What it does:
Cleans the fluid: ATP transmission filters are designed to keep transmission fluid — the life blood of your transmission — clean as debris accumulates from normal wear.
Protects vital parts: Clean fluid helps keep the valve body and other critical components from becoming clogged and inoperable.
Supports service life: Regularly replacing the filter helps extend transmission life and reduce the possibility of costly repairs.
Change the filter as part of your routine transmission service using the correct fluid and gasket/seal for your vehicle per the service procedure.
It filters your automatic transmission fluid to keep it clean, helping prevent debris from clogging the valve body and other vital components as the transmission wears.
