Hi, all -

This has been going on for about a month now. It seems to only happen when I first start my car in the morning. It starts just fine, sounds just fine - until I put it in reverse to back out of my garage. When doing so, it has some weird rattling sound, like it's coming from the transmission. Once I put it in drive, the sound stops and it seems to be just fine. I think from there on throughout the day, it all sounds find when in reverse (unless I cannot hear it because I'm out in the open).
Have any of you experienced this type of problem? Would you know what the issue could be?

Thanks in advance,

Jon
