatically selects the appropriate gear based on the engine's speed and load. 2. It uses a hydraulic transmission device to replace the mechanical clutch of manual transmission cars, eliminating the need for a clutch pedal. 3. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward. 4. When the gear lever is placed in the drive position and the brake pedal is released, increasing throttle and engine speed raises the transmitted torque, propelling the car forward.
