So the dealer called with an update over the weekend. Ford engineers are having them replace a Speed Sensor located inside the transmission. My dealer does not have the part in stock and it needs to be shipped to them. Should have more info Monday or Tuesday.
I also have a 10/27 build, can I ask how many miles your truck has on it now and how many did it have when you picked it up? I have 700 on mine and knock on wood no issues. My truck did have a lot of paper work in it showing things that where checked and a dash reflash, and transmission reflash card, and a paper showing it was driven afterwards. Man I hope they get you rolling soon, I flat out Love my truck! This thing is nothing short of a Beast, want to drive it all the time! Taking it to the mountains Tuesday and Wednesday this week, can not wait! Good luck Bother, hang in there, it will be great!
