What are the buttons on an automatic transmission?

[VonClayton]

The button on the automatic transmission lever is called the gear lock or lock button. More details about automatic transmissions are as follows: 1. An automatic transmission typically refers to a car's automatic gear-shifting mechanism, where the control system of the automatic transmission automatically selects the appropriate gear based on the engine's speed and load while driving, replacing the driver's subjective judgment of timing and gear-shifting operations. 2. A typical automatic transmission car has six gear positions, from top to bottom: P, R, N, D, S, L. The most commonly used automatic gear positions are Park (P), Reverse (R), Neutral (N), and Drive (D).

Over the years of driving automatic transmission cars, I've found the common buttons around the gear lever quite practical. The basics are P (Park), R (Reverse), N (Neutral), and D (Drive), which everyone recognizes. Some models have a small button on the side of the gear lever—that's the shift lock release button, used when you need to move out of P without starting the car, for example. My SUV also has an S (Sport) mode button; pressing it during overtaking makes the RPM soar, which is thrilling. Additionally, the electronic parking brake button and AUTOHOLD auto-hold button are often in this area, allowing you to stop at red lights without keeping your foot on the brake. I recommend checking your car's manual, as button locations and functions vary significantly between brands.

The layout of physical buttons for automatic transmissions is quite deliberate. In addition to the basic gear selection buttons, many vehicles feature a dedicated snow mode button (displayed as a snowflake icon on the dashboard), which is particularly effective for preventing slippage on wet or slippery roads. Off-road models often come with a Hill Descent Control (HDC) button, which automatically controls speed when descending steep slopes. My hybrid car even has paddle shifters behind the steering wheel, allowing manual gear changes that make driving feel like racing. Also, check if there's an O/D (Overdrive) button at the base of the gear lever—it's an overdrive switch that can improve fuel efficiency during highway cruising by turning it off. Electric gear levers are even more complex; for instance, BMW's joystick-style shifter includes an entire rotary knob area for controlling driving modes.

When I first bought a car, I didn't understand all those buttons either. Now I only use a few regularly. The most prominent one on the gear shift is the unlock button - you need to press and hold it to shift gears. There are often paddle shifters near the steering wheel, with the left for downshifting and right for upshifting, especially useful when climbing hills. Near the cup holders, there might be an ECO button that makes throttle response gentler for better fuel efficiency. When reversing, watch the dashboard - models with automatic parking will show a P indicator light. I recommend beginners keep the auto-hold button activated, which automatically brakes at red lights to free your right foot. Remember to avoid accidentally pressing the electronic parking brake while driving - though the system has safeguards, sudden braking can be frightening.
