The service manual says the transmission fluid and filter should be changed after the first 5,000 miles. Why is that?
Almost all vehicle manufacturers recommend you change your transmission fluid after a break-in period. This helps remove contaminants from the transmission that may have remained present following the component’s manufacture. Be sure to check your owner’s manual for manufacturers’ recommendations for all maintenance and upkeep of your vehicle. How often should I drain the air tanks on the air brake system? Some people say daily. Some say just every once in a while. Air reservoirs serve as storage tanks for compressed air. They collect water condensed from the air, and small amounts of oil normally enter the reservoir in the form of vapor, because of the heat generated during the compression. After the water and oil condense, they collect near the tank drain valves and should be drained regularly. If the air tanks are not equipped with automatic drain valves, you should drain the tanks daily during vehicle operation. If equipped with automatic drain valves, they should still be drained
