2017 EB 3.5L 10 speed transmission - I am having a noise in my truck that I am thinking about taking it into the dealer while I am still under warranty. I am hearing a noise when i slow down. It sounds like it comes from the rear center of the truck, but not certain on that. It doesn't sound like grinding brakes or anything. The best way I can describe it is a "rotational rubbing noise". I did a search on the forums, but couldn't find exactly my situation. It's not a screech or grinding really from the ICMs. I saw the video post on another thread.

Any ideas?

I had a similar situation with my 2017 ecoboost. My was different in that I heard it from the front end but otherwise as you describe. It has been doing it for a few months on and off. When I brought it to dealer #1 I got the dreaded "could not duplicate". Thanks to this forum I had it fixed today. There is another thread about this (on here somewhere) that told me what to tell dealer #2. When I mentioned the noise along with saying I read about a vacuum line not working correctly the SA immediately said "oh ya there is a TSB about the IWE". It took all day but it seems the problem is now fixed.

Could you possibly find that thread for me so I know what exactly to say to my dealer?

make sure your IWE check valve is the updated blue and white one. The black and white ones fail.
