I dont know what's really going on but whenever I am driving and giving it gas with the clutch engaged, it make a clunking or thumping sound. This only happens when I change gears and give it gas, or let go of the gas and press it again with the clutch engaged.

So i lifted it up and decide to spin the wheel while it's on a jackstand and this is the result. When I engaged the engine change disengaged and reengaged the clutch it makes a sound? anyone have any idea what it could be?

The problem started before but after running into some pothole it stopped making that sound while driving, but i hit another pothole and it started again. I kinda wanna just get rid of that sound all together =)

Now on to the solution, can it be the motor mount? or is it something with the transmission?

here's a video of the car when it jacked up, any help would be appreciated.

throw out bearing

Yeah, it sounds like it.

so take apart the transmission and fix?
