Why does the CVT jerk at startup and then become normal?

[OAlexis]

CVT jerking at startup and then becoming normal is due to a dirty transmission filter, which reduces filtration efficiency and allows wear particles to enter the valve body. CVT typically refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between a CVT and a stepped transmission is that its gear ratio is not a series of discrete points but a continuous range of values, thereby achieving good fuel economy, power performance, and driving smoothness, while also reducing emissions. The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also including a power output mechanism. It can be categorized into stepped, continuously variable, and integrated transmissions, with functions such as enabling reverse driving, interrupting power transmission, and changing gear ratios.
