You’re not alone if you’ve ever wondered what those letters and numbers on your automatic transmission shifter mean. Here at Mike Patton CDJR, we get asked about it all the time. So, we thought we’d take a moment to explain the meaning of automatic gear shift letters and numbers.
Basically, the letters and numbers on your shifter indicate the different gears that your car is capable of shifting into. For example, the letter “P” stands for Park, while the letter “D” stands for Drive. We will get into more details about what they mean, but let’s understand how an auto transmission works & how it differs from a manual transmission.
How Does Automatic Transmission Work?
An automatic transmission is a vehicle transmission that can change gear ratios as the vehicle moves, where the driver is free from the hassle of changing gears. A notable difference between automatic and manual transmissions is that automatics use a torque converter instead of the good ol’ clutch.
The torque converter connects your engine to the transmission. It essentially “multiplies” the engine’s torque so that more power can be sent to the transmission, making it easier for the transmission to switch gears.
Now, let’s comprehend the meaning behind those letters and numbers on your automatic transmission.
P is for Park
When parking your car, make sure to put it in P mode. P position locks the transmission and prevents the vehicle from moving. This option is most common when you have to park on a slope.
R is for Reverse
When you want to drive your car in the reverse direction, use R gear. It’s as simple as that! You will be using this option when you have to park in a tight space or back out of the driveway.
N is for Neutral
Just like it sounds, the N position disengages the engine from the transmission so your car can idle without moving. You will most likely use this option when servicing your vehicle or jump-starting another car.
D is for Drive
This is the most commonly used gear, which means your car will move forward. Use this option when you’re ready to hit the road!
The Numbers
The numbers indicate the different gear ratios that the transmission can shift into. The lower the number, the lower the gear ratio. The higher the number, the higher the gear ratio. For example, if you’re on D1 and need more power to climb a hill, you can shift into D2 or D3.
