I have an 05 5 speed manual with about 50k miles. I notice that the clutch engages and disengages much more smoothly (we are only talking first to second) for the first while after startup. That is later on in the drive i.e when the engine is naturally very warm I must be more careful when releasing the clutch. I dont mean that gears grind but rather the 'release' point for the clutch is...higher. Does that make sense? Is it possible that this could be the consequence of having too much fluid in the hydraulic clutch/brake master cylinder reservoir? Should this level be at the min mark when the car is completely cold...say after sitting all night?
