Best Answer

Overdrive. The transmission contains a final section that causes the output to turn at a faster rate than the input. When this happens it is refered to as "overdriving". Very common in new vehicles as once at speed the overdrive kicks in and the rpms become lower to keep the car at the same speed, hence increasing gas mileage. Press lightly on the accelerator and you can feel the overdrive gear kick out and the car then begins to accelerate. The circle d refers to overdrive gear in your transmission , which is less than a 1:1 or direct drive gear ratio. This gearing lowers your engine rpm for fuel economy but effects pulling power of your vehicle.In a truck there is normally an overdrive disconnect switch on the end of the shift lever.

What is a d in circle on the dash of my Lincoln aviator?

The D with a circle will allow the transmission to shift into overdrive which reduces engine RPM"S and will conserve fuel when on a highway cruise.


When inserting a column if you select column D where will the new column be inserted?

The inserted column will push column D to the right and become the new column D. The original column D will become column E, and so forth.


What is the d in a circle for on the gearshift do you drive in that or the plain d?

The D with a circle will allow the transmission to shift into overdrive which reduces engine RPM"S and will conserve fuel when on a highway cruise. The D without a circle will not let overdrive engage. this is useful when traveling on hilly terrain where overdrive tends to engage and disengage. I usually drive in the circle mode unless i am climbing uphill and the transmission keeps downshifting and upshifting. Rule of thumb: Circle D on the highway, and plain D in the city


When you insert a column where does it automatically go?

The column will go where the currently selected column is, pushing all columns to the right. So if column D was selected and you inserted a column, column D would become column E and the inserted column would now be column D.The column will go where the currently selected column is, pushing all columns to the right. So if column D was selected and you inserted a column, column D would become column E and the inserted column would now be column D.The column will go where the currently selected column is, pushing all columns to the right.

What do the number 2 and 1 mean in the 1987 Chevy S-10 Gearshift.and the D with a circle is for driving on the freeway right?

The "2" means that the transmission will only shift up to 2nd gear and will just rev the motor higher the faster you go. The D with a circle means Overdrive. And yes this is what you use for any normal driving.

What is mean by pi in mathematics?

If you mean pi as in 3.14159... I can answer. Pi is a relationship that compares the circumference of a circle to the diameter of that same circle by division. In any circle, if you divide the length of the circumference of that circle by the length of its diameter you will get 3.14159... or pi. This can be very helpful to know because it is much easier to measure the diameter of a circle than to measure the distance around the circle (circumference). If you multiply the diameter by 3.14159... you will find the circumference. If C = circumference; D = diameter; pi = 3.14159 theses are some useful formulas: C = D X 3.14159 or D = C / 3.14159 or 3.14159 = C / D
