Re: Loud scraping noise (Metal to Metal)
blacksnack is right, if the noise is comeing when the engine is running and car not moveing then its in the mechancial moveing parts, alt. w/pump/ tourqe converter,ect.
start elimnating them to find the noise most high point. as far as it stopping when on ramps? how much incline you talking bout? and has the trans ever been replaced?
if so look under the car while on stands check the splash pan make sure converter bolts not rubbing it.
