Toyota recommends that the eCVT transmission fluid lasts the life of the vehicle, but many mechanics suggest a change every 60,000–100,000 km to ensure longevity.

Type of Fluid: The recommended fluid is Toyota WS World Standard ATF, which helps maintain the smooth operation of the eCVT.
Why Change Fluid?: While the fluid may last a long time, replacing it periodically can prevent wear on the internal components and reduce the risk of overheating.
