I have almost 100K mi on my van and have not had any trouble with the transmission. But I am concerned that the fluid has never been changed. I was wondering if you think I should change the fluid or leave it as is. It is dark but does not smell burned. I was planning on simply draining the fluid from the pan and refilling it. (about 4 qts from what others have told me.) Do you have a better way of changing the fluid? What type of fluid do you recommend I use to refill it with?

Your plan sounds good to me I would use Amsoil synthetic ATF.
