Hi so i was driving around the other day and shifted into 3rd gear and i heard this weird sound like the exhaust got louder. I knew this wasnt the case, but thats what it sounded like. Anyway the next time i shifted into third gear my car made a huge bump and i knew i just broke something. Now when ever the car moves (in any gear even reverse or if being pushed) it makes a sound like something is being tossed around inside the gear box or flywheel. I drove it home and parked it and havent driven is since. However it still makes the sound. The reason i think it is third gear is because while driving it home i couldnt shift into 3rd gear, and 3rd gear was making a weird sound. Does anyone have any ideas as to what to do or where to take it. Im in "Warwick NY 10990". Any help would be greatly appriciated.
p.s. i was not racing or anything just everyday driving.
also i have a stage 3 cluth and lightweight flywheel if that matters
