Chevrolet Colorado Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2023-2024 (2.7L turbo) Chevrolet Colorado.
In short: Chevrolet Colorado transmission fluid: 8-speed Dexron-VI ~45,000 mi severe / longer normal.
| Transmission Fluid interval | 8-speed Dexron-VI ~45,000 mi severe / longer normal |
|---|---|
| Engine / drivetrain | 2.7L turbo-4 (L3B); dexos1 0W-20 synthetic; 8-speed auto |
| Model years | 2023-2024 (2.7L turbo) |
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.
Chevrolet Colorado note: The 2023 redesign is 2.7-turbo-only. As a midsize truck, gear oils (front/rear diff) and the air filter matter most if you off-road; the turbo likes on-time oil.
FAQ

Should I flush or drain-and-fill the transmission on a Chevrolet Colorado?
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.
