how do you check the fluid level and add fluid

The fluid level can't easily be checked.
The vehicle has to be raised , a scan tool is used to monitor the transmission fluid temperature and at the specified temperature (50 degrees centigrade ??) fluid should run out of the overflow/fill port. If fluid does not run out it is to be added during that process until it does.
Unless there is a leak you should not have to add fluid........
under the hood down on the bottom of transmission there is a little dip stick
