I have a 2016 super crew 4x4 Sport, with the v6 EcoBoost and 32000 miles. Today was driving about 40 mph and took my foot off the accelerator, coasting for a bit and still in drive. When I went to speed up again, I heard a clunk as i gently pushed the accelerator. Figure this has something to do with the engine and transmission syncing up, but the clunk sound is new. Did have an oil change the day before, but they didn't service the transmission or anything. Any idea on what this could be?

 

Normal driveline lash? I think we all get clunk in the driveline if you line up the power just right.
