The clutch pedal no longer has resistance when pressing it in, it can be pressed all the way to the floor and it's much easier than it was before.
There's fluid around the clutch pedal that looks like it's dripping from above the pedal area.
When pressing the clutch pedal in it doesn't depress the same as before. In some cases the pedal will be more difficult to press and in others it will press much more easily. The way that the pedal responds after being pressed in can also change and take longer to return to the normal position.
Changes between gears have become difficult, the gearstick no longer moves freely between gears, it sometimes seems to get stuck or won't go into a gear properly.
