What Does “L” Mean On A Gear Shift? Here’s The Scoop
Our vehicles have many different buttons, switches, and gears, and less than half of the drivers know what they are and their functions. One of the most common car features that people use when driving is the gearshift or gear selector. The gear selector consists of many letters that correspond to different transmission settings. Most drivers are likely familiar with the P, D, and R, with P meaning Park, D meaning Drive, and so on.
However, many of you are probably asking: what does the L mean on a gear shift? For a quick answer, the L simply means “Low” or “Low Gear.”
The “L” on a gearshift is a mystery to most people. If you’re like most drivers, you’ve never even used it. However, that doesn’t mean the lonely “L” is useless; far from it. For today’s post, we’ll shed light on this topic and answer the question: what does the L mean on a gear shift? Let’s get to it!
About Your Car’s Gear Shift
The gearshift is a critical component of any vehicle’s transmission system. It’s the central part that transfers torque and engine power, which are used by the wheels to move forward. Gone are the days when most drivers would use manual transmission systems and stick shifts. Nowadays, most modern cars operate with automatic transmissions, quickly detecting via sensors which gear is appropriate for your present driving conditions.
Here’s a quick breakdown of how a car transmission works:
- The engine starts and at the same time spins the part called the crankshaft.
- The crankshaft generates the required power output to put the wheels in motion.
- The car’s automatic transmission will adjust the gearshift and transfer the power from the crankshaft at varying levels of torque.
- The higher generated torque, the more power is transferred to the wheels.
Without the transmission system to regulate the power, your car engine will become unruly. In a vacuum, the explosive power generated by the engine would be too much to start or stop your car. Basically, the transmission ensures that the engine runs at the appropriate rate without going too fast or too slow.

The Gears of Your Car’s Automatic Transmission
You’ve probably noticed that most cars come with a gear shift that has the letters P, R, N, D, and L, also commonly called the PRNDL. Each letter indicates a different state of your transmission and various driving modes. As for the question of what the L means on a gear shift, it means “Low” or “Low Gear.” Thus, the standard PRNDL system reads:
- P = Park
- R = Reverse
- N = Neutral
- D = Drive
- L = Low or Low Gear
As you may know, some of these gears are more frequently used than others. As for the case of the L or Low gear, many drivers haven’t used this mode at all.
Explaining More of the L on a Gear Shift
L refers to low gear, essentially a gear setting of 1 or 2 (if you’re familiar with manual transmissions) for vehicles.
Your car’s automatic transmission won’t normally shift when you’re in L mode. In this mode, the transmission will stick to low gear and cause the engine to take in less fuel and keep the power output low. However, the trade-off is that you get more torque. Therefore, pushing the gas pedal will give your wheels more raw power than speed – something that will come in handy in certain circumstances.
Your car’s transmission passes through low gear when you start the vehicle and ramp up to faster speeds. If you don’t know, your vehicle automatically shifts into low gear. In addition, your vehicle also automatically goes to low every time you park or stop at an intersection and without turning off the engine.
Shifting to low gear is integral to the transmission process because it prevents your wheels from spinning out and losing control. With an automatic transmission, low gear shifting is already taken care of, so you don’t need to keep shifting modes while driving.

When Should You Use the L Gear?
Although your standard Drive position will automatically utilize low gear mode, there are certain conditions where you need the L gear. Due to its greater power delivery, low gear mode is ideal for accelerating or climbing hills. Meanwhile, higher gears are for improved gas economy, higher speeds, and minor wear and tear.
Low gear mode prioritizes the car transmission’s lower gears and may also come in handy for coming down steep hills. This mode prevents the engine from spinning faster even when your foot is off the gas pedal, allowing more engine braking.
Below are some specific situations where you’ll need the L gear:
- For towing trailers, boats, and other vehicles – Keep in mind that Low Gear provides more torque which gives your vehicle more pulling and pushing power. However, it’s always a must to consult your owner’s manual about your vehicle’s towing capability.
- For driving through ice or snow – When you’re in Low mode, you can trust that your car will go slowly but with more power. In slippery conditions like ice or snow, your tires will have a better grip and prevent you from spinning out of control.
- For driving up and down steep hills – Steep inclines and declines like ramps and hills can give too much stress on the engine without switching to low gear. Plus, it’s simply safer to use the L gear for inclinations and declines.
Tips and Tricks: Using the “L” on a Gear Shift
Optimal Use in Hilly Terrains
Utilize “L” mode when navigating steep inclines or declines. It enhances vehicle control and engine braking, which is beneficial for maintaining a safe speed without over-relying on your brakes when going downhill.
Towing and Carrying Heavy Loads
Shifting into “L” can provide additional power and torque when towing or hauling heavy loads, making it easier to start moving and maintain control, especially on inclines.
Enhanced Engine Braking
Use the “L” gear for added engine braking when descending long, steep grades. This can help prevent brake overheating and wear while providing better speed control.
Slow-Speed Maneuvering
In situations requiring precise control at low speeds, such as parking or navigating through tight spaces, the “L” gear can offer finer command over your vehicle’s movements.
Avoid Unnecessary Use
While “L” gear can be beneficial in specific scenarios, using it unnecessarily can lead to increased fuel consumption and engine wear. Only engage “L” when the driving conditions warrant its advantages.
By mastering the use of “L” on your gear shift, you can take advantage of the specialized benefits it offers.

Read Your Owner’s Manual
Hopefully, we’ve answered your question about what the L means on a gear shift. Although you may not use the L mode as much as the others, it’s always good to know that this option is available to you when needed. Ultimately, the L mode is just one of the many tools to improve your driving experience and make it safer.
At the end of the day, it’s always best to read the owner’s manual to have an intimate understanding of your vehicle’s transmission modes. This is because each car may be different, and gear designations may also vary.
Frequently Asked Questions
Q: What does the “L” on my gear shift stand for?
A: The “L” on your gear shift stands for “Low.” This setting is used when you need more power from the engine at a lower speed.
Q: When should I use the “L” setting on my gear shift?
A: The “L” setting is typically used when you’re driving uphill, towing a heavy load, or driving at low speeds over difficult terrain. It keeps the transmission in a lower gear, providing more torque and power.
Q: Can I damage my car by driving in “L” for too long?
A: While it’s not typically harmful to drive in “L” for short periods, doing so for extended periods can put unnecessary strain on your engine and transmission. It’s best to use “L” only when necessary.
Q: What’s the difference between “L” and “D” on a gear shift?
A: “D” stands for “Drive,” which is the normal setting for your automatic transmission when driving. “L” stands for “Low,” which keeps your transmission in a lower gear for more power at lower speeds.
