What to Do When Experiencing Severe Jerking During 2nd to 3rd Gear Shift in Automatic Transmission?

[DeStella]

Severe jerking during gear shifts in an automatic transmission can be caused by several factors, such as a stuck solenoid valve inside the transmission, dirty transmission fluid, pressure loss in the oil pump, or even clutch slippage within the transmission. Jerking, or noticeable shift shock, primarily occurs when there is a mismatch between the engine speed and the driveshaft speed. Below is an introduction to automatic transmissions: 1. Overview: An automatic transmission, as the name suggests, eliminates the need for manual gear shifting by the driver. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, an automatic transmission has six gear positions, arranged from top to bottom as: P (Park), R (Reverse), N (Neutral), D (Drive), S (Sport), and L (Low). 2. Types: Common types of automatic transmissions in vehicles include hydraulic automatic transmissions, hydrostatic transmissions, electric transmissions, stepped mechanical automatic transmissions, and continuously variable transmissions (CVTs).
