Jeep Grand Cherokee Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2022-2024 (WL) Jeep Grand Cherokee.
In short: Jeep Grand Cherokee transmission fluid: 8-speed (ZF) ~60,000-120,000 mi; sooner if towing/off-road; 4xe also has e-motor fluids.
| Transmission Fluid interval | 8-speed (ZF) ~60,000-120,000 mi; sooner if towing/off-road; 4xe also has e-motor fluids |
|---|---|
| Engine / drivetrain | 3.6L Pentastar V6, 2.0L turbo, or 4xe PHEV (5.7 HEMI in earlier WK2); 0W-20 synthetic; 8-speed auto |
| Model years | 2022-2024 (WL) |
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.
Jeep Grand Cherokee note: The 3.6 Pentastar is a plug-at-~100k, chain-driven, low-fuss V6; the 4xe plug-in hybrid adds its own e-axle items. As an off-roader, axle/transfer-case fluids are the recurring real job.
FAQ

8-speed (ZF) ~60,000-120,000 mi; sooner if towing/off-road; 4xe also has e-motor fluids.
Should I flush or drain-and-fill the transmission on a Jeep Grand Cherokee?
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.
