What is the reason for the abnormal noise when starting and shifting gears in the Mistra 1.6t?

[LeJohn]

Mistra 1.6t produces abnormal noise when starting and shifting gears, which may be due to transmission issues. Below are the specific reasons: Blockage inside the valve body: In many cases, it is not the internal valve body that is damaged, but rather the presence of stubborn dirt and impurities inside, especially when these accumulate in the valve body, forming blockages. This prevents effective regulation of oil pressure, leading to issues such as jerking, impact, and slipping. Transmission overheating: At the same time, the issue of transmission overheating cannot be ignored. According to data from the Automatic Transmission Repair Association: "Over 90% of faulty automatic transmissions are caused by overheating." Solution: Therefore, to completely resolve transmission issues and prevent their recurrence, it is essential to remove stubborn dirt and impurities from the transmission and effectively control the transmission's operating temperature. This is also the key to solving transmission faults without disassembly and repair.
