Hello, I Have a 95 camaro z28 and iam getting a shudder-vibration even in park when i rev rpm it will shudder-vibrate i looked at harmonic balancer and it has a slight wobble so i replaced it but the slight wobble and shudder-vibation still there. Engine dosent miss or run rough runs great but at high speeds it vibrates like something is not balanced. Can someone please help iam lost! Thanks in advance! I Want to add that i have replace engine mounts and the vibration at high speeds seem to come from trans area.

 

what kind of transmission mount do u have.

 

auto or manual, maybe lost a convert, clutch bolt.

 

thanks arrow, i was just wondering if he replaced the trans mount with polly. that will do it to. been there done that. shoulda said that to start with huh. slap my face and call me stupid im learnin.

 

no prob craby, we're all here to help right. I think it would depend on how bad the shudder is to really narrow it down.

 

I have a automatic....and i did replace mount with polly,but the shudder happens in park too.

 

you sure you didn't loose a mount mount bolt?

 

How long have you had the car? And has it always shutter-vibrated like that, or did it just start?
How many miles does the car have?

 

I have had the car for two years,but my son drives it so i dont know if its always been there or not....the car has 117000 the mount looks like its on there good not missing any bolts.

 

mine did too. did it start when you changed the trans mount. i blew the trans mount, got a poly it started the vibration changed back to a stock one and all better. the solid poly transfered the motor vibrations bad. i hear the motor mounts dont do it but i dont know. it was a little better if the stud that is screwed into the trany mount was backed out so it was not bottoming out on the steel at the bottom of the bolt/stud hole. used some thread lock and let it dry a little while before tightening. it was still bad enough that i changed to the stock style. i do have a poly torque bar bushing that works great and does not transfer vibration.
