Toyota Sequoia Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2023-2025 (3rd gen, i-FORCE MAX) Toyota Sequoia.
In short: Toyota Sequoia transmission fluid: 10-speed auto; inspect from ~30,000 mi; replace ~60k/120k if towing.
| Transmission Fluid interval | 10-speed auto; inspect from ~30,000 mi; replace ~60k/120k if towing |
|---|---|
| Engine / drivetrain | 3.5L twin-turbo V6 (V35A-FTS) i-FORCE MAX hybrid; 0W-20 full synthetic; 10-speed auto |
| Model years | 2023-2025 (3rd gen, i-FORCE MAX) |
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 Sequoia note: This generation replaced the old 5.7L V8 with a twin-turbo hybrid that runs hotter — keep 0W-20 on schedule and do earlier trans/diff service if you tow. The hybrid adds a separate inverter-coolant loop and an HV-battery cooling intake to keep clear.
FAQ
How often should you change the transmission fluid in a Toyota Sequoia?
10-speed auto; inspect from ~30,000 mi; replace ~60k/120k if towing.
Should I flush or drain-and-fill the transmission on a Toyota Sequoia?
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.
