Where do i put in my transmission fluid?

[pzujko123]

Hello I have a 2004 Volkswagen Golf GLS 2.0, Im trying to fill it in my transmission fluid because i believe im low on it, I cant even shift gears. so im now trying to find out where to put in my fluid as I cant find it. I looked up videos and only found one and it said the plug is supposed to be under the air filter close to the front of engine but its not there, can anyone help?

Transmission is a sealed unit. It's recommended to have dealer check and add fluid. If you still want to try, I found this link (i did not read and can't verify it's accuracy)
