Subtle shuddering during acceleration

[happypants529]

I've been noticing recently that every once in a while my car gives me a slight shudder while I'm speeding up. It happens right around 2.5-3.5k rpm. I don't see the rpm's jumping around any so I don't think it has anything to do with the engine itself but I don't know what it could be. Any ideas? Also the car is an 09 aveo5 manual trans.

What happens if you hold it in the 2.5-3.5k range and how bad of a shudder? I'm kind of wondering if it isn't just some strange resonance from the engine transmitted through the mounts.

Haven't driven my 09 Aveo5 manual in months due to work travel so I can't remember if mine does it...

You could also check the mounts too and make sure they are in good condition.

Motor mounts? If I drive at a constant speed between those rpm's, its fine. Only during acceleration. And generally it happens in 2-4th gear. Honestly its not that bad of a shudder, just something that's noticeable and I never felt it until the last couple weeks.
