How much transmission fluid does a Mercury Mariner take?

A drain-and-fill on the Mercury Mariner automatic transmission typically takes 3.5-4.0 quarts. The total system capacity is 7-12 quarts. For a complete fluid exchange, you'll need the full capacity amount.

How often should I change transmission fluid in my Mercury Mariner?

Change your Mercury Mariner automatic transmission fluid every 60,000-100,000 miles under normal conditions. For severe duty (towing, mountain driving, hot climates), change every 30,000-60,000 miles.

Many 2010+ Mercury Mariner models have sealed transmissions with no dipstick. Fluid level is checked via a fill plug underneath the vehicle. Older models typically have a traditional dipstick under the hood.
