How is the speed controlled in an automatic transmission?

[LeRylee]

Automatic transmission speed control method: You can lightly lift the throttle pedal at the appropriate time, and the transmission will automatically upshift, keeping the engine at a lower RPM at the same speed. Then, by gently pressing the throttle pedal to continue accelerating, the transmission will not immediately downshift. This is a "preemptive upshift, delayed downshift" function designed by engineers to prevent frequent gear changes. Driving an automatic transmission car does not require manual shifting, as the computer automatically shifts gears based on the depth of the throttle pedal press. In other words, controlling the speed in an automatic transmission car simply requires managing the throttle pedal well. Over time, you will naturally develop a feel for the car.
