How to Use the L Gear?

L Gear usage: It is used when going up or down steep slopes. After shifting into L gear, the transmission will maintain a lower gear without upshifting. When the car is in a lower gear, the wheel torque increases, which is more conducive to climbing. When going downhill, shifting into L gear can utilize engine braking to slow down the car. L gear is a low-speed mode; generally, transmissions with L gear have L1, L2, and L3 gears. In this mode, the transmission limits the gear to these lower gears (1 to 3), providing better traction. Typically, automatic transmission vehicles have gears such as P (Park), R (Reverse), N (Neutral), D (Drive), and S (Sport).
From my over twenty years of driving experience, the L gear is most commonly used for speed control. On long downhill slopes where speed can easily get out of control, switching to L gear allows the engine to run at higher RPMs to assist in deceleration and reduce brake wear. Last year during a trip to Huangshan Mountain, the steep slopes were managed entirely by using L gear to stabilize speed and save brake pads. L gear can also be used when climbing steep slopes to increase power and prevent wheel slippage, which is particularly useful when towing a small trailer. However, it's crucial to remember to only shift to L gear at low speeds, such as below 30 km/h, as shifting at high speeds can damage the transmission, especially with the high risk involved. Regular maintenance checks on transmission fluid also help maintain the effectiveness of L gear. In summary, this little trick can enhance driving safety and save on maintenance costs.
As a new driver who has been driving an automatic transmission for only a few years, the L gear was a key point my instructor emphasized during my driving lessons. It's used when going up or down steep slopes—higher engine RPM but slower speed helps avoid the danger of overheated brakes. Shifting to L gear when descending reduces prolonged brake usage, extending the life of the braking system. For example, I tried it on the ramp of my residential parking lot, and the effect was noticeable—much safer. However, remember to only operate it at low speeds; forcibly shifting at high speeds may cause transmission failure. In short, mastering this technique allows new drivers to drive with more peace of mind and convenience.
