What kind of ATF does Chevy use?
Chevrolet vehicles typically require Dexron automatic transmission fluid, but the exact specification depends on the model year and transmission type. Here’s what you need to know to choose the right fluid.
Chevrolet ATF standards by era and transmission
In modern Chevrolets, GM generally specifies Dexron VI as the multi-vehicle transmission fluid for most transmissions built since the early 2010s. Older Chevrolets may specify Dexron II or Dexron III. The only reliable way to be sure is to check your owner's manual, the transmission dipstick, or a GM service bulletin for your exact model and transmission combination.
Below is a concise guide to the most common specifications you might encounter on Chevrolet vehicles today. This list helps you identify which ATF to buy when servicing a transmission.
- Dexron VI (GM Dexron VI Multi-Vehicle ATF) — The standard recommendation for most modern GM automatics, including many Chevrolet transmissions since roughly 2010. It is designed to be backward compatible with Dexron II/III where GM specifies compatibility.
- Dexron II/III — Used in many older Chevrolet transmissions (1990s to early 2000s). If your manual or a label calls for Dexron II/III, Dexron VI can often be used as a replacement, but verify with GM specs for your model.
- Other GM-specific fluids — Some very old or specialty GM units may list alternate fluids in service bulletins; these cases are uncommon on everyday Chevys produced in recent years. Always verify with the official specification for your vehicle.
In short, for most Chevys manufactured in the last decade, Dexron VI is the recommended fluid. Older models may require Dexron II/III. When in doubt, verify with your manual or contact a dealer.
How to confirm the exact specification for your Chevy
Use these steps to confirm the exact ATF specification for your vehicle before purchasing fluid or starting a change.
- Consult the owner's manual for the exact ATF specification and capacity for your transmission.
- Check the transmission dipstick or a label on the transmission case for the specification (often printed on the dipstick or stamped on the case).
- If you still aren’t sure, contact a Chevrolet dealer or GM Customer Service and provide your VIN to get the precise specification for your vehicle.
Following these steps ensures you use the correct ATF and maintain your transmission’s performance and reliability.
What to do if you are changing ATF yourself
If you’re servicing your transmission fluid yourself, obtain the correct ATF specification, follow safe draining and refilling procedures, and check the fluid level after the engine is warmed up and the transmission is in Park. Use the GM-approved Dexron VI fluid if specified for your model, and avoid mixing fluids unless GM instructions allow it.
Summary
Chevrolet’s ATF requirements vary by model and transmission, but Dexron VI is the dominant specification for most modern GM automatics. Older Chevys may require Dexron II/III. Always verify with your manual or a dealer to ensure you use the correct fluid, and consider sticking with GM-approved Dexron VI multi-vehicle ATF for broad compatibility.
