Currently own a very rusty,200,000 mile 99 318 Durango with a rebuilt trans from 40000 miles ago. I am considering buying a 2000 4.7 Durango that is extremely nice but needs a trans. Can I use the 99 trans? I've never posted on here yet, but from my investigation of many other forums, this seems to be a very knowledgeable group! Thanks in advance!
