So my 06' base has a fairly new clutch (5000 miles or so) and I've noticed when the engine/trans get hot after about 20-30 minutes of driving the engagement point in the clutch travel starts to go to the floor. Depending on how hot it is out it can go pretty low, maybe 3 or 4 inches lower than normal. After it cools off its fine. I already had the fluid replaced, thinking about trying again, but what else could it possibly be if its doing this with fresh fluid?

 

You can also adjust the rod behind the the clutch pedal... It's what actualy pushes into the master cylinder... I have done this on a few cars with the same issue...
If your pedal is sticking adjust the rod out from the pedal, so I belive it would be clock wise... Also don't go to much about one to two full turns start with one...
Hope that helps...... Also look up adjust clutch pedal in the service manual pdf files....

just posted this on another theard this will also change were the clutch engages/ @ wich height of pedal

 

You've got air in the line. Adjusting the pedal per ^ could cause a problem when it's cold. Get a pressure bleeder, and get ALL the air out of the line. Do a search for more info.
