Found this old thread. I’m new to turbo engine powertrain and of course Ecoboost and 10R60 transmission, so still getting used to new things. I’m hearing the same transmission whine as described above from my 2.3l, especially during initial acceleration and approaching to stop. If I rev the...

Thank you! I did some search, it appears to be the low pressure fuel line using a quick push on connector. Driving on the quiet country road is when I hear the turbocharger the most.

Thank you. I briefly checked the connections during lunch break, things that I could reach from above seemed to be tight and in position, will look into more details. I was trained in music theory for a few years, so my ears are pretty sensitive to sounds. BTW, your green Everglade looks...
