What is the function of automotive transmission fluid?
1 Answers
Automotive transmission fluid serves the following purposes: 1. Reduce friction and wear, control clutch friction and synchronizer performance. 2. Load bearing (low speed high torque, vibration load), heat dissipation, reduce vibration and noise, remove contaminants at gear meshing points - cleaning function. 3. Prevent corrosion, prevent pitting and surface metal stripping, isolate metal surfaces, and prevent direct contact between metal bodies. Due to different transmission designs, they are divided into manual transmissions and automatic transmissions (further divided into CVT, AMT, etc.). Each transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models will have differences in torque, weight, speed, structure, etc. Therefore, the original manufacturer has its own specified dedicated transmission fluid. Generally, an automotive automatic transmission requires changing the automatic transmission fluid (referred to as ATF) every two years or every 40,000 kilometers. However, this also depends on the vehicle model, as different models have different requirements. It is recommended to change it every 40,000 to 80,000 kilometers. For vehicles that frequently drive at high speeds, it is recommended to change the fluid approximately every 40,000 kilometers.
