CVT Transmission Pros and Cons

Wondering about CVT transmission pros and cons? Is your car equipped with a CVT transmission? Here’s some information on pros and cons of CVT transmission.

Have you ever driven a car that is equipped with a CVT transmission? If you are an automotive enthusiast, I am sure you might already be aware of this technology. In case you don’t know a lot about CVTs, let me tell you what it is and how it works. A CVT, or continuously variable transmission is a type of automatic transmission that has the ability to provide an unlimited range of gear ratios in automobiles. CVTs were earlier used in industrial applications, but recently car manufactures like General Motors, Nissan, Audi, Ford and Honda have started using CVT technology in their cars. CVTs use very few components and have a simplistic design. With their ability to provide unlimited gear ratios, they surely have some advantages over the conventional transmissions. If you are planning to buy a car equipped with a CVT, it would be a good idea to find out more about CVT transmission pros and cons. Here’s some information on the CVT mechanism and CVT transmission pros and cons.

CVT Transmission: How it Works

To understand CVT transmission pros and cons, you must first understand its mechanism. A CVT uses a pulley and belt system to provide an unlimited range of gear ratios. It is different from the automatic transmission which has a set number of gear ratios. A CVT uses components such as a high density rubber/metal belt, a driving pulley actuated by a hydraulic cylinder, a mechanical torque-sensing driving pulley, sensors and microprocessors to perform its function. The transmission has the ability to change continuously by using an infinite number of gear ratios between maximum and minimum values. To facilitate different gear ratios, variation has to be made in the working diameters of the two main pulleys in the transmission. The pulley connected to the engine is called the input pulley and the output pulley is the one that is connected to the drive wheels. One side of the pulley is fixed while the other side is movable. This movement is facilitated by a hydraulic cylinder which can change the space between the two sides of the pulley. When the pulley halves come closer to each other, the belt that runs between them goes higher on the pulley, which in turn increases the diameter of the pulley. Thus, the ratio is continuously being changed unlike the traditional transmission where the ratio is changed in stages by shifting gears.

CVT Transmission: Advantages and Disadvantages Now that you know how CVTs work, it’s time to find out about CVT transmission pros and cons. As far as advantages are concerned, CVTs provide an unlimited gear ratios and improved performance. The infinite ratios help in maintaining a steady cruising speed. It also cuts down the fuel emissions and thus improves fuel economy. Due to its ability to make changes in the ratio continuously without any steps in between, a CVT can work to keep the engine in its optimum power range, thereby, increasing gas mileage and fuel efficiency. CVT also provides quicker acceleration than a conventional automatic. Well, these were the advantages, now it’s time to find out more about CVT transmission problems. One of the major drawbacks is that it might not be able to provide a driving feel that a conventional automatic transmission may provide. The cars equipped with CVT make an irritating noise especially when you try to accelerate. This noise can be compared to that of a slipping clutch. Some users have also complained of a lack of power that can be attributed to the lower torque capacity with CVTs. If you are driving a car equipped with a CVT, you might take some time to adjust to the dynamics. Another transmission problem associated with CVT is the inability to check the fluid level on your own. You need to get it checked by the dealer and the fluid is a little expensive as well. Though automatic transmission has its own set of car transmission problems

, but most car owners are accustomed to the driving dynamics of an automatic transmission. Since adjusting to a CVT might take some time, the car manufacturers are trying to incorporate features in order to provide the driving feel a refined torque converter automatic provides.

So, this was some information on CVT transmission pros and cons. Though many car owners are aware of the automatic transmission problems, but they are used to the driving feel and dynamics of an automatic transmission. If you are planning to buy a car equipped with a CVT, make sure that you go for a thorough test drive. Hope you found the information on pros and cons of CVT transmission useful.
