In vehicles with an automatic transmission, the letter D often denotes the driveposition, as opposed to N (for neutral), R (for reverse) or P (for park).
There is a picture of a gear in the related link. a gear tooth is one of the things on the outside of the gear that sticks out. This gear has 18 teeth.
Reverse gear
Attached to a gear are many tires. The tires are used the land the aeroplane. That is why it is called landing gear.
A number of gears grouped into a single unit is called 'gear train'.If two gear's in mesh eg, a drive gear and a driven gear also constitute a gear train which are called simple gear train and in the simplest form.simple gear train may have more than two gear's.compound,epicyclic,reverted are some other types of gear train's.
same as drive gear
What are the two d's on the gear shift for>
it is to select "overdrive" gear in transmission. mainly for highway driving. if you have both "D" and "D" with circle around it, use "D" for most driving needs.
Hours.
D stands for Drive.
Overdrive
You ease off on the accelerator and move the gear lever.
You can try "D" but vehicle should downshift automatically to required gear
Park Reverse Neutral Drive 3rd gear 2nd gear Low gear
PI * W * (2 * D - L) * (L - D) Sometimes 3 is used instead of PI, and may actually be closer due to mechanical efficiency. Formula is the same for CID as it is for cm3 (CC's), just a matter if you use inches or centimeters for L, D and W. W = Height of gear (how thick the gear is). D = Diameter of gear. L = Length from edge of one gear to the edge of the other across both gears.
D.
It is the transmission gear selector. P = Park R = Reverse N = Neutral D = Drive 3 = Third Gear 2 = Second Gear L = Low Gear or First Gear Park, Reverse, Neutral, Drive, Third Gear, Second Gear, Low Gear
Driving under normal conditions use "Drive" with circle (highest gear) best fuel economy
