What Causes Jerking During Automatic Transmission Gear Shifts?
1 Answers
Manual shifting difficulties may be caused by clutch issues or transmission malfunctions. If not due to mechanical failure, poor clutch operation techniques can also easily lead to jerking sensations. Clutch Fault Causes and Solutions: Clutch malfunction resulting in insufficient disengagement travel, leading to incomplete clutch separation and gear shifting failure. In this case, it's recommended to visit a repair shop for clutch release timing adjustment; Excessive self-locking force on the clutch side making gear engagement difficult. The solution is to adjust clutch cables and shift stop locks at a repair shop; Deformation of the clutch pressure plate assembly's drive disc causing poor separation. Replacement with a high-quality pressure plate matching the original specifications is advised. Transmission Fault Causes and Solutions: Transmission gear oil requires regular replacement. Delayed replacement significantly reduces lubrication effectiveness, greatly increasing shift resistance and causing rough gear changes. Cold shifts often make vehicle gears feel awkward since gear oil viscosity doesn't reach optimal levels at low temperatures, naturally resulting in poor lubrication and jerking sensations during shifts; Sometimes, wear in shift linkage mechanisms causes misalignment between gear lever position and actual transmission gears, making engagement difficult. If gears won't engage when depressing the clutch, immediate repair and adjustment of shift linkage mechanisms is necessary.
