What kind of transmission fluid does a Chevy take?

Most Chevrolet automatic transmissions built since around 2006 use Dexron VI automatic transmission fluid. Some older Chevys may require Dexron II or Dexron III, or other GM-specific specifications, so always verify the exact specification for your model in the owner’s manual or on the transmission label.

This article explains how to identify the correct fluid for Chevrolet vehicles, the common types you’ll encounter, and practical steps to confirm the right specification for your car.

Understanding GM transmission fluid specifications

GM specifies automatic transmission fluids by generation and transmission family. The most common modern requirement is Dexron VI, introduced to supersede older Dexron II/III fluids. While Dexron VI is generally backward-compatible with many Dexron II/III transmissions, compatibility can vary by model and year, so the owner's manual or GM service documentation should be consulted for your exact vehicle.

Common transmission fluid types used in Chevrolets

Here are the fluid types you’re likely to encounter, along with the era or transmissions they pertain to. Use this as a quick reference, but rely on the official specification for your car.

Dexron VI (including Dexron VI-H variants): This is the current standard for most GM automatics from the mid-2000s to today. It is generally backward-compatible with older Dexron II/III transmissions, but confirm for your specific model.

Dexron II or Dexron III: Older GM automatic transmissions (typically pre-2006) may specify Dexron II or Dexron III. Some service updates allow Dexron VI as an upgrade, but your manual or label will confirm.

Other GM-specific Dexron-family fluids: Some models may reference a GM specification label or variant; again, the exact text on the cap or dipstick is the authority.

In practice, Dexron VI covers the majority of current Chevrolets, while older models may rely on Dexron II/III. Always verify to avoid shifting issues or transmission damage.

How to verify the exact fluid requirement for your vehicle

To avoid missteps, follow these steps to confirm the correct transmission fluid specification for your Chevy:

Check the owner's manual for the official ATF specification listed in the Transmission Fluid section.

Inspect the transmission fill cap or pan label, which often lists the required ATF type (e.g., Dexron VI or Dexron II/III).

If you can’t find the manual, use the vehicle identification number (VIN) to look up the specification on GM's service information site or contact a Chevrolet dealer.

When in doubt, use Dexron VI as a default if your manual does not specify a different Dexron family, but avoid using non-GM fluids if the spec calls for a GM Dexron variant.

Accurate identification of the correct ATF helps maintain smooth shifting and transmission longevity; when unsure, consult a certified technician.

Summary

In short, Dexron VI is the prevailing recommendation for most modern Chevys, with older models potentially requiring Dexron II/III. Always rely on the vehicle’s manual, the fill cap label, or GM's official service information to confirm the exact transmission fluid specification for your model and year.

What is the difference between ATF and Dexron?

Dexron is a specific brand name for a type of Automatic Transmission Fluid (ATF) developed by General Motors. ATF is the general category for all fluids that perform this function, and "Dexron" is just one of the many specifications that an ATF can meet. Many modern ATFs are formulated to be "multi-vehicle" fluids that meet Dexron specifications (among others) and are often labeled as Dexron-compliant or an equivalent.

ATF (Automatic Transmission Fluid)

What it is: A hydraulic fluid used in automatic transmissions.
What it does: Lubricates and cools the transmission, cleans metal surfaces, and helps clutch plates transfer power.
Composition: A base oil with a package of additives, including friction modifiers, which are critical for proper shifting.
General category: "ATF" is the overarching term for all fluids that perform this function, regardless of the brand or specification.

Dexron

What it is: A trademark and a set of specifications for automatic transmission fluid created by General Motors.
What it does: The fluids that meet Dexron specifications have a specific performance profile designed to work with GM transmissions.
Specific versions: There have been many versions, such as Dexron II, Dexron III, and the most current Dexron VI, each with improved properties like viscosity control and oxidation inhibitors.
Usage:
- Dexron VI: The current standard for most modern GM vehicles, and it is backward-compatible with earlier Dexron specifications.
- Dexron III: Often specified for GM vehicles made before 2005, but modern multi-vehicle fluids are often a good replacement.
Important note: When buying, you're looking for an "ATF" that meets the required "Dexron" specification, not necessarily a product labeled "Dexron" specifically.

In summary

ATF: is the general type of fluid.
Dexron: is a specific brand and specification for that fluid.
Most modern automatic transmissions require a fluid that meets a specific Dexron specification (like Dexron VI) and often a multi-vehicle ATF that meets other specifications as well (like Mercon LV or ATF+4). Always check your owner's manual to ensure you are using the correct fluid for your vehicle.

What replaced Dexron III?

Equivalent fluids for Dexron 3 include multi-purpose fluids labeled with terms like "Dex/Merc" or "Dexron III/Mercon", and specific products from major brands like Chevron MD-3, Castrol ATF TQ-DIII, and Mobil ATF 320. While modern Dexron VI is a successor, it is generally not recommended as a direct substitute in older vehicles that originally specified Dexron 3.
Specific equivalent fluids

Chevron Automatic Transmission Fluid MD-3: This is explicitly designed as a replacement for Dexron III and Mercon.
Castrol ATF TQ-DIII: A multi-purpose fluid that meets the requirements.
Mobil ATF 320: Another option listed as a cross-reference for Dexron III.
Shell Donax TX: An equivalent fluid for many applications.
BP Autran Dexron-III/Mercon ATF: A specific product that serves as a direct equivalent.
Other multi-purpose ATFs: Many other manufacturers offer fluids under generic terms like "Multi-Purpose D-III/M ATF" or "Dex/Merc" which are designed to be compatible with the original Dexron III and Mercon specifications.

Important considerations

Dexron VI: While Dexron VI is the newer standard and is backwards compatible in many GM transmissions, it is often a different viscosity and may not be suitable for non-GM vehicles originally spec'ing Dexron 3. Check your vehicle's manual, but for many older vehicles, sticking to a fluid that meets the original Dexron 3 specification is the safest bet.
Mercon: Dexron 3 fluids often also meet the Ford Mercon specification. Look for fluids labeled "Dexron III/Mercon" or "Dex/Merc".
Always check your vehicle's manual: The best way to ensure compatibility is to consult your vehicle's owner's manual for the correct fluid specification.
