Jeff,
I do not think anyone has really answered the most important question;"does
that mean I am missing something".

Just a WAG but I would say yes, you are missing something, given the facts
that have been presented.  There are two different parts available, the one
for the automatic has an extra nipple. I assume for the transmission cooler.
Does your van have a one?
