When you start your car put in drive with your foot on the brake. Bolted to your crankshaft is a ring gear. A circular plate with teeth around the outside diameter (od).. When you start your car a solenoid pushes the small Bendix into the ring gear to start the engine. Notice when you put the car in drive the car barely creeps forward. The Torque converter is filled with transmission oil. The converter is bolted to the ring gear some people call it a torque plate. Inside of the torque converter there are veins of metal. As the rpms (revolutions per minute) of the motor start to rise the veins spin oil at a higher pressure causing the car to move forward. When the car starts to move the transmission (an automatic gear box) changes gears for you as your speed and rpm of the motor increases. When the rpm of the motor increases the torque converter applies even more oil pressure within itself causing the car to pick up more speed. A governor inside of the auto. shifting box changes the transmission to the next higher gear. This whole cycle repeats itself several times until the auto.trans. is into the last gear which is high gear. Nowadays, some automatic transmissions have as many as eight automatically shifted gears forward. The trans. also includes a reverse gear also. I hope I didn't wear you out.

A transmission is what helps your car switch gears and go forward and backward.
In a "manual" transmission, you have a stick that is usually in between the seats that you have to move from 1st to 2nd to 3rd and so on.
In an "automatic" transmission, the car is simply put into (D)rive and the transmission is controlled by the car to tell it when to shift up or down between the gears.
If you run into a problem with the transmission, the car may take a long time to start moving, it may rev very high before switching gears, or the car may not be able to move in one or both directions depending on the severity.
I had a friend whose transmission died on him and all he could do was drive in reverse. He was contemplating driving to the garage in (R)everse all the way until we convinced him to get a tow truck.
Repairs on transmissions can be very costly ($1000 to $2000). You will probably want to find a shop that specializes in transmission repairs rather than taking it to the dealer (unless it is covered by the warranty), since they usually just ship it out to have it done elsewhere.

Lisa,
In true definition, transmission means the the transfer of force between machines, often with changes of torque and speed. But that doesn't mean much does it? It's more important to learn how transmissions work!
I have attached two links below that describe both manual and automatic transmissions way better than anyone could describe in a single reply. They also have some really good diagrams on the site to help get the basics down.

Automatic Transmission:

Hope that helps :)

the engine is not connected directly to the wheels, meaning the engine doesn't turn the whells in your toyota, but the engine turns the gears in the transmission which in turn turns the wheels. When you are shifting gears in your car, you are engaging different gears in the transmission that will use the power from the engine to turn the wheels in different directions (forward or reverse) OR at different rates.
It's a metal thing that is connected to the engine, so to a non mechanically inclined person it looks like it is all part of the engine.

I cut and copied this from a web site, I hope it helps you out..
A transmission receives a speed and torque input from the engine and delivers a different speed and torque to the final drive and differential. The engine delivers its power to the transmission by means of a rotating crankshaft. The transmission receives this power at its flywheel, a heavy disc that is connected to the crankshaft. The flywheel turns whenever the engine is running. The transmission delivers its output power by means of a rotating shaft.
Almost all transmissions adjust speed and torque by means of rotating gears. A gear is a wheel with projections called teeth around the edges. The teeth mesh (fit together) with the teeth of another gear.

Your car has to switch gears to allow it to change speeds. The transmission does this and is located below and behind the engine.

there are two types of transmissions, automatic and manual transmitions. an automatic changes the gears automaticly when the engine hits the right rpms, with a manual you have to shift the gears with a stick.

the transmission is the part of every car that houses the gearsthat transfer power from the engine to the drivetrain.

Transmission: to transmit power from engine to wheels.

Machinery.
a.transference of force between machines or mechanisms, often with changes of torque and speed.
b.a compact, enclosed unit of gears or the like for this purpose, as in an automobile.
