What Happens If You Don't Change Automatic Transmission Fluid?
1 Answers
Not changing automatic transmission fluid will cause severe gear wear inside the transmission, resulting in increased noise during driving, rough gear shifting with noticeable jerking, and in severe cases, it can directly lead to shortened transmission lifespan or complete failure. When replacing transmission fluid, be careful not to use inferior quality products as they have poor temperature resistance and are prone to oxidation, which can generate sludge and deposits. This will damage friction materials, sealing rubbers, and metal components, leading to abnormal transmission operation. Automatic transmission fluid is specifically designed for automatic transmissions. Early automatic transmissions didn't have dedicated fluid and used engine oil instead. Due to significant differences in working conditions and technical requirements, the practice of using engine oil as automatic transmission fluid was quickly phased out.
