Kia Forte Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2019-2024 (BD) Kia Forte.
In short: Kia Forte transmission fluid: IVT (CVT) inspect — change proactively ~60,000 mi; GT 7-DCT fluid inspect ~?
| Transmission Fluid interval | IVT (CVT) inspect — change proactively ~60,000 mi; GT 7-DCT fluid inspect ~? |
|---|---|
| Engine / drivetrain | 2.0L Nu NA or 1.6L turbo (GT); 0W-20 synthetic; IVT (CVT) / 7-speed DCT (GT) |
| Model years | 2019-2024 (BD) |
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 Forte note: The base 2.0 pairs with Kia's IVT (a CVT) — refresh that fluid proactively (~60k). The GT swaps in a 1.6 turbo and a 7-speed dual-clutch, which wants earlier plugs and its own fluid service.

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