Here's a problem for our collective wisdom.  What would cause the
transmission main shaft where the clutch plate rides on it to become
damaged 3 times in about 25000 miles to the point that the clutch
doesn't release.  The problem was fixed twice at the dealer, replacing
the main shaft, clutch plate and pressure plate, pilot bearing, main
shaft seal, and throwout bearing each time.

The problem develops very suddenly, typically in 50 miles of driving,
maybe less.

This is my vehicle, and I'm wondering how to fix this for good.

Has anyone else out there seen a failure like this, and if so, how did
you deal with it.  What was the Cause?

Hopefully,
