We at Jim Hardman Buick GMC, Inc. know how important your car's transmission system is. Without one, the car's engine wouldn't deliver much power. Even though many designs exist, most transmissions operate on the same basic principles. As a car's speed increases, its transmission helps control torque and power output.
If you're driving in Gainesville, GA, chances are you're using an automatic. They're the most common transmissions in cars today. Most of the time, they've used a hydraulic system to control it. Instead of having a clutch, automatic transmissions usually have a torque converter. But, some of them use fluid flywheels, too.
Of course, manual transmissions are still popular. They're not reliant on a computer system, so you have more control over them. The most common manual transmissions use constant-mesh gearboxes now. To make them, they use diagonal-cut helical gears and a dog clutch. Typically, manuals are less expensive than an equivalent automatic. Plus, they're easier to maintain if you have to work on them.
