See that gate on the left? The part that has the "-" at the top (where god intended it) indicating that if you bump the lever upward your car will downshift? That's a very important part of driving.
It has come to my attention that very few people know how to use this feature of their cars and, as a result, are not driving their cars properly.
Scenario
You're driving on the freeway and you're stuck behind a slow moving vehicle going 10 mph slower than the other lanes. You want to get out from around this vehicle. How do you do that properly in an automatic?
Observe a break in traffic approaching you in the overtake lane. Before it arrives, move the stick from automatic mode into the manual mode and select a downshift. This will cause your car to shift into a lower gear and give you power for overtaking. When the gap arrives, you are already in the proper gear and can simply accelerate into the merge. After you have completed merging, slide the lever back into automatic mode.
How does this differ from what you're used to. What you're used to is using the throttle (a total different control) for modulating the transmission. As a result, you have to mash the throttle to the appropriate depth to try to force the transmission to downshift. When you do that, you not only have to wait for the transmission to shift (losing valuable seconds as the gap passes you by) but you also commit yourself to accelerating toward the vehicle in front of you until you merge. By selecting the gear ahead of time, you have significantly better control and don't have unintended consequences.
Scenario
You have to slow down for a turn, but you know you'll have to get on the gas hard after the turn. How do you do this properly in an automatic?
The answer is that while you're braking you move the lever into manual mode and select a downshift (or two). That way when you're ready to accelerate the power is available for you. If you simply wait until you're ready to accelerate you will have a delay while the transmission tries to find the appropriate gear. The gear selection will be rougher, you will back up traffic behind you (briefly), you will waste fuel, and you may not get the gear you want if your right foot didn't find the right place in the throttle to convince the transmission to select the gear you wanted. After you have completed the turn, slide the lever back into automatic mode.
Scenario
Your car is underpowered and you're going up a long hill. The transmission constantly wants to select a gear that is either too tall, or too short for the hill. As a result, you pop back and forth between 2nd and 3rd gear all the way up the hill. How do you handle this properly in an automatic?
The answer is to slide the lever into manual mode and hold gear 2 (the lower gear that the transmission was selecting). This eliminates needles shifts, inconsistent speed, is less irritating for drivers behind you, is smoother for your passengers, and gives you the power to accelerate more if you need to. Remember that this hill requires this gear and do it in advance next time you're on this hill. After you get up the hill, slide the lever back into automatic mode.
The manual mode of your automatic is your friend. It is a tool. it is not something you need to use for every shift (it would be annoying and pointless to do so), but it is also not something to be forgotten. Develop the technique, and use it in your everyday driving. It should become second nature for you to realize that a given scenario is one of the few times automatic mode is not appropriate, and move naturally into manual mode.
Also, you do not need a manual mode like the one pictured above to make this happen. I have used this technique in a car much like this one:
The button on the side of the gear lever does not have to be pressed for you to slide it forward into D3 for a commanded downshift. There is a reason for this, and the reason is that you're expected to need to do so. When you're done passing, slide it back into D4. It's a simple forward or back motion, no button pressing or unlocking of the lever.
Go forth and develop your automatic driving skills. If you do this already, I applaud you. You are a person who learns how to use a system to its best.
