I have noticed that sometimes when I shift there is a humming/moaning/vibrating noise that seems like it is coming from the trans cooler. It sounds like a restriction in line. At times when in park the noise will continue for a little while, during that time I can feel the trans cooler lines vibrating.

I have left the truck at the dealer for a day any they could not replicate the issue. Has anyone had something like this before or have an idea on what it maybe?

And this is with a 2013 FX Eco.

 

Yep have the same problem on my 2013 eco fx4. Just got it back from dealer gave me the same answer could not replicate it. There is another thread on here about it where someone had it fixed with TSB 13-04-15. I gave my dealer this info and they still couldn't fix it.

 

Hi FX13ECO and bama1080,

Reach out to me via PM so I can look into this. In your message, please include your full name, best daytime phone number, VIN, mileage, and servicing dealership. I'll start researching some options.
