This could be the result of several different things. Do the basics first. Check the fluid and make sure it is full. If the check engine light has come on, have the computer scanned to see if there are trans codes stored in it.
NOTE: If you haven't serviced the transmission for a long period of time and the fluid is really dirty, you may have a filter that is plugging and causing low pressure in the unit.
