Vibrating when Stopped in Drive

My cobalt has around 88k on it and this only happens when I'm in drive and come to a stop. It will start vibrating, not horriably, but enough to take notice. Like the whole car is vibrating. If I put it in neutral, the vibrating goes away. Does this sound like loose motor mounts? Transmission issues? Any response is helpful. Thanks!

Mine does it also. I don't think it's a problem. But it's probably the motor and tranny mounts or whatever they're called. That's what I was told at least. I know a lot of people upgrade to after market mounts

Check all of your mounts, thats more than likely the issue

Only had our 06 LS for a week, but it idles smooth as buttah...you'd better check those mounting points b/c something's loose.

Its not the mounting point, but in a manual transmission the shifter will move up and down once locked into a gear and pressing the accelerator pedal...those are signs of the rubber material used in the mounts are basically gone...for yours, its sitting at idle in drive gear.

So it is just the mounts? Engine mounts? Idk if it's this simple or not.. but seems kinda self explanatory to me. Do you just lift the motor enough to get weight off the mounts then change them out?

I haven't studied the underneath of this car a/o yet, but you either (1) lift up from below w/floor jack, remove & replace or (2) hoist engine up with lift then remove/replace. Either way, you're getting some of the pressure off the mounts to get them removed.
