Chevrolet Traverse Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2018-2024 (3.6L V6 / 2024+ 2.5L turbo) Chevrolet Traverse.
In short: Chevrolet Traverse transmission fluid: 9-speed Dexron-VI ~45,000-97,500 mi (sooner if towing).
| Transmission Fluid interval | 9-speed Dexron-VI ~45,000-97,500 mi (sooner if towing) |
|---|---|
| Engine / drivetrain | 3.6L V6 (LFY) or 2024+ 2.5L turbo; dexos1 0W-20; 9-speed auto |
| Model years | 2018-2024 (3.6L V6 / 2024+ 2.5L turbo) |
Why it matters: Transmission fluid lubricates and cools the gearbox. "Lifetime fill" really means "lifetime of the warranty" — heat from towing, hills and stop-and-go traffic ages it much faster.
A drain-and-fill (not a flush) is the safe approach, especially on higher-mileage cars. Use ONLY the exact fluid spec for your transmission — the wrong fluid can ruin a CVT or automatic.
Chevrolet Traverse note: The 3.6 V6 is a long-plug-interval (~97.5k), low-fuss engine; the 2024 redesign switched to a 2.5 turbo, which will want closer attention to oil and (eventually) plugs.
FAQ
How often should you change the transmission fluid in a Chevrolet Traverse?
9-speed Dexron-VI ~45,000-97,500 mi (sooner if towing).
Should I flush or drain-and-fill the transmission on a Chevrolet Traverse?
Prefer a drain-and-fill. A pressure flush on an old, never-serviced transmission can dislodge debris; a simple drain-and-fill (repeated if needed) is the gentler, widely recommended option.
