Annie, are you talking about the differential section or the automatic
section?  The differential section uses gear oil and is filled by a
large plug in the side of the differential.  The automatic section uses
Dexron ATF and you fill it through the dipstick tube.  You must have the
van sitting on a level surface.  You need the transmission to be fully
warmed up and in Neutral with the van running while you check the
level.  Do not overfill.  I use a funnel tube that you can buy at
Walmart that screws on to the individual ATF bottle and allows you to
turn the flow on and off.  You can get these for very little money.
Hope this helps.
