Where do you add transmission fluid in a Volkswagen Golf?

The manual on my 1997 says take it to the dealer. My mechanic said that's because you need a special tool to access the transmission since there is no dipstick to check it. If you have a manual transmission, look at the part of the transmission facing the front of the car and there should be a hex bolt that requires a 17mm hex socket. That is how you check and fill your transmission. To drain it look for the same type of bolt on the bottom side of the transmission.
