* Automatic Transmission: The most likely fluid for an automatic 2000 Sebring is Dexron III. However, it's *crucial* to check your owner's manual or the sticker on the transmission itself for the exact specification. Using the wrong fluid can severely damage the transmission.
* Manual Transmission: If your Sebring has a manual transmission, the fluid will likely be a GL-4 or GL-5 type gear oil. Again, consult your owner's manual for the precise specification.
Do not rely on general advice. Always verify the correct fluid type from your vehicle's documentation. Using the incorrect fluid can lead to expensive transmission repairs.
