Why does the CVT jerk at start-up and then become normal?

[Roberto]

CVT jerking at start-up is a normal phenomenon for vehicles. Here is more information about CVT transmissions: 1. CVT transmissions are developed with the concept of "stepless speed change and smooth power output," but due to engine braking effects, the vehicle may sometimes feel jerky during start-up or low-speed driving. 2. Sudden release of the accelerator during driving will produce an engine braking effect, causing the vehicle to jerk. This jerkiness is not caused by CVT gear shifting. At medium to high speeds, the vehicle's inertial force is greater than at low speeds, so the impact of engine braking is less noticeable than at low speeds. For better fuel economy, within a certain range of low-speed areas, the impact of engine braking is relatively more noticeable. 3. During low-speed driving, avoid repeatedly pressing and releasing the accelerator abruptly. It is recommended to start smoothly and accelerate or decelerate steadily, which is more conducive to the TCM controlling the CVT to work on the optimal shifting curve, thereby maximizing driving comfort and fuel economy.
