What Causes the Jerking When Shifting from 2nd to 3rd Gear in a 6AT Transmission?

[MaddoxDella]

6at transmission 2nd to 3rd gear jerking reasons include stubborn dirt and impurities inside the transmission and solenoid valve damage. Dirt and impurities in the transmission: Automatic transmission jerking often occurs not due to internal valve body damage, but because of stubborn dirt and impurities inside, especially when these accumulate in the valve body, forming blockages that prevent effective regulation of oil pressure, leading to jerking, impact, and slippage. Remove stubborn dirt and impurities from the transmission. High temperature: High temperatures can degrade the quality and frictional properties of automatic transmission fluid, increasing friction and wear, which leads to transmission noise. At the same time, sludge, impurities, or dirt can form inside the transmission, causing jerking and impact. If the temperature exceeds 120 degrees Celsius, rubber sealing materials begin to harden, eventually leading to leaks and reduced hydraulic pressure. If the temperature rises further, the transmission may start to slip, and slipping in turn causes the temperature to rise even higher. If not addressed promptly, the transmission may fail completely.
