Kevin,

The fill plug is straight up from where the shift lever goes into the case. It's hard to get to with a normal 17mm Allen wrench. You may want to make a tool out of a short 10 mm bolt and 2 nuts. If you go to http://www.vanagonauts.com?catid=101 you can see a picture which of course is worth a bunch of words.

Best of luck,
