Engine trouble
4 weeks ago my SS developed a vibration...since then I've replaced my underdrive pulley and flywheel (both needed replacing) and i still have this vibration. so externally there can't be anything causing this vibration..
This vibration occurs throughout the whole rpm range, both as the revs up and down. Under load is when you really get this harsh vibration ( but still present at in neutural), it causes the shifter to rattle , its that bad, not smooth at all. But the engine isn't breaking up, still seems to pull fairly good, and idles fine. Hasn' thrown any codes.
Any idea from you guys whats happening here?
Could this be electronic?
I'm lost and frustrated.

I checked the mounts and they are fine...but i forgot to mention that the car doesn't sound right...sounds like its muffled...being helled back kinda off., but seems to still pull fine, maybe just a slight hesitation just when you punch it, but idles like it all always did.

Did you take the motor mounts out to inspect? If not thats compress rubber in metal it will hide cracks. Also did u replace the tranny mount? if so did u aline the bolts any. And how about the drive shaft is there excessive play in it? Simply just twist with your hand with the e brake up it should not move at all.
