Chrysler Pacifica Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2017-2025 (minivan) Chrysler Pacifica.
In short: Chrysler Pacifica transmission fluid: 9-speed auto (948TE): factory fill-for-life, no scheduled service (PHEV eFlite EVT also no scheduled fluid service).
| Transmission Fluid interval | 9-speed auto (948TE): factory fill-for-life, no scheduled service (PHEV eFlite EVT also no scheduled fluid service) |
|---|---|
| Engine / drivetrain | 3.6L Pentastar V6, 0W-20, 9-speed auto; or PHEV (same V6 + eFlite EVT) |
| Model years | 2017-2025 (minivan) |
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.
Chrysler Pacifica note: The PHEV uses the same 3.6 V6 but with the eFlite electrically-variable transmission (no scheduled fluid service), and its 10yr/150k coolant flush covers three loops — engine, power electronics, and the high-voltage battery.
FAQ
How often should you change the transmission fluid in a Chrysler Pacifica?
9-speed auto (948TE): factory fill-for-life, no scheduled service (PHEV eFlite EVT also no scheduled fluid service).
Should I flush or drain-and-fill the transmission on a Chrysler Pacifica?
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.
