So when I start the car from a cold start, like sitting overnight or a long time, I get this grinding/vibration,from what seems to be the bellhousing area of the trans. *its a 5spd
the shifter shakes and vibrates and shit then once the car is running for a few seconds the vibration goes away but the grinding noise is still there.

If I go up or down hill when its cold the grinding gets louder,

when its warmed up, it doesn't do it.

If I make a hard slow right turn it sounds the worst (Cold)

When its warmed up, I get the grinding noise over big bumps, and speed bumps

-I'm leaning towards the starter, you know the pinion gear on that armature not returning all the way, or staying in place.

someone said motor mounts?

what do you guys think
