What is the usage method of the L gear in a car?

The usage method of the L gear in a car is: simply push the gear lever to the L position. The L gear is a low-speed gear used for climbing or descending slopes. In this gear, the automatic transmission will automatically lock the gear, preventing it from shifting to higher gears, and the transmission will maintain a lower gear without upshifting. Introduction to automatic transmission gears: 1. P gear is the parking gear: used for long-term parking of the vehicle; 2. R gear is the reverse gear: used when the vehicle needs to move backward; 3. N gear is the neutral gear: used when the vehicle is parked for a short time without turning off the engine; 4. D gear is the drive gear: when the gear lever is in the D position, the vehicle will automatically shift gears based on throttle opening and speed data.

As someone who drove manual for over a decade, I was initially confused by the L gear when switching to automatic. Actually, L stands for Low gear, specifically designed for high-traction scenarios. When climbing steep slopes, shifting to L gear increases engine RPM and torque, making ascents effortless while protecting the transmission. It's even more crucial for long descents - during my mountain trip, I relied on L gear's engine braking, barely touching the brakes to prevent overheating. Remember not to forcibly engage L gear above 60 km/h; decelerate first. During rainy seasons, L gear helps prevent tire slippage in flooded areas. Always manually shift back to D gear afterward - unlike my friend who once roared through downtown stuck in L gear.

The L gear is designed by car manufacturers as a backup for special road conditions. When in L gear, the transmission locks between 1st and 2nd gear, turning the engine into a natural decelerator. Once, when I helped a neighbor tow a stalled boat trailer, switching to L gear made the power output noticeably more direct, unlike the frequent gear shifts in D gear that caused unstable towing. The most common mistake beginners make is shifting into L gear at high speeds, which causes the RPM to spike instantly. Remember to operate below 40 km/h, preferably around 20 km/h when switching. Be extra careful with cars equipped with paddle shifters—don’t confuse the downshift paddle with L gear.

Last week, I took my kids to the ski resort and encountered heavy snow—the L gear was a lifesaver! When starting on snow-covered roads in L gear, the tires only slipped slightly twice before gripping firmly. I discovered a trick: switch to L gear in advance for long snowy downhill slopes, and the engine automatically maintains the speed at around 30 km/h, which is safer than tapping the brakes. The simulated manual mode in regular automatic transmissions isn’t as reliable as a true L gear, since the hydraulic locking force differs. I also switch to L gear when crossing waterlogged bridge sections in the rain, keeping a low gear and high RPM to avoid water backing up into the exhaust pipe. Of course, don’t lazily cruise on the highway in L gear—the fuel consumption will make you cry.
