The transmission is how the car changes gears. It allows a car to climb up steep hills and move quickly. Sometimes it is called the gear box. The transmission helps to transfer the energy from the engine to the wheel axle, where energy is applied to the wheels of the car. 
Most cars have an automatic transmission, but some cars are manual transmission. You can find cars for a cheaper price that have a manual transmission (stick shift) and many sports cars also use these.
The manual transmission is cost efficient, but when compared to the modern automatic transmission, the automatic transmission may save money in fuel costs. Still, the manual transmission is cheaper and easier for mechanics to work on.
To keep the transmission working well inspect the transmission fluid levels every month and its color about every 6 months. After about 30,000 miles of driving is a good time to change the transmission fluid depending on the car. A sealed transmission will usually last quite a bit longer.
