[Roadsters] Vibration

[Mark]

  The fix was to use a mount other than the urethane - sorry about not 
being clear......my final trans mount is the chevy mount.
I found that the stock mount that was loaned to me eliminated it 
completely...but since it was a loaner, it was suggested I try the chevy 
mount....and it also eliminated the vibration.  In-between the 2, I went 
back to the ES mount (wanted to keep driving!) and the vibration 
returned.  My best guess (guess being the operative word!) is that my 
combination of urethane motor mounts and the ES trans mount just didn't 
play together well (or they transmitted more vibration than I could live 
with).  The softer mounts worked well.
Hope this helps!
