Have to drop the transmission oil pan
There is a check and fill plug on the side of the transmission close to the cv axle. It is most likely on the passenger side of the differential. The fluid should be full till it is just before running out of the plug hole.

The automatic transmission fluid in a 2004 Ford Mustang should be changed every 30,000 miles or once a year. The manufacturer has made this recommendation available in the owner's manual as well.
