Mazda B-Series Transmission Fluid

Frequently Asked Questions

What transmission fluid does a Mazda B-Series use?

The Mazda B-Series 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 B-Series take?

A drain-and-fill on the Mazda B-Series 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 B-Series?

Change your Mazda B-Series 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 B-Series have a transmission dipstick?

Many 2010+ Mazda B-Series 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.
