If you have ever driven a car with an automatic
transmission, then you know that there are two big differences
between an automatic transmission and a manual
transmission:
- There is no clutch pedal in an automatic transmission
car.
- There is no gear shift in an automatic transmission car.
Once you put the transmission into Drive, everything else is
automatic!
Both the automatic transmission (plus its
torque
converter) and a manual
transmission (with its clutch)
accomplish exactly the same thing, but they do it in totally
different ways. It turns out that the way an automatic
transmission does it is absolutely amazing!

In this feature,
we'll work our way through an automatic transmission. We'll
start with the key to the whole system: planetary gearsets.
Then we'll see how the transmission is put together, learn how
the controls work and discuss some of the intricacies involved
in controlling a transmission.
