What is the difference between a 4-speed and a 6-speed automatic transmission?

[OMolly]

4-speed and 6-speed automatic transmissions differ in their speed capabilities, with the 6-speed being faster. Here is a detailed introduction to automatic transmission cars: 1. Overview: An automatic transmission car generally refers to a vehicle that uses an automatic transmission (AT) to regulate speed. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment of timing and gear shifting operations. 2. Other aspects: Automatic transmission cars typically use a hydraulic transmission device to replace the mechanical clutch of manual transmission cars, hence there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward.
