How to Shift Gears in an Automatic Car While Driving?
2 Answers
To shift gears in an automatic car while driving, simply move the gear lever from D to the desired position such as L without the need to stop or brake. If you need to activate the manual shifting function while driving in D, move the gear lever from D to M, and then use the M+ and M- positions to shift gears. Shifting from D to M also does not require stopping or braking. An automatic transmission typically refers to a car's automatic gear-shifting mechanism, where the control system of the automatic transmission selects the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment and manual shifting operations. Generally, an automatic car has six gear positions, from top to bottom: P, R, N, D, S, L.
When driving, shifting gears while in motion requires careful handling. Automatic transmission cars usually stay in D (Drive) gear, where the vehicle shifts gears automatically. However, if you want manual control—such as for better traction when climbing or descending steep slopes—most models offer a manual mode or S (Sport) gear position. While maintaining a steady speed, gently push the gear lever in the + or - direction to shift gears, avoiding excessive force or rapid switching. Importantly, never shift directly from D to P (Park) or R (Reverse) at high speeds, as this can damage the transmission or even cause loss of control. I always make it a habit to operate at low speeds or with the brake firmly pressed to prioritize safety. Mastering this technique makes mountain driving smoother, especially in rain or on steep slopes—manually downshifting helps decelerate, saves brakes, and extends the car’s lifespan. Familiarizing yourself with the vehicle manual to understand gear positions is key. The longer you drive an automatic, the more you realize such small maneuvers can boost efficiency.
