Good day all. I've read threads and can't figure out my issue. I have a 2001 Expedition EB 4.6L V8. When I start my truck there's a loud Mac Truck sound and it gets louder with acceleration. I used to be able to punch it and get up and go. Now, it sounds like a super fan, high rpms with no speed, loud belt squealing, downshifting sound, then it'll shift. Please help. Already broke as it is.
