What are the causes of gear shift jerking in a 6AT transmission?
1 Answers
6AT transmission gear shift jerking may be caused by internal contamination and high temperature. Here are the specific details: 1. Transmission contamination: When a transmission exhibits gear hunting, jerking, impact, slipping, or abnormal noises, in many cases it's not due to internal valve body damage, but rather the presence of stubborn dirt and contaminants inside. Especially when these contaminants accumulate in the valve body, forming blockages that prevent effective regulation of oil pressure, leading to jerking, impact, and slipping issues. 2. Transmission overheating: High temperatures can degrade the quality and frictional properties of transmission fluid, increasing friction and wear. This results in transmission noise, while sludge also forms inside the transmission, causing jerking and impact during gear shifts.
