All us stick shift veterans know about engine lugging - that light vibration when you’re in too high a gear for your speed. My2021 1.5 turbo Equinox makes that sound when running at about 1200 rpm at 30mph or less, even when coasting along. I noticed the same thing with my older 2.4 NA Nox as well. Has anyone else experienced this?

Yea I have noticed the torque converter locks up. Eco mode makes it lockup at a lower speed/rpm too

I have experienced the same behavior when RPMs are in the 1,100 to 1,300 range when driving at slower speeds, so I believe it's just vibration, and the TSB below addresses this. My liftgate also squeaks when going over bumps, so I'll be taking a look to see if the striker is out of adjustment.

Trans. logic tuning and engine lugging to get the holy grail of MPG.
