So yesterday I was parking and I managed to hit the curve of the road while backing up very slowly ofc. When i hit the curve i all the sudden could not change to any gears other then 1st and 3rd gear. I put it in 1st and started driving very slowly all the sudden I heard some metal clink and I looked under my car and found this part: https://imgur.com/a/85yYq . I grabbed the piece and it was pretty warm, I put in the trunk and drove very slowly home. The car felt normal but the gears were way easier to change and the exhaust is much louder then normal. I do not understand what it is neither have i seen it before.
