Kia Sportage Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2023-2024 (NQ5) Kia Sportage.
In short: Kia Sportage transmission fluid: 8-speed auto (NA) service ~60,000-100,000 mi; hybrid 6-speed similar.
| Transmission Fluid interval | 8-speed auto (NA) service ~60,000-100,000 mi; hybrid 6-speed similar |
|---|---|
| Engine / drivetrain | 2.5L NA Smartstream or 1.6L turbo hybrid/PHEV; 0W-20 synthetic; 8-speed auto / 6-speed auto (hybrid) |
| Model years | 2023-2024 (NQ5) |
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.
Kia Sportage note: Mechanical twin of the Hyundai Tucson — same chain engines, same long-then-short coolant cycle. The 1.6T hybrid is the efficiency pick; document oil changes for the warranty.
FAQ
How often should you change the transmission fluid in a Kia Sportage?

Should I flush or drain-and-fill the transmission on a Kia Sportage?
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.
