Just a thought here, is it wise to change the Tranny fluid at all? The manual says it is not needed. I had a 86 Caravan that had 110k when I sold it, never changed My 96 Winstar with 98K and just traded my 01 Windstar with 62K on it for a 04 T&C. None of these have ever had the tranny fluid changed.
I can see why one would change the fluid, but then the manual even says it's not needed as well.. I never change the Brake or power steering fluids...
