What are the buttons on an automatic transmission car's gear shift?

[DelLaura]

Automatic transmission cars have the following buttons on the gear shift: 1. Button on the gear lever: Called the shift lock or lock button. This button must be pressed when moving out of P (Park) or shifting into R (Reverse) or P (Park). 2. P (Park) gear: When the gear lever is in this position, the drive wheels are mechanically locked, commonly known as the parking brake. 3. R (Reverse) gear: This gear can only be engaged after the vehicle has come to a complete stop and is used for reversing, such as when parking in reverse or parallel parking. 4. N (Neutral) gear: When the gear lever is in this position, the transmission does not engage any gear, and there is no power output. 5. D (Drive) gear: When the gear lever is in this position, the transmission automatically shifts up and down within the engine's RPM range. 6. S (Sport) gear: This is also a forward gear (sport mode). When the gear lever is in this position, the transmission automatically shifts up and down at higher engine RPMs compared to D (Drive) gear.

I've been driving for over a decade and have encountered many buttons on automatic transmissions. The most common small button next to the gear shift is the shift lock button, which can't be pressed without stepping on the brake, preventing accidental operation. Some cars also have a sport mode button labeled S, which gives an instant power boost for highway overtaking. There's also the low gear L, especially useful for climbing steep hills or descending long slopes. My family's SUV has a snow mode button on the left side of the gear shift, which provides better stability when slipping occurs in winter. Additionally, there's the manual mode button, marked with M or plus/minus signs, allowing you to shift gears manually for a more engaging driving experience. Newer models now come with electronic parking brake buttons and auto-hold keys, making it convenient at traffic lights without needing to keep the brake pedal pressed. Button locations vary by brand, so it's advisable to consult the manual to familiarize yourself with your car's specific features.

I remember being completely clueless the first time I drove an automatic transmission car, and only later did I figure out those buttons around the gear lever. The most noticeable one is the button with an arrow - you have to press it before shifting gears. Some cars design the sport mode as a separate button, like the S-gear button I saw on my friend's Hyundai. Other models have +/- buttons on the side of the gear lever for manual shifting, which is particularly useful when overtaking. My Nissan has a button with a slope symbol that automatically limits speed when pressed during long descents. Nowadays, new energy vehicles are even more extreme, with electronic gear levers surrounded by a row of integrated buttons, even making the handbrake automatic. I'd recommend beginners actually sit in the car and feel around - just listening to others can be confusing.

From a mechanical perspective, these buttons are quite interesting. Every automatic transmission vehicle must have a shift lock button, which works with the brake sensor to ensure safe gear shifting. The sport mode button essentially alters the shift logic to increase engine RPM. The L gear button is equivalent to limiting the highest gear to boost torque output. The M button switches to manual-automatic mode, allowing the ECU to respond to manual commands. Nowadays, high-end cars also feature a hill descent control button that uses ABS to automatically regulate speed. Some buttons come with backlighting for ease of operation at night. Their placement is also carefully considered, balancing accessibility with prevention of accidental presses.

I found that button functions largely depend on the car model. Regular family sedans typically have just two: the gear shift button and the sport mode button. SUVs and off-road vehicles add an L gear button to handle complex road conditions. Performance cars prefer to add paddle shifters on the steering wheel instead of manual buttons. Hybrid models often feature an additional B gear to enhance energy recovery. Electric vehicles have the simplest buttons, commonly using an electronic rotary knob for shifting. Regardless of the type, the most important is still that shift lock button, which must be pressed every time shifting from P gear. In daily use, you might not touch other buttons for a long time, but you need to know where they are when needed.

Driving my dad's old Crown compared to modern cars is quite a contrast. The old car's gear shift was just a simple lever, single-function but reliable. Nowadays, new cars have so many buttons it's dizzying—last time I drove my nephew's Tesla, I had to shift gears via the touchscreen. Among traditional buttons, the most technically advanced is the M-mode shift button with gear indicator lights, clearly showing the current gear. The snow mode button, which starts in second gear to reduce wheel spin, is quite scientific. My personal advice: remember three core buttons—always use the shift lock, engage sport mode for highways, and use L-mode for mountain roads. The rest can be used based on personal preference.
