Clutch clunks when pushing it in - this normal?
My 03 6MT G35 i have had for few months now.
Not sure if i am imagining this or not but i swear it wasnt always like this..
I push my clutch in and as it is almost down to the floor and i feel a bit of resistance (like a clunk), if i push down real fast i can feel two little clunks (car is sat in drive way not even turned on). When driving i also feel this clunk..
Car has done 17,000miles, im about to do a service which in the book is just oil + oil filter and top up power steering.
Should i do clutch fluids? they are on the minimal end of the reserve until the hood..
Plus is this resistance thing normal? Do i have something that needs looking at?

You dont hear anything, just when pushing it in its like it hits a very weak wall/bump and then continues... What oil can be used to do the flush and use replace the old stuff?

Clutch fluid is actually brake fluid. The OEM recommended fluid (in the repair manuals) is DOT 3. Here, check these links out. One is the clutch section of the repair manual, and the other is a video on flushing/changing clutch fluid.

What you might be experiencing is the switch for the clutch depression sensor.
The clutch depression sensor makes sure your clutch pedal is pressed down (so the clutch is disengaged) when you start the car, which prevents the possibility of starting it while the motor is connected to the wheels.

you guys are all wrong.
It has nothing to do with clutch fluid or slave cylinder.
The clunk noise is coming from the transmission fork area.
When you depress the clutch pdeal, your slave cylinder pushes the fork on the tranny.
I confirmed that the noise is coming from the fork area. I think it's most likely from the throwout bearing, fork, pressure plate area inside the tranny.
There's no option to fix it unless you replace the whole clutch assy.
just depress it really slow, and you won't hear it.

Click the video below to play it
EDIT
took a video. Ignore the sound as it is fully release and the initial sound as pressing in. Listen for the bump or little bumps as i push faster. Also notice that when not full release when bring it back half way and push in again the clunk is not present... Does this help Nate?
