Well, after gettin getting home from smashin on a few ricers the other night I noticed a slight rattle comin from under my truck. It was only happening under idle or really light throttle. So today on my way to work, I got on it a little and my RPM's were going higher a lot faster than my speedo. DEF feels like my verter is slippin really bad. Good thing is, if my tranny goes out it gives me a good excuse to finally start on a engine/trans swap. I'm gonna go beat on it some more tonight and see if I can "figure out" what's wrong.
