Honda Passport Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2019-2025 (2nd gen, US) Honda Passport.
In short: Honda Passport transmission fluid: Per Maintenance Minder; commonly ~50,000-60,000 mi for the 9-speed (incl. AWD fluid).
| Transmission Fluid interval | Per Maintenance Minder; commonly ~50,000-60,000 mi for the 9-speed (incl. AWD fluid) |
|---|---|
| Engine / drivetrain | 3.5L J35 V6, 0W-20 full synthetic, 9-speed auto, i-VTM4 AWD |
| Model years | 2019-2025 (2nd gen, US) |
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.
Honda Passport note: Like the Pilot/Odyssey/Ridgeline, the J35 V6 uses a TIMING BELT — not a chain — that must be replaced around 105,000 mi/7 yr. It's an interference engine, so a snapped belt wrecks it; this is the one interval you don't skip.
FAQ
How often should you change the transmission fluid in a Honda Passport?
Per Maintenance Minder; commonly ~50,000-60,000 mi for the 9-speed (incl. AWD fluid).
Should I flush or drain-and-fill the transmission on a Honda Passport?
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.
