Whenever I release my clutch at low rpms (under 2k) with very little throttle, there is like a metal-to-metal "clunk", the feel is as if there is a slack or gap between moving parts. It's hard to describe, but does anyone has the same problem?

 

Is it a heavy clunk(you feel it) or just some small noise?

Check your torque(motor) mounts for breakage and wear. If not that you might have some worn down teeth or gearing in your trans or your differential.

Could also be an axle or some LCA bushings.

Check the easy stuff first, jack up your car and pull hard on your wheels all directions around the wheelwell and feel for play.

 

borrow a method of recording this. it could be so many things. do like @G said, check your manual transmission fluid level, try doing it with the car on and off also, and report back with your findings. try to give is as much information as possible about related things like anything weird about the clutch working or turning on or off power or any little thing you find.

 

I'll do a check on the fluid and also try to inspect my suspension components.

The clunk is similar to the sound you hear in older cars when the A/C compressor kicks in. Kinda felt in the acceleration also.
