Does the Automatic Transmission Filter Need to Be Replaced?
2 Answers
Automatic transmission filters do need to be replaced. The reasons for replacement are: after prolonged use, the transmission accumulates many impurities. If the filter is not replaced regularly, it will affect filtration efficiency, and the transmission fluid quality is prone to deterioration. The replacement interval for automatic transmission filters is approximately every 2 years or 60,000 kilometers. The automatic transmission filter, also known as the transmission filter screen, is installed inside the transmission and serves the following purposes: 1. It filters out oil contaminants and impurities in the transmission; 2. It protects the transmission. The consequences of a clogged automatic transmission filter are: 1. Damage to the transmission solenoid valves; 2. Harsh gear shifts and delayed acceleration shifting.
During my last visit to the 4S shop for maintenance, the technician specifically reminded me that the automatic transmission filter needed replacement. This component functions like the lungs of a transmission, responsible for filtering out metal debris and impurities from the fluid. After checking the manual, I found that most vehicles require replacement every 60,000-80,000 kilometers. A clogged filter is problematic - obstructed oil passages can lead to gear shift jerks, and in severe cases, may even damage the transmission valve body. After the replacement, the entire car felt noticeably smoother, with low-speed jerking completely gone. I recommend all car owners follow the maintenance manual for regular replacements - this is definitely not an area to cut corners, as a major transmission overhaul could cost tens of thousands.
