6-speed manual owners: please help - bleeding clutch line

For those of you with manual transmissions:

Can someone point me in the right direction as to where the clutch slave cylinder is located? Couldn't locate it from the top of the engine bay. Called the dealership and they don't even know exactly where it is (either on the transmission bell housing or within the housing itself). I'm trying to bleed my clutch line, as I think there might be some air in it, or it just hasn't been bled before. My clutch pedal gets a bit stiffer after continuous driving, but softens to normal again after letting the car sit for a few hours.

I haven't gotten under the car yet. Wanted to get some input here before I try getting under there.

Thanks everyone!
Chris

Access it from the passenger side of the transmission housing. Look for a hand-removable squareish rubber plug near the bottom of the housing.

Thanks so much for your help. So I'm assuming I'll have to get under the car then huh? Did you have to remove any underbody panels to get to it?

Yeah you have to jack up the car and remove the rear under tray. Make sure you keep filling up the master cylinder so you don't run dry when bleeding. Good luck!

I never would have found the bleeder valve without your help. Thanks a million! Who would think to look behind that dust cap??

Just finished bleeding the clutch (about 100ml), and the difference is literally night and day. The clutch is as smooth as butter. As I was bleeding, the air came out in the form of an aggressive spray. When the bleed was consistent again, I assumed the air was completely flushed out. It took about 8 pumps of the clutch.

Thank you again. As other 6-speed owners have mentioned, this is definitely worth doing. The dealer was charging an hour of work ($145), but I bought the DOT4+ fluid for $25 and did it myself.
