What does the M stand for in an automatic transmission car?

In an automatic transmission car, the M gear stands for manual mode. Only cars equipped with a manual mode in a semi-automatic transmission or a simulated manual mode in a CVT transmission have an M gear; regular automatic transmission cars do not have an M gear. Below are the usage methods for the M gear in an automatic transmission car: 1. The M gear in an automatic transmission is the manual mode, which can be engaged directly. Push up once to shift up a gear, pull down once to shift down a gear, and you can start in 2nd gear. 2. When in a high gear, releasing the throttle without pressing the brake will not downshift. If the speed is too low, it will automatically downshift to the appropriate gear. The transmission will not upshift on its own while driving.
I've been driving automatic cars for many years, and this M stands for manual mode, which is a quite practical design. Normally, when driving, you just shift to M and then press the + or - buttons to shift gears up or down without stepping on the clutch pedal, just like operating a semi-automatic. I often use it on mountain roads, locking in a lower gear on steep climbs for strong engine output, preventing the car from rolling back; similarly, I downshift on descents to let engine braking help slow down, reducing brake wear significantly. It's also useful in snow or when towing heavy loads, as the transmission won't shift repeatedly and overheat, plus it saves fuel. Remember, don't use it too frequently—only manually control it when necessary, as overuse can damage the transmission. Combine it with S mode for more driving fun, safety, and economy.
When I was a beginner learning to drive, I also wondered what the 'M' on the automatic transmission meant. Later, I discovered it stands for Manual mode, which simplifies gear shifting—just tap '+' to upshift and '-' to downshift, with the clutch fully automated. The first time I drove our family's old car using M mode, it provided stable starts on slopes without worrying about rolling back; in heavy rain, shifting to a lower gear prevented skidding. I recommend practicing more and combining it with learning hill-start techniques—it adds an extra layer of control for new drivers by preventing the car from misjudging road conditions. Don’t worry about complexity; take your time to master it. It makes daily driving more reassuring and reliably extends your vehicle's lifespan.
