What causes gear shifting jerks in Haval H2 automatic transmission?
2 Answers
Damaged solenoid valves are a major cause of jerking during gear shifts. The sensation of jerking is akin to being kicked from behind, and it can be categorized as either occasional or occurring at fixed intervals. Reasons for gear shifting jerks: Gear shifting jerks occur when the engine speed does not match the vehicle speed at the moment of clutch release, meaning there is a speed difference between the engine and the clutch plate. In most cases, the engine speed is lower than the clutch plate speed. Shifting recommendations: To effectively prevent jerking, after shifting into a new gear, when lifting the clutch to the semi-engagement point, ensure the engine speed matches or is slightly higher than the clutch plate speed.
Well, I've been driving for many years, and gear shift jerks in automatic transmissions are quite common, not just with the Haval H2. Most of the time, it's due to transmission fluid issues. If the oil is too old or insufficient, the car won't shift smoothly, and it can make the clutch sluggish. Additionally, electronic control systems like the gear shift control computer are prone to faults, possibly because sensors are dirty or aged, leading to inaccurate speed data readings. Aggressive acceleration while driving can also trigger jerks, especially in stop-and-go city traffic where the transmission can't keep up. I recommend checking the fluid first and replacing it if necessary, then have a mechanic connect a diagnostic tool to check for error codes. Fixing minor issues early saves money and ensures safety. Regular maintenance is key—don't let small problems turn into big ones.
