How often should the transmission fluid be changed for an Audi A5?
1 Answers
Audi A5 transmission fluid generally needs to be changed every 60,000 kilometers, or after 4 years. If the car frequently drives on highways, the interval can be appropriately extended by 20,000 kilometers. More information about transmission fluid is as follows: 1. Transmission fluid, commonly referred to as gear oil, is used in the transmission system and serves as a cleaning product for the transmission system. 2. If the transmission fluid is not changed for a long time: it can easily lead to the fluid becoming thicker, reducing oil pressure, which hinders internal cooling and causes the oil temperature to rise excessively. The lubrication effect deteriorates, leading to rapid wear of components and potential damage to internal transmission parts. Below are expanded notes on precautions when changing the transmission fluid for an Audi A5: 1. Specialized equipment for automatic transmissions must be used to completely remove the old ATF fluid and other impurities. Automatic transmission fluid cannot be fully drained using atmospheric pressure alone, as this method only removes about half of the old fluid. Residual fluid can accumulate with sludge and impurities in the valve body, torque converter, and cooling lines, causing blockages in the internal fluid passages. 2. When changing the transmission fluid, it is essential to use the same type of fluid as originally specified for the vehicle. Manual transmission vehicles can only use manual transmission fluid (also called gear oil), while automatic transmission vehicles (including those with manual-automatic transmissions) must use automatic transmission fluid, and the appropriate fluid model must be selected. 3. Currently, the best method for changing transmission fluid is dynamic fluid replacement. This involves using specialized transmission cleaning equipment to thoroughly circulate and drain the old fluid while the transmission is running, before adding new transmission fluid, achieving a fluid replacement rate of over 90%.
