When to change the transmission fluid on a 2024-2025 (2nd gen) Chevrolet Trax.

|---|---|
| Engine / drivetrain | 1.2L turbo 3-cyl (LIH); 2024 = 5W-30 dexos1 Gen 3 (2025+ 0W-20); 6-speed auto; FWD-only |
| Model years | 2024-2025 (2nd gen) |
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 Trax note: The new-gen Trax is front-wheel-drive only (no AWD) and — unusual for a subcompact — uses a wet belt-in-oil timing belt GM schedules for replacement at 150k mi. Keep oil changes on time; degraded oil shortens that belt's life.
FAQ
How often should you change the transmission fluid in a Chevrolet Trax?
6-speed auto (DEXRON VI); severe service every 45,000 mi.
Should I flush or drain-and-fill the transmission on a Chevrolet Trax?
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.
