I dont know if you guys had this problem but every time i start the car and start driving it something rattles like something is lose it seems like its coming out of the tranmission i dont know if i need a new clucth or something they told me that my clucth is lose and i need a new one with a flywheel:confused:

Maybe a exhaust heat sheild? Take a look under the car and see if anything is loose around the center between the transmission or oil pan. If so, it can just be cut off.
