Meaning of letters in automatic transmission?

Question

I bought today a Ford Taurus of 1999.
I have never used an automatic type of transmission in my previous cars.
From the top to the bottom the following letters are displayed P N R D(inside a circle) D 1.
P - park
N - neutral
R - rear
D - For sure i know it is the driving position but what is the difference between D (inside a circle) and the normal D?
And 1?

Answer 1

your car has a P that is for mostly when parked around where you live it locks the transmission so the car will not move and if you live in an area that is more or less flat this is all that you would need normally. If you had to park on a hill or something , you may want to turn the wheel into the hill and use the E brake to park with. Revese is for backing up that one is easy. N is for going between Reverse and drive. If you are in town and stay below 40 miles per hour, you would use the letter D while in town. The letter D with a circle around it is for the overdrive while on the freeway only and that is the only reason to use it. when on a long flat stretch of higway it will help save gas by keeping the rpm of the engine lower, but once you get in the hills or mts you would have to get it out of overdrive and into another gear if the car started to slow down.

P - park

N - neutral

D - For sure i know it is the driving position but what is...

Answer 4

D with a circle around it is overdrive, and the regular D is with overdrive locked out. The "1" position is for having the transmission locked in first gear and this is good for climbing steep roads although the only place that I've really needed to use first was to climb mount washington with the car, and to go back down as well to have engine braking so I wouldn't cook the brakes.

Automatic transmission modes In order to select the mode, the driver must move a gear shift lever which can be located on the steering column or on the floor next to the driver. In order to select gears/modes the driver must push a button in (called the shift lock button) or pull the handle (only on column mounted shifters) out. Automatic Transmissions have various modes depending on the model and make of the transmission. Some of the common modes are: Park (P) – This selection mechanically locks the transmission, restricting the car from moving in any direction. A pin prevents the transmission from moving forward (although wheels, depending on the drive train, can still spin freely), it is recommended to use the hand brake (or emergency brake) because this actually locks the wheels and prevents them from moving, and increases the life of the transmission and the park mechanism. A car should be allowed to come to a complete stop before setting transmission into park to prevent damage. Park is one of only two selections in which the car can be started. In some cars (notably those sold in the US), the driver must have the footbrake depressed before the transmission can be taken out of park. Reverse (R) – This puts the car into the reverse gear, giving the ability for the car to back up. In order for the driver to select reverse they must come to a complete stop, and push the shift lock button in and select reverse. Not coming to a complete stop can cause severe damage to the transmission. Neutral/No gear (N)– This disconnects the transmission from the wheels so the car can move freely under its own weight. This is the only other selection in which the car can be started. Drive (D)– This allows the car to move forward and accelerate through a range of gears. The number of gears a transmission has depends on the model, but they can commonly range from 3, 4 (the most common), 5, 6 (found in VW/Audi Direct Shift Gearbox), and 8 in the new model of Lexus cars. D4 – In Honda and Acura automatics this mode is used commonly for highway use (as stated in the manual) and uses all 4 forward gears. D3 – This is also found in Honda and Acura automatics and only uses the first 3 gears and according to the manual it is used for stop & go traffic such as city driving. + - and M – This is the manual selection of gears for automatics with Tiptronic. The driver can shift up and down at their will. Second (2 or S) – This mode limits the transmission to the first two gears, or more commonly locks the transmission in second gear. This can be used to drive in adverse conditions such as snow and ice, as well as climbing or going down hills in the winter time. First (1 or L) – This mode locks the transmission in first gear only. It will not accelerate through any gear range. This, like second, can be used during the winter season, or towing. Some cars when put into D will automatically lock the doors or turn on the daytime running lights.

The d in a circle is overdrive and the 1 is first gear.
