First off I would like to say hello to everyone on these forums. I have a 2008 V6 mustang 4.0L and earlier tonight I felt a "clunk" towards the rear of my car. I was only going maybe 15 mph and parked to see if I had hit anything. When I looked back, I saw this object lying in the middle of the road. It was also fairly warm which made me think it was indeed, from car. I am not sure what it is, or even if it came from my car.

On the top of the piece, it says:
Ford 6R33-5F295-AA AHA
The metal part seems to have broken from another part, but I can not see from where exactly it may have come from. Standing, it is about 2.5in tall. I can try to describe it better if it would help. Thank you.
If anyone could identify this part, that would be great.
