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.

The Different Types of Gearbox Systems

How to Choose a Gearbox That Won’t Require Much Transmission Repair in the Future

Choosing a gearbox for a vehicle used to be simple, you could either go with a manual or an automatic gearbox. However, things have changed dramatically for the last couple of decades in the automotive industry. Now, you have to choose between traditional automatic, dual-clutch automatic, semi-automatic, manual, continuous variable, etc. Obviously, choosing a gearbox for your car is more complicated now than ever. As a transmission repair specialist, I’ve had the chance to work on most major types of gearboxes. Here’s what I’ve concluded.

Traditional automatic

This type of gearboxes are still available in many new models. For instance, Land Rovers, Jaguars, and BMWs are some of the most common examples of cars that use eight- or nine-speed automatic gearboxes. The main advantage of traditional automatic systems is reliability. They have been around for almost 50 years, and have proven to be resistant to wear and tear. On the downside, they are quite slow. Additionally, they make the cars less fuel efficient.

Dual-clutch automatic

Just as the name entails, dual-clutch gearboxes have two clutches. However, don’t imagine that you’ll have two pedals in the car. These clutches are operated electronically and controlled by computers. One clutch controls even-numbered gears, while the other controls the odd-numbered gears. The result is a very fast gear shifting. Another great benefit is that these gearboxes make for a lower fuel consumption. However, they also come with several disadvantages. First of all, they have been around for only ten years, which means their long-term reliability is not proven yet. Another problem is that they are quite slow at start, when the clutches select the first gear.

Continuously variable transmission (CVT)

These gearboxes come with an innovative design and functionality. They do not have cogs, like most gearboxes, Instead, they use some sort of cones and a special belt. One con is connected to the wheels, the other to the engine, and the belt wraps both cones together. As the cones move toward or away from each other, the angle of the belt changes, thus altering the gearing. Although this is a revolutionary design, it still requires more work as many of these systems have experienced various problems. It’s also important to mention that the transmission repair services for these gearboxes are very expensive.

Signs of Transmission Problems

How to Determine If You Need a Professional Transmission Repair Service

If you own a car with automatic transmission, then you should ensure regular maintenance in order to avoid costly repairs. The transmission system is one of the most complex mechanisms installed on your vehicle. Although the system is designed to be resistant and efficient, there are cases when it may develop problems. It is crucial for you to be able to determine when your transmission has problems so that you can avoid an expensive transmission repair service. Here are some of the most common signs of transmission failure.

Leaks
The transmission system is enclosed in a sealed unit so it should not leak. However, due to wear and tear, excessive use, or damage, the transmission unit may lose liquid. You must know that your gearbox will not run more than a few miles if it doesn’t have enough liquid. So, make sure you check underneath your vehicle every time you pull out of your garage, driveway, or a parking lot. If you see any leaks, make sure you determine the source of the problem.

Delayed Engagement
One very common indicator of transmission failure is when the car doesn’t engage into drive immediately after you shift from “P” into “D”. Additionally, you may also notice that the car revs the engine as you give it gas but the vehicle isn’t moving forward as it should.

Slippage
If your car is shifting gears for no apparent reason, then you may need to visit a professional transmission repair service provider. Sometimes, the noise from the engine may change in pitch or start to sound like whining. This is another indicator that your transmission system needs professional assistance.

Rough Shifts
If your car refuses to shift gears when it should or the shift is accompanied by a loud clunk, then your transmission system needs to be repaired. Luckily, there are many reputable auto repair shops that offer transmission repair services.
