|---|---|
| Engine / drivetrain | 3.5L V6 (2GR-FKS), 2.4L turbo (2023+) or 2.5L hybrid; 0W-20 / 0W-16 full synthetic |
| Model years | 2020-2024 (XU70) |
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.
Toyota Highlander note: The hybrid is the volume seller and adds an inverter-coolant item. Very low-maintenance Toyota V6/hybrid; severe schedule fits most suburban use.
