An automatic transmission vehicle should maintain a stable RPM of around 1800-2000. Below is an introduction to the RPM of automatic transmissions: 1. RPM reflects the working condition of the engine and is one of the most important parameters of the engine. 2. The tachometer is divided into three zones. The white scale zone represents the safe RPM range; the red scale zone indicates the dangerous RPM range; and the green scale zone represents the most economical operating range for the engine. Below is additional information about engine RPM: 1. When starting the vehicle, the engine RPM will reach 1200-1500. 2. After the engine runs normally, the RPM will drop to around 800. 3. For gear shifting, it is recommended to operate at 2000-2500 RPM.
