What is the normal RPM for an automatic transmission?

[CharlotteLynn]

For an automatic transmission, an RPM of around 1800 to 2000 is considered normal. However, the required speed varies depending on different road conditions, and so does the RPM. As long as the engine RPM does not enter the dangerous range, it is generally considered normal. However, it is important to ensure that the RPM matches the current gear position. Otherwise, driving at a low gear with high speed or a high gear with low speed can cause unnecessary damage to the vehicle. An automatic transmission typically refers to the car's automatic gear-shifting mechanism, where the control system of the automatic transmission selects the appropriate gear based on the engine's RPM and load during driving, replacing the driver's subjective judgment and gear-shifting operations. Common automatic transmission positions include Park (P), Reverse (R), Neutral (N), and Drive (D).
