A transmission fluid change, often referred to as a “flush,” involves draining the old automatic transmission fluid and replacing it with new fluid. This process may also include cleaning the transmission pan and replacing the filter. A simple drain and refill typically replaces only a portion of the fluid, while a complete fluid exchange utilizes a machine to pump out and replace nearly all of the fluid in the system. This service is crucial for maintaining the health and longevity of an automatic transmission.
Regular transmission maintenance contributes significantly to vehicle performance and lifespan. Fresh fluid ensures proper lubrication and cooling of internal components, preventing premature wear, overheating, and costly repairs. Historically, transmission fluid changes were less frequent. However, with the increasing complexity of modern transmissions, more regular service intervals are recommended by manufacturers. Neglecting this maintenance can lead to reduced fuel efficiency, shifting problems, and ultimately, complete transmission failure.
