2021 Subaru WRX transmission: CVT or automatic?
Some do: the 2.0L 4-cylinder turbo uses a CVT (continuously variable, 8 simulated steps) and a 6-speed manual; the 2.5L 4-cylinder turbo uses a 6-speed manual.
Key takeaways
- 3 EPA-certified configurations listed for the 2021 Subaru WRX.
- CVTs need CVT-specific fluid - never top one up with ordinary automatic transmission fluid.
- The transmission can differ by engine and drive layout, so match your row by engine size.
