Automatic transmission fluid (ATF) for the 2003 Matrix
The automatic transmission in the 2003 Matrix is designed to use ATF that meets or exceeds the Dexron II or Dexron III specification. This ensures proper shifting performance and longevity. The exact label on the bottle may read Dexron II/III-compatible ATF, which is suitable for use in this model.

Using the recommended ATF helps maintain smooth shifts and proper hydraulic operation. If you cannot locate Dexron II/III-grade ATF, a knowledgeable technician can confirm acceptable cross-compatibility with Dexron II/III specifications for your vehicle’s transmission.
Manual transmission fluid for the 2003 Matrix
The 5-speed manual transmission requires a gear oil rather than ATF. Use a 75W-90 GL-4 gear oil. Do not use GL-5 gear oil, as it can affect the synchronization and shift quality.
