The transmission fluid dipstick on a 2003 Chevy Malibu is typically located on the passenger side of the engine bay, near the firewall. However,
it's crucial to consult your owner's manual. The exact location can vary slightly depending on the specific transmission type (automatic or manual) your Malibu has.
Don't rely solely on online information; your owner's manual will have a diagram showing the precise location and instructions for checking and adding transmission fluid. Incorrectly adding transmission fluid can damage your vehicle's transmission.
