Auto transmissions are finicky things. They work until they do not. Auto transmission repair is a loaded subject, often with lots of questions from customers that often start with one or more of the "five W's." Here are those five W's of transmission repair and their answers. 

What Is a Transmission and What Does It Do?

Most drivers and owners of cars know that a transmission is a major part of any vehicle. However, a large percentage of those drivers do not know much else about the transmission or what it does. The transmission is connected to the steering column and the gear box and shifting mechanisms. When you shift into gear, manually or automatically, parts of the transmission move into alignment to help the car go the direction and speed you want. They release the wheels and steering wheel into your control to move. 

Where Is the Transmission Located?

It is under the engine and under the car itself. If you could see through the car from different angles, you would see the transmission form an angled "L" with the steering column for automatic transmissions or a lower angle with the manual shift in the floor. From there, it forms a large, capital "I" structure underneath the vehicle as the axles connect the transmission and head off toward the four tires. 

Who Can Fix It?

Only a general mechanic with experience repairing transmissions or a transmission mechanic can fix the transmission. There are very different sorts of transmissions in different cars, and each transmission design requires someone with knowledge and skill to fix it. It is not advisable that you attempt to fix the transmission yourself. 

When Should It Be Repaired?

There is a transmission and/or check engine light on your dashboard that will alert you to transmission problems. When it goes on, you need to schedule an appointment with the mechanic to have it fixed right away. There is a very good chance that it is already showing signs of wear or malfunctioning, even if you cannot feel it when you shift or notice that something is wrong. 

Why Have It Fixed as Soon as Possible?

Leaving a transmission to slowly wear out and slip is very dangerous. You are not only putting your own life in danger but also the lives of everyone in the car with you and the lives of everyone else on the road. If your transmission suddenly goes, you will lose control of the car, and it will be difficult to switch into any other gear or operate the car properly.
