ATP's Transmission filters are designed to keep the life blood of your transmission (transmission fluid) clean. Every transmission will eventually accumulate debris from normal wear and tear. It is critical that the transmission fluid is kept clean so the valve body and other vital components do not become clogged making them in-operable. By regularly replacing your transmission filter, you will be extending your transmission's life and reducing the possibility of costly repairs that could have been avoided.
