Car Talk Discussion: Shifting Automatic Transmissions
When to Shift Gears
The most important thing to remember when shifting an automatic transmission is to shift smoothly. Jerking the shifter into gear can damage the transmission.
In general, you should shift gears when the engine reaches the following RPMs:
- 1st gear: 0-15 mph
- 2nd gear: 15-30 mph
- 3rd gear: 30-45 mph
- 4th gear: 45-60 mph
- 5th gear: 60 mph and up
However, you may need to shift gears sooner or later depending on the driving conditions. For example, you may need to shift into a lower gear when driving up a hill or when towing a trailer. You may also need to shift into a higher gear when driving on the highway.
How to Shift Gears
To shift gears, simply move the shifter into the desired gear. The shifter will typically have a “P” (park) position, an “R” (reverse) position, an “N” (neutral) position, and a “D” (drive) position. Some shifters may also have a “L” (low) position or a “S” (sport) position.
To shift into park, simply move the shifter all the way to the left. To shift into reverse, move the shifter all the way to the right. To shift into neutral, move the shifter to the center position. To shift into drive, move the shifter all the way to the right.
If your car has a “L” position, you can use this position to start off from a stop or to drive up a steep hill. The “S” position is used for sporty driving.
