Kia Telluride Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2020-2024 (3.8L V6) Kia Telluride.
In short: Kia Telluride transmission fluid: 8-speed auto service ~60,000-100,000 mi (sooner if towing).
| Transmission Fluid interval | 8-speed auto service ~60,000-100,000 mi (sooner if towing) |
|---|---|
| Engine / drivetrain | 3.8L V6 (Lambda II, NA); 0W-20 synthetic; 8-speed auto |
| Model years | 2020-2024 (3.8L V6) |
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 Telluride note: A simple, naturally-aspirated V6 with a long ~96k plug interval and no turbo to baby — among the lower-maintenance 3-row SUVs. Just don't forget the short second coolant cycle.
FAQ
How often should you change the transmission fluid in a Kia Telluride?
8-speed auto service ~60,000-100,000 mi (sooner if towing).
Should I flush or drain-and-fill the transmission on a Kia Telluride?
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.
