The 2017 Chevy Traverse requires Dexron VI automatic transmission fluid. Dexron III and older fluids are not recommended; use Dexron VI or Dexron VI-H that meets GM specifications.
GM manuals for the Traverse’s 6-speed automatic transmission specify Dexron VI as the baseline fluid, with Dexron VI-H as an acceptable high-heat variant. This article covers the correct fluid type, how to identify compliant products, and maintenance considerations to keep your transmission shifting smoothly.
Recommended transmission fluid type
The following fluids meet GM's Dexron VI specification and are commonly used in the 2017 Traverse's automatic transmission.
- Dexron VI (Dexron-VI) — the standard specification required by GM for this transmission.
- Dexron VI-H — a high-heat variant that remains compatible with Dexron VI transmissions under GM specs.
- Brand-name Dexron VI fluids that explicitly meet GM Dexron VI specification (for example, Castrol Transmax Dexron VI, Mobil 1 Dexron VI, Valvoline Dexron VI, or other products labeled as Dexron VI compatible).
When selecting a fluid, verify that the product label states Dexron VI or Dexron VI-H or that it meets GM Dexron VI specification. Using a fluid with a different specification can affect shifting and durability.
Service intervals and fluid changes
Here are general guidelines for maintenance and servicing the Traverse's automatic transmission fluid, noting that exact intervals may vary by model and driving conditions. Always confirm with the owner's manual or a GM dealer.
- Check the owner's manual for the official service interval; GM typically recommends a fluid change every 60,000 miles under normal driving, with more frequent service for severe duty (towing, extreme temperatures, or frequent stop-and-go driving).
- Perform a pan drain and refill as a basic service to replace a portion of the fluid; a full flush or system-wide replacement may require specialized equipment and is often done by a shop or dealer.
- Replace the transmission filter when performing a pan service if your vehicle's design requires it; use a genuine or OEM-grade filter kit for the 6-speed automatic if applicable.
- Avoid mixing Dexron VI with other ATF specifications (e.g., Dexron III or Type F); if you are unsure, replace with Dexron VI rather than mixing fluids.
- If your Traverse is equipped with a sealed transmission (no dipstick) or you experience shifting issues, consult a professional to check the fluid level and condition with the appropriate diagnostic tools.
A regular schedule that uses the correct Dexron VI fluid helps maintain shift quality, temperature control, and transmission longevity.
Practical tips for buying and changing transmission fluid
What to look for on the bottle
When shopping, look for labels that indicate Dexron VI, Dexron-VI, or GM Dexron VI specification. Some brands also offer Dexron VI-H variants labeled as high-heat options. Avoid fluids labeled Dexron III or Type F for this application.
If you plan a DIY change, ensure you have the correct capacity, a compatible filter (if your vehicle has one), a drain pan, new crush washers if needed, and follow proper safety procedures. If in doubt, have a professional perform the service.
Summary
For a 2017 Chevy Traverse, the recommended transmission fluid is Dexron VI (Dexron-VI). Dexron VI-H is acceptable, and many major brands offer Dexron VI fluids that meet GM's specification. Always check your owner's manual or with a dealer for the exact requirements and service intervals, and use the correct fluid to ensure smooth shifting and transmission longevity.
