2500! Whoa! that sucker must have been slipping the whole way!Look at the pucks, they're almost gone. So in addition the checking the diaphragm very carefully, the release system needs a good going over.
Now I'm not accusing anyone of anything here, but someone that's slips the clutch excessively will have the same fast and hot wear.
I'm sure you know that puck style clutches are best for getting engaged ASAP.
Also note that the pucks are not wearing evenly, so apparently the pressure plate is engaging more on the outer edges of the disc.
This could be an indication of engine/trans misalignment. (could be)
