In general, an automatic transmission (AT) is considered more reliable than a CVT.
Reasons for automatic transmission reliability:
* Proven Technology: Automatic transmissions have been around for decades and have a proven track record of reliability.
* Durable Construction: Automatic transmissions typically have durable mechanical components, such as gears and planetary gears, to ensure long service life.
*Easier Maintenance: Automatic transmissions require less frequent maintenance than CVTs, which can reduce the cost of ownership.
Reasons for less reliability of the variator:
* Relatively new technology: CVTs are relatively new to widespread use and their long-term reliability is not yet fully known.
* Frequent Maintenance: CVTs require more frequent maintenance, such as belt and fluid changes, which can increase the cost of ownership.
*Sensitivity to increased load: CVTs can be sensitive to increased load, such as towing heavy trailers, which can lead to belt or bearing problems.
However, it is important to note that the reliability of both automatic transmissions and CVTs depends on the following factors:
* Driving style
* Planned maintenance
* Component quality
With proper care and maintenance, both automatic and CVT transmissions can last for many years and cover long distances.
