Have y’all e’er though what those letters on an automatic transmission gear shifter genuinely mean? Well then, you’re non alone. There are to a greater extent than than 10 meg automatic-transmission operated cars inwards the USA lone sold each year. The automatic transmission is a to a greater extent than reliable, hydraulically-operated organisation that applies the ability coming through from the engine to your drive wheels. Each missive of the alphabet or position out listed on the transmission gear shift stands for a unique setting or chore for thetransmission. Let’s become into the automatic gear shift pregnant thence y’all would empathize what each missive of the alphabet or position out indicate.
Introducing the PRINDLE
On well-nigh U.S. of A. as well as imported vehicles featuring an automatic transmission are a serial of letters that spell out P – R – due north – D – L. When y’all audio them out, it is phonetically called “Prindle.” In fact, that’s what well-nigh engineers mention the automatic gear shifter configuration to, thence it’s a technical term. Each missive of the alphabet represents an private setting within the automatic transmission. Depending on the type of auto y’all own, it’s as possible that y’all mightiness encounter an “M” or a serial of numbers — probable 1 through 3. To simplify things for you, nosotros volition intermission downwards each missive of the alphabet listed on well-nigh automatic transmissions.

What does the P imply on an Automatic Transmission?
The letters on an automatic transmission are oftentimes described as an private “gear” setting, but that is form of misleading. It’s genuinely an activation setting. The gears within an automatic transmission are hydraulically shifted as well as tin commencement from 3 to nine speeds acre inwards a frontward ‘gear’.
The “P” on an automatic transmission represents the PARK setting. When the gear shifter is inwards park, the transmission ‘gears’ are locked, which prevents the wheels from existence able to movement frontward or backward. Many people utilization the common setting as a brake, which is a main utilization for this transmission setting. However, well-nigh cars too require the vehicle to travel started acre the transmission is inwards the “PARK” setting for security purposes.
What does the R imply on an Automatic Transmission?
The “R” stands for REVERSE, or the gear selected to drive the auto backward. When y’all shift the gear lever from P to R, the automatic transmission’s opposite gear is engaged — which moves the drive shaft backward, allowing the drive wheels to spin inwards ‘reverse’. H5N1 vehicle can’t travel started inwards opposite gear, as it would travel real dangerous to create so.
What does the due north hateful on an Automatic Transmission?
The “N” is a sign that your automatic transmission is inwards NEUTRAL or a gratis spinning mode. This setting releases the gear(s) (forward as well as reverse) as well as allows the tires to spin freely. Most people create non utilization the due north setting except their vehicle engine volition non commencement as well as they necessitate to force it or bring the auto towed.
What does the D hateful on an Automatic Transmission?
The “D” stands for DRIVE. This is when the automatic transmission ‘gear’ is activated. As y’all accelerate, the drive gear volition apply ability to the wheels as well as progressively shift into higher ‘gears’ as the engine RPM reaches the desired level. As the vehicle begins to wearisome down, the automatic drive gear volition down-shift to lower gears. The “D” is too commonly referred to as ‘overdrive.’ This is the travel past times ‘gears’ setting on an automatic transmission. This gear is used on highways or when the vehicle is driving at the same RPM for extended route trips.
If your automatic transmission has a serial of numbers afterwards the “D” those are manual gear settings for the frontward gear performance — amongst 1 existence the lowest gear as well as larger numbers representing higher gears. They tin travel if your regular D gear isn’t working, as well as when going upwards as well as downwards steep hills to render to a greater extent than engine braking.
- D1:Increases torque for hard terrains similar mud or sand.
- D2:Aids the auto inwards uphill climbing, such as hilly roads, or provides a quick engine boost similar to its component on manual transmissions.
- D3:Sometimes shown as an OD (overdrive) push instead, D3 revs the engine for efficient overtaking. The overdrive gear ratio causes the tires to movement faster than the engine spins.
What does the L hateful on an Automatic Transmission?
The in conclusion mutual missive of the alphabet on an automatic transmission is the “L,” which shows the transmission is inwards a depression drive gear. Sometimes the “L” is replaced amongst the missive of the alphabet M, indicating the transmission is inwards a manual shifted option. This setting permits the driver to manually shift the transmission past times using paddle shifters located on the steering wheel, or or thence other activeness (often to the left or right of the automatic gear lever). For those amongst L’s, it’s a setting used for climbing hills or trying to navigate hapless route weather condition — such as existence stuck inwards snowfall or mud.
As each automatic vehicle is unique, or thence of them volition bring dissimilar letters or numbers written on the gear shift lever. It is advised to read as well as review the auto owner’s manual (usually institute inwards the glove box) to travel certain y’all utilization the right gear setting for the right application.
