Hey everyone. I'm back. I have an 02 Chevy Suburban. A couple days ago I noticed it was making a LOUD rattling, clanking noise from under the truck. I crawled under the next day, and left the engine running so I could find the noise. I worked my way back to the transmission and it is REALLY loud right underneath the transmission pan. I have no idea what the problem could be. Does anyone have any ideas? Thanks !
