If you slid straight in, my guess is that you damaged the radiator support and hence, the radiator. It is strangely exposed.

If it's the support, the noise is probably related, fan striking the radiator or something like that. Have you looked under the hood yet?

The transmission and clunk...I'm not sure. If it's the support, perhaps a cooler line is also bent/pinched...but this is all speculation. The clunk coils have been a flex disc, and maybe the impact was enough to cause it to tear and then fail.

Good luck, hopefully it's not too ugly.
