What is the normal RPM for an automatic transmission?
1 Answers
Automatic transmission normally operates at around 1800 to 2000 RPM. The prerequisite for upshifting is acceleration, while the prerequisite for downshifting is deceleration. Higher gears are more fuel-efficient, but this doesn't necessarily mean higher speeds. Lower gears can also operate at high speeds, providing strong power for climbing hills, though they consume more fuel. Whenever road conditions permit, it's advisable to use higher gears. An automatic transmission typically refers to a car's automatic gear-shifting mechanism, where the transmission control system automatically selects the appropriate gear based on engine speed and load, replacing the driver's subjective judgment and manual shifting operations. Most automatic transmission cars have six gear positions, arranged from top to bottom as: P, R, N, D, S, L.
