How do I refill the automatic transmission fluid on a Volkswagen Jetta and what type of fluid do I use?

It takes VW G 052 162 A2

As far as refilling it, the manual says it is lifetime and only to replace if repairs are done. If you already drained it, there is a fill port that you feel till the fluid is level with the fill hole. It is located about 2/3 of the way up in the trans near the left front tire. I tried to get a picture but it is copyrighted and I can't. Make sure not to over or under fill the trans.
