Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2022-2025 (VB gen) Subaru WRX.
In short: Subaru WRX transmission fluid: Performance CVT: inspect (~30k), severe replace ~24,855 mi. 6-speed manual: gear oil ~60,000 mi.
| Transmission Fluid interval | Performance CVT: inspect (~30k), severe replace ~24,855 mi. 6-speed manual: gear oil ~60,000 mi |
|---|---|
| Engine / drivetrain | 2.4L FA24 turbo boxer, 0W-20; 6-speed manual or Subaru Performance CVT; AWD |
| Model years | 2022-2025 (VB gen) |
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.
Subaru WRX note: Comes as a 6-speed manual or Subaru Performance CVT (different drivetrain-fluid needs). As a turbo boxer, let it idle to cool after hard runs, and keep all four AWD tires matched.
FAQ
How often should you change the transmission fluid in a Subaru WRX?

Should I flush or drain-and-fill the transmission on a Subaru WRX?
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.
