Mazda 6 Transmission Fluid

The Mazda 6 transmission fluid type depends on your transmission — automatic models require the manufacturer-specified automatic transmission fluid. Manual transmissions use manufacturer-specified manual transmission fluid. See the year breakdown below.

Fluid type and capacity can change by engine, drivetrain, and transmission. Verify the exact branch before filling anything.

Frequently Asked Questions

What transmission fluid does a Mazda 6 use?
The Mazda 6 transmission fluid type depends on the year and transmission. Automatic transmissions require the manufacturer-recommended ATF — using the wrong type can cause shifting problems or damage. Manual transmissions use manufacturer-specified manual transmission fluid. See below for your specific year.
How much transmission fluid does a Mazda 6 take?
A drain-and-fill on the Mazda 6 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 Mazda 6?
Change your Mazda 6 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.
Does the Mazda 6 have a transmission dipstick?
Many 2010+ Mazda 6 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.
