Does the Passat B5 automatic transmission have shifting shock when warmed up?
1 Answers
Passat B5 automatic transmission has a shock when shifting to D gear after warming up. Valve body blockage: When the transmission experiences jerking, hesitation, shock, slipping, or abnormal noises, in many cases, it is not due to damage to the internal valve body but rather the presence of stubborn dirt and impurities inside. Especially when dirt and impurities accumulate inside the valve body, forming blockages, it becomes impossible to effectively regulate the oil pressure, leading to issues like hesitation, shock, and slipping. To resolve this, the valve body is removed and tested on an oil circuit test bench. Based on the test report, the worn plungers are identified, and the valve body is repaired using imported American equipment. The plungers are replaced and upgraded, and the pressure is recalibrated, which can eliminate the fault. This process typically takes about 5-8 hours. 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.
