While putting back the transmission rear case housing on the transmission, I notice the insulation (same material as under the hood insulation) on the transmission tunnel body above the transmission is rather torn and need to be replace. I did some research on this issue. Somebody said it is a tunnel piece, part #1246100671. So I looked it up. No image . No, it is not a splash guard, either. Something tells me it is not right. In addition, supposedly made of plastic and that is not I need. Does anyone out there knows what I am writing about? Part name and part number is greatly appreciated
