transmission fluid on 1996 Volkswagen Passat

how do you check the fluid level and add fluid

Asked by for the 1996 Volkswagen Passat
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........
