Throughout automobile history, manufacturers have continuously strived to enhance the driving experience through innovation. Automatic transmission is one such innovation that makes driving convenient. A vast majority now prefers automatic transmission cars.
While they are easier to drive, there are small differences that may spark curiosity. For instance, anyone new to automatic cars would wonder what the letters and numbers on the automatic gear mean.
In this guide, we will explain the numbers or alphabet on the automatic gear shift lever – but before that, you must understand how the automatic transmission works.
WHAT DOES THE P-R-N-D-L MEAN?
Automatic car drivers come across the P-R-N-D-L. The automatic gear shift lever letters and numbers represent a distinctive task or setting. Knowing the details about these letters will help understand the automatic gear shift lever mechanism.
You may also find letters other than the P-R-N-D-L, depending on the car model. P stands for parking, R for reverse, N for neutral, D for driving, and L represents low driving gear. Some cars may have an M that represents a manual shifting option.
Let’s learn more about each letter and number on the automatic gear shift lever.
P: Parking
P in an automatic gear shift lever stands for Park. When the driver moves the gear shift lever to the P position, it engages a locking mechanism in the transmission that prevents the vehicle from moving.
It is essential for safety since it ensures the vehicle cannot roll away when parked. When the car is in the P position, the engine disconnects from the wheels preventing the engine from damage due to the strain of trying to move the stationary vehicle. However, it may happen that the car won’t shift from park mode. Catering to this, you will need to check the transmission and brakes.
R: Reverse
R refers to Reverse. When the automatic gear shift lever is in the R position, it engages the reverse gear in the transmission, allowing the vehicle to move backwards.
Driver must come to a complete stop before shifting to reverse. It will make sure that there is enough clearance behind the vehicle before backing up. Besides, use the rearview and side mirrors to check for obstacles or pedestrians before reversing.
N: Neutral
N stands for Neutral. When the driver moves the automatic gear shift lever to the N position, it disengages the transmission from the engine. That said, it allows the vehicle to roll freely without the engine’s power.
When the vehicle needs to be pushed or towed, or the engine needs to be started, but the car is not moving, the N position helps. It is important to note that the vehicle should be in the N position and not in gear if on a slope or incline. Therefore, the car emergency brakes should be engaged when parked in the N position.
D: Drive
D in an automatic gear shift lever means Drive. It engages the forward gears in the transmission. The transmission will automatically shift between the gears as the vehicle accelerates and decelerates.
The D position is for normal driving in most situations, such as on the highway or in city traffic. The vehicle will move forward when engaged in D when the driver presses the accelerator pedal. Some cars also have the following types of D gear modes:
- D1: It is the First Gear used for maximum torque and pulling power at low speeds, such as when towing a heavy load or driving up a steep hill.
- D2 and D3: These are the second and third gears engaged where more traction or braking is required, such as when driving on slippery roads.
L: Low Drive Gear
L stands for Low Gear or Low Range. It is a mode found on some vehicles with automatic transmissions, usually in combination with a four-wheel drive system. When the gear shift lever is in the L position, the transmission locks into the lowest gear available. It provides maximum torque and pulling power.
In some vehicles, the L mode helps in engine braking when going downhill. When the driver shifts to L, the transmission will downshift to a lower gear, increasing engine RPMs and slowing the vehicle down without the need for constant braking. The low gear is replaced and present as b-gear in hybrid cars, it stimulates regenerative braking and allows smooth travel on steep hills.
M: Manual Shifting Option
M represents the Manual Mode. It gives the driver more control over the transmission’s gear selection. Moreover, it allows them to shift gears manually using paddle shifters.
S: Sporty Drive
Representing the Sports Driving Mode, it provides a more engaging driving experience. The S on the automatic gear shift lever changes the shift points of transmission to allow a dynamic ride. The transmission holds onto gears for longer periods and shifts at higher RPMs. It allows quicker acceleration and sharper throttle response.
A drawback of driving on S for more time is that it may decrease fuel efficiency and cause unnecessary wear and tear on the engine and transmission. However, some vehicles have a feature that automatically shifts the gear to D mode after a while.
These were all the letters on the automatic gear shift lever. From normal driving experience to a dynamic and sporty mode, the automatic transmission ensures a fine experience. However, it is crucial to maintain your transmission as a car won’t go into gear or pose gear issues with a faulty transmission.
Since most modern vehicles feature an automatic transmission, you can explore one for yourself from the listings of used cars for sale in the UAE. Besides, you must be aware of the problems while changing gears to maintain your car on time and avoid these transmission issues.
