Hey guys and gals I've got a great question for ya. I have a 99 expo eddie bauer with 183,000 miles. This trucks runs great, and I am all about the oil changes. I sdo have a question . I haven't changed the tranny fluid in about 2 years. It is not dirty but I have heard on old trannys not to keep changing fluids because of t

he seals setting etc. Should I keep it changed or not??????
