A modern automatic transmission is a complex piece of machinery in it’s own right. But it is part of a complex assembly that makes your car move, namely your car’s power train.

What Makes Up an Automatic Transmission?
According to this article excerpt from ABOUT.COM:
“While there are many, many little parts inside, your transmission is essentially made up of a few key parts of systems.
Bell Housing: This is the cone shaped metal case that you can see when you peek underneath your car. If you have a front-wheel-drive car it’s stuck on the side of the engine under the hood. If your car is rear-wheel-drive, the transmission will be mounted underneath the car behind the engine.
Gears: Even though you’re not shifting them, an automatic transmission has gears. They are broken into main gears and planetary gears. You need all of these to be able to drive.
Fluid: Transmission fluid is very important to an automatic transmission. All of the magic happens in the fluid. Most cars come with red transmission fluid, good to know if you are looking for a leak.
Filter: All of that fluid has to be clean for your car to shift gears at the right time. To keep things fresh, your transmission has a filter to catch any gunk.”” [READ MORE]

How do you know when your automatic transmission is starting to act up? For one, if your car slips out of gear, or you have difficulty shifting gears, then you probably have transmission problems. Another sign of transmission problems is any discoloration of your transmission fluid, or if your transmission fluid is low. This last one is a big warning sign. Unlike your motor oil which can dissipate, your transmission is supposed to be a sealed system. Your fluid level should remain the same. Any unusual loss of pressure in your transmission system means that you probably have a crack in your casing. When you think you have transmission problems, there’s a very good reason to take it into a shop.
Did you know that a typical automatic transmission can have literally hundreds of parts on the inside? All it takes is one gear getting locked or stuck and you can end up with major transmission problems. The key to avoiding this nightmare is taking your car in for regular transmission service.
