tranny issues, any advice?

Hello all fellow Corolla(ers), I have an issue that needs fixing. I have raced my corolla, without parents knowledge and now the tranny clikcs and makes a really bad noise when I put it in reverse which adds to my fathers suspicion, its ony in reverse and idling, however the reverse gear sounds worse than idling, I was wondering if anyone has any ideas how to fix this: tranny swap? repair? replacement? And if so how easy is it to replace the tranny, im talking about reoval and reinstallation...well anyone with help please get back to me thanks.
