I have a 2007 Escape AWD. Whenever I put the car in reverse after a "cold" start it makes a loud rattling sound. The sound goes away in park or drive, and will not happen after driving the car for awhile and starting it warm. Has anyone had similar problems? I am no car expert and I am a bit worried it could be a transmission problem. I'm hoping it is just something that is loose that is causing the rattling though. Any advice would be great.
