Subaru vehicles are renowned for their efficient and reliable performance, making them a popular choice for drivers all over the world. However, there have been concerns about a common issue with Subaru cars equipped with continuously variable transmission (CVT).
In this article, we will explain what a CVT transmission is and how it works, the extent and severity of the CVT issue in Subaru vehicles, possible causes of the issue and how to prevent it, the symptoms of a failing CVT transmission, solutions to fix or prevent the problem, and a comparative analysis of Subaru’s CVT transmission issues with other manufacturers.
What is a CVT Transmission and How Does It Work?
A continuously variable transmission (CVT) is an automatic transmission that can vary seamlessly through a continuous range of effective gear ratios. Unlike traditional automatic transmissions, which have fixed gear ratios, a CVT has a nearly infinite number of gear ratios within its range.
CVTs are designed for smooth and efficient performance since they can always maintain the optimal engine speed for the driving conditions. This feature translates to a higher fuel efficiency of vehicles equipped with CVT.
