2003 Saturn Ion transmission: CVT or automatic?
Some do: the 2.2L 4-cylinder uses a CVT (continuously variable), a 5-speed automatic and a 5-speed manual.
Key takeaways
- 3 EPA-certified configurations listed for the 2003 Saturn Ion.
- 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.
