What is the reason for the severe jerking in the Lavida automatic transmission?

[BrantleyLee]

Damaged solenoid valves are a major cause of jerking. The sensation of jerking is like being kicked in the backside, and it can be categorized as either sporadic or occurring at fixed intervals. The distinction is simple: sporadic jerking occurs without any predictable pattern, while fixed jerking happens at a certain RPM or when shifting between specific gears (e.g., from 2nd to 3rd gear), or at a fixed speed. Here is an introduction to the Lavida: 1. Exterior Design: It adopts Volkswagen's latest family design language, featuring a U-shaped front grille that gives it a more upscale look compared to the previous generation. High-end models also come equipped with LED headlights. 2. Interior Design: The Lavida's dashboard is equipped with a large touchscreen supporting features like built-in navigation, CarPlay, and CarLife. The interior craftsmanship and materials are also quite good, with extensive use of piano black lacquer trim for an elegant look. High-end models further include keyless start, adaptive cruise control, front and rear parking sensors, and a rearview camera.
