What Causes CVT Jerking?
2 Answers
Here are the reasons for CVT jerking: 1. Friction Plates: Malfunction of the internal friction plates in the transmission. The transmission mainly refers to the car's gearbox, which is divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, generating speed and torque changes through different gear combinations. Automatic transmissions are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system. CVT can achieve continuously variable transmission over a wide range, obtaining the best match between the drivetrain and engine conditions. By relying on the transmission's continuously variable speed adjustment to adapt to the car's various speeds, the engine can operate under optimal conditions for extended periods, thereby improving combustion efficiency and fuel economy. 2. Fluid: Issues with the transmission fluid. 3. Oil Pump: Malfunction of the oil pump.
When driving a CVT car experiencing jerking, I've summarized several common causes. When the transmission fluid level is low or too dirty, the entire shifting system acts like it's drunk, with uncoordinated movements prone to stuttering. Unstable oil pressure makes it worse, turning the acceleration push into jerky sensations. Wear on the steel belt and pulleys is another issue - my friend's car started having this problem after 100,000 km, feeling like a bicycle chain slipping. Control module failures aren't uncommon either, where the ECU goes haywire sending random commands. Cold starts show this most noticeably, when the transmission can't perform smoothly until fluid warms up. Don't delay - get it checked early.
