I have a 2008 manual 350z
When I start the car it’ll make a air like grinding noise around the trans area and it’ll go away, also goes away if I gas it at all. When I put it in gear and accelerate it’ll make the noise anywhere from 500 to 2400 rpm and will stop past that, no codes pop up at all and the only thing I’ve done to the car is cut the muffler off, haven’t put pipes on it but am planning on welding more. I have no idea what this is and need some help. Any ideas?
