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

Should I flush or drain-and-fill the transmission on a Chevrolet Trax?
