How Does a Hydraulic Transmission System Work?

Learn How to Avoid a Rather Expensive Transmission Repair

There are several types of automatic transmission systems; however, the hydraulic ones are the most popular. Most vehicles on the road today use a hydraulic gearbox. As we all know, transmission repair services are not particularly cheap. As a matter of fact, a complex repair may set you back of a considerable amount of money. So, making sure that your gearbox won’t fail is a main part of any auto maintenance plan. But, in order to be able to keep your car’s transmission in good condition, you first need to understand how it works.

The hydraulic fluid provides the power
Unlike a manual transmission, where all operations and functions are performed by mechanical means, an automatic transmission uses fluid to shift gears and maintain gear selection. Basically, all the mechanical components are replaced with a special type of fluid which provides the necessary power to change gears when pressure is applied.

The torque converter adds the pressure
Each hydraulic transmission is equipped with a special pump called a torque converter. This pump provides the necessary pressure so that the fluid can engage and facilitate the many facets of automatic transmission operations. Without a functional torque converter, an automatic gearbox would be useless. A torque converter is comprised of a rotor, a special pump, and a series of fan blades that rotate and spin in order to create pressure. Since the torque converter is subjected to very high stresses, it often malfunctions. In other words, if there is something wrong with your car’s transmission, it may be from your torque converter.

All transmission functions rely on the ability of the torque converter to provide pressure
The structure of a hydraulic transmission system is relatively simple. As long as the fluid is replaced regularly and the converter is in good condition, then you should not have any problems with the gearbox. However, even when you do have a problem, it is important to bring your car to a transmission repair specialist.
