I originally posted this picture, asking if my transmission mount was supposed to look like this.



Although I received several assurances that this was not a bad sign at all, it now turns out that the only way this bolt can be backed out of the trans mount is if it has completely seperated; which is exactly what happened with mine. It was so bad, in fact, that this condition completely destroyed my driveshaft U-Joint at the transmission.

Replacing both the U-Joint and mount has my truck running like a Cadillac. No more vibes at all.

Long story short: If that bolt is not snog against the mount, your mount is completely f&#%ed.

 

yes I has the same problem last summer......glad you found your source of the vibration.....I haven't been so lucky yet
