A continuously variable transmission (CVT) does indeed differ in several key aspects from traditional step-gear transmissions. Here are the true characteristics based on your statements:
-
Is the same as a step-gear transmission: False. A CVT operates differently than a step-gear transmission, as it provides an infinite number of gear ratios within a given range, allowing for smooth acceleration without distinct gear shifts.
-
Can use the same fluid as any other automatic transmission: False. CVTs usually require a specific type of transmission fluid that is formulated for their unique design and operational requirements. Using regular automatic transmission fluid (ATF) can lead to poor performance or even damage.
-
Requires a transmission fluid specially formulated for CVT needs: True. CVTs need a specially formulated fluid (often labeled as CVT fluid) that is designed to handle the unique stresses and characteristics of a continuously variable system.
-
Needs transmission fluid exchanges much more frequently: False, in general, compared to traditional automatic transmissions. The frequency of fluid changes for CVTs can vary based on manufacturer recommendations, driving conditions, and vehicle use, but often, they may have longer service intervals. However, it is important to follow the manufacturer’s guidelines for maintenance.
In summary, the statement regarding requiring a specially formulated fluid is true, while the others are false.
