Hi all, i'm driving a Preve CFE, mileage is 18K, but recently i feel that when i release the accelerator pedal at about 40km/h, the car jerks a bit, even can hear the gearbox sound like wo.. wo.... wo.. wo.... before this, it was wooo........ then slows down. what's the problem? do i need to bring the car for clutch reset and adaptation?
