What transmission fluid does Chevy recommend?
The short answer: for most current Chevrolet models with automatic transmissions, Dexron VI automatic transmission fluid (ATF) is recommended. Always verify the exact specification for your vehicle’s year, model, and transmission code in the owner's manual or GM service data.
Chevrolet’s guidance on transmission fluid varies by model, year and transmission type. In broad terms, modern GM automatics rely on Dexron VI ATF, while older vehicles may require earlier Dexron formulations. The rules for manual transmissions differ and should be taken from the specific owner's manual. This article explains the official stance and where to confirm the right fluid for your Chevy.
Chevrolet's Guidance by Transmission Type
Automatic transmissions
Most modern Chevrolets equipped with automatic transmissions specify Dexron VI ATF as the standard fluid. In some service bulletins, Dexron VI‑H is referenced for certain high‑heat or performance-oriented units. If your vehicle originally called for Dexron II or Dexron III, Dexron VI ATF is commonly acceptable under GM guidance, but you should verify the exact specification for your model year and transmission code in the owner's manual or GM service information before purchasing.
Manual transmissions
Manual transmissions in Chevrolet vehicles require a different type of fluid than automatics. The exact specification is listed in the owner's manual and can vary by model and year. In many cases, GM manuals call for a GM-approved manual transmission fluid or a GL‑4 gear oil; always confirm the precise requirement for your specific car before buying or topping up.
How to Confirm the Right Fluid for Your Chevy
To ensure you’re using the correct transmission fluid, start with the owner’s manual. If you don’t have it handy, you can view the manual online via Chevrolet’s official site or GM’s service information portal. Look for sections labeled “Lubricant Specifications,” “ATF,” or “Transmission Fluid” to note the exact specification (for example, Dexron VI or another GM‑specific designation). If you’re unsure, contact a Chevrolet dealer or a qualified technician with your VIN or transmission code to confirm the right fluid.
Maintenance and Service Tips
When servicing a transmission, use the recommended fluid grade and avoid mixing fluids of different specifications. Replace any transmission filter where the design calls for it, and follow the service interval in the owner's manual. If you notice a leak, burning smell, or unusual shifting after a fluid change, have the transmission inspected promptly to prevent damage.
Summary
Overall, Dexron VI ATF is the prevailing recommendation for most current Chevrolet automatics, with Dexron VI‑H appearing in some service notes for specific units. Always confirm the exact fluid requirement for your vehicle by checking the owner’s manual or GM’s official service information, and consult a dealer or certified technician if you’re uncertain. For manual transmissions, adhere to the manual’s specification, which often calls for a GM‑approved GL‑4 gear oil or an equivalent fluid.
