Do Automatic Transmissions Have 4 Gears?

[BriellaMarie]

Pure automatic transmissions typically have P, R, N, D, D3/D2/D1. Below is a related introduction to automatic transmission cars: 1. Introduction to Automatic Transmission Cars: These cars generally use an automatic transmission (AT) to regulate speed. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on engine speed and load, replacing the driver's subjective judgment of timing and gear shifting. 2. Operational Characteristics of Automatic Transmission Cars: In modern automatic transmission cars, the driver only needs to control the accelerator pedal. The computer analyzes signals such as engine throttle opening and vehicle speed collected by sensors to automatically control gear shifting or engage different gears. Generally, automatic transmissions may result in some loss of engine power.
