You need to determine the transmission type first. Check your owner's manual; it will definitively state whether your Sebring has an automatic or manual transmission.
Once you know the transmission type, you'll need to consult a repair manual specific to your vehicle's year and model (2001 Chrysler Sebring) *and transmission type*. These manuals provide diagrams and precise locations. Using a general image online risks getting the wrong location and causing damage.
Caution: Working on a transmission requires some mechanical skill. If you are not comfortable working on your vehicle, it's best to have a qualified mechanic perform the transmission fluid change. Improperly draining or refilling can damage your transmission.
