Every automatic transmission accumulates debris from normal wear and tear over time. Keeping transmission fluid clean is critical to preventing the valve body and other vital internal components from clogging and becoming inoperable. Regular replacement of the transmission filter extends transmission life and helps avoid costly repairs down the road.
