Brummie, interesting story and I'm subscribing because I have a 2015 6.0. Good luck to you with your tranny, hope it comes out ok in the end. No problems yet for me but I am just starting to tow with it so I'll keep an eye on things.
Second question, can you spill the beans on the dash cam set up you have? What a great tool for checking on things like dealerships and other situations when your truck is not right under your thumb. I am a newbie to dash cams so please speak slowly and write with crayons :)!!
Thanks.
