What Causes the Jerking When Shifting from First to Second Gear in an Automatic Transmission?
1 Answers
Automatic transmission jerking when shifting from first to second gear can be attributed to the following reasons and solutions: 1. Reason: Persistent dirt and impurities inside the transmission, especially when they accumulate in the valve body, can cause blockages, preventing effective regulation of oil pressure and leading to jerking, impact, and slippage issues. High temperatures can degrade the quality and frictional properties of automatic transmission fluid, increasing friction and wear, which results in transmission noise. Additionally, sludge (impurities or dirt) can form inside the transmission (e.g., in the valve body), causing jerking and impact. 2. Solution: Remove persistent dirt and impurities from the transmission and effectively control the transmission's operating temperature.
