This is on my 4th gen daily driver, but i need some quick help. I've got this strange vibration or rattle when I come to a stop and at low speeds. I can feel it in the pedals at times. Motor is fine, might it be a blown tranny mount? I haven't had a chance to get under the car yet.

 

Little more info. Auto, stick? Just when your stopping. How a bout leaving a stop sign/light? Cracked flex plate?? Broken motor mount/ exhaust rattle??
