Myths and truths about the unreliability of the variator

Today, modern cars are increasingly equipped with continuously variable transmissions, which, according to the idea of the engineers, should provide the best possible realization of the power characteristics of engines and at the same time save fuel. At the same time there is no consensus among the car owners about the reliability of such transmissions. Some are of the opinion that they are not too reliable, while other car owners assure that with proper maintenance such a variator will last for many years. Let’s talk more about the reliability of variators. If this system, and with it others, are damaged due to an accident or other reasons, then do not waste time repairing your car. It is not profitable. It is better to give it for recycling:

Myths and Truths about Variator Unreliability

Types of continuously variable transmissions

V-belt variators are the most common, which are characterized by the simplicity of design, they do not require maintenance and can last for many years. Variators are made with a pushing belt or a pulling chain. The latter is considered a more reliable design, but replacing the consumables of such a gearbox will cost the car owner a solid amount of money. All such transmissions are fully controlled by automation, the electronic control unit monitors the load on the variator, preventing its breakdowns.

Myths and Truths about the Unreliability of Variators

The benefits of using variators

One of the benefits of using these continuously variable transmissions is the absence of jerking when shifting gears. Therefore, acceleration here is much smoother than with manual or automatic transmissions. The car starts off as smoothly as possible, which eliminates the likelihood of the engine stalling at the beginning of the drive.

Variators are characterized by silent operation, which is achieved through their special design and the use of appropriate oil. Such gearboxes are ideal for the city, where you need to constantly lower and raise the steps. If the mechanics and automatic will constantly change the steps, thereby increasing the load on the entire transmission, the variator smoothly transmits power, significantly reducing the load on all nodes of the machine.

Advantages and disadvantages of variators: myths and reality

Disadvantages of variators

The disadvantages of variators usually include their mediocre reliability, in particular, these transmissions at high mileage begin to erase cones, and this is the most expensive element in the transmission. Approximately at 200 thousand runs, it is necessary to overhaul the variator, replacing not only the belt, but also the worn out cones.

The car owner should also remember about the obligatory qualified servicing of the variator, in which the transmission oil is changed more often in comparison with automatic transmissions. Such service on a variator is performed almost every 30-40 thousand kilometers, which significantly increases the car’s maintenance costs.

Advantages and disadvantages of variators: myths and reality

With a variator it is not allowed to tow other cars or even small trailers. In such a case, the load on the transmission increases significantly, which quickly overheats and fails. It should be taken into account that the device of the variator is quite fragile, because of the increased loads and continuous use of such a gearbox quickly fails.

All parts of such gearbox are interconnected, the breakdown of one node will invariably lead to the failure of other systems of transmission, and, eventually, if the car owner does not apply in time to repair, it is already required to perform a complete overhaul of the variator.

Another peculiarity of such transmissions is their rapid failure while driving at high speed. If you are looking for a car in order to constantly move at high speed on the autobahns, the gearbox variator is clearly not the best choice.

To summarize

Variators are a popular type of gearbox today, which use a unique development of the genius Leonardo da Vinci, invented by him 500 years ago. Such transmissions have their certain advantages and disadvantages, which should be considered when choosing a car. Such transmission will require more attention from the car owner, it does not like increased loads, the car will need to change transmission oil more often and timely perform all scheduled repairs.
