The 1, and 2, in automatic transmission lingo is referred to as "MANUAL LOW", and "MANUAL SECOND". The reason for this is in those ranges, you have what is called "compression braking" available. When you select the DRIVE position under normal operating conditions, the vehicle starts off in 1st gear, as it builds up speed and engine RPM, it then shifts to 2nd gear, and then 3rd gear, and if fast enough (or if equipped), 4th (or overdrive) gear. In the first two gears, when the selector is in the DRIVE position you do not have "compression braking", meaning that when the vehicle slows down to an eventual stop, the engine slows down to idle speed right away, while the vehicle "coasts" to an eventual stop. In the "1" range however, the vehicle will start off in 1st gear, and HOLD (won't upshift to any other ranges). When slowing down in this range, the engine will slow down AT THE SAME RATE AS THE VEHICLE SLOWS DOWN. In the "2" range, the vehicle will start off in 2nd gear and HOLD. The engine will also slow down at the same rate as the vehicle in this selector position. You use these ranges only when putting it under a heavy load, under poor driving conditions (snow or ice), or when descending a VERY steep grade to use the engine to assist the vehicle's brakes in slowing it down, and bring it to an eventual stop. Hope this explains it well enough.

Not to judge your driving ability but if you use D which means the use of all the forward gears and R for reverse you will make out fine. 1 & 2 means first and second gears When the gear shift selector is in D (drive) the transmission will shift through all the forward speed gears automatically, with the best efficiency. As you become familiar with the gear shift selector first (1) and second (2) gears are only used under special driving conditions such as pulling a trailer out of a field or up a very steep hill.

Normally use D for drive.
1 or 2 should be used when the car needs more power (such as going up or down a hill) or when you want to have better traction through less torque (such as in the snow).
However those gears should not be used at high speeds or for other than short times since they can overheat the transmission.

i have automatic geo, it shifts to third gear when i go like 35. So when i race my friend or something i usually put it in gear 1 until 30mph then 2 until 55 mph so i get more rpms (rotations per minute), so there will be more horsepower used. usually just use it when you need extra power if you have a car under 150 horsepower.

Only when you are having problems with your transmission and you need to dry to get it repaired, otherwise never.
