Hello, I think i may have a broken motor/tranny mount. I have vibrations at low rpms and think it may be a broken mount. Can somone tell me what i am looking for in both cases to diagnose the broken mount. thank you. CHRIS,.

 

Bump for some help???

 

They are both solid rubber. I engine mounts normaly break just under the top metal part. You should be able to just the motor just a bit to see if they seperate there.

 

let your car idle with the ac of then turn the ac on if the vibration gets worse its probably a motor mount. Finding which mount it is is a bit tricky especially if the crack in the rubber isn't visible.

 

You might be able to see the brown fluid mark coming down the side of the mounts. It's rust colored.

If you see one of the engine mount broken, chances are the other one is broken too.
