During a 60,000-mile service, one of the key maintenance procedures is to drain and fill the transmission fluid. This service interval is critical as it helps maintain the proper function of the transmission and prolongs its lifespan. Over time, transmission fluid can become contaminated with particles and degrade in its properties, leading to potential transmission issues. By replacing the old fluid with new transmission fluid, you ensure optimal lubrication, cooling, and operation of the transmission system, which is vital for vehicle performance.

The other options are common services but may not be specific to the 60,000-mile maintenance schedule. For instance, while changing engine oil is essential at regular intervals, it is typically performed more frequently than every 60,000 miles. Battery changes usually depend on the battery's health and age rather than a set mileage, and checking tire alignment is a good practice, but it is not a mileage-based service and is often recommended based on handling issues or after tire installation. Therefore, the focus on transmission fluid maintenance is what makes it a standard procedure at the 60,000-mile mark.
