Default 96 vortec vibration

I've got a 96 k1500

Has an obnoxious vibration and I can't find the source. I'm hoping someone can help me diagnose this. It's only present starting at 2200rpm and ending at 2900.

I've looked at the fan/clutch, all is good there. I don't see any bouncing in the harmonic balancer.

I would imagine this could be stemming from the TC or flywheel, but I'm not really sure how to test that.

Are the flywheels weighted?

Any help is appreciated,
Thanks, Kyle
