What Happens If Automatic Transmission Fluid Is Not Changed for a Long Time?
1 Answers
Due to the specific operating environment inside the transmission, transmission fluid has a certain shelf life. If not changed for a long time, the performance of the fluid will deteriorate, generating more impurities, which can lead to accelerated wear of transmission components, earlier occurrence of failures, or higher failure rates. Below are the relevant details: 1. Function of Transmission Fluid: The main role of transmission fluid is to keep the shifting system clean and to lubricate the transmission components, thereby extending their lifespan. 2. Replacement Interval: Generally, automatic transmission fluid (ATF) should be replaced every two years or every 40,000 kilometers. Manual transmission fluid can usually be replaced at 60,000 kilometers, but this depends on the vehicle model. Vehicles that frequently drive at high speeds are advised to undergo maintenance earlier at a repair shop.
