Good thought David, however in my personal experience when the thrust  
washer fell out the only change was a bit of difficulty shifting,  
sometimes. I recall no change in the clutch travel or pressure.

But Kevin, check that anyway, just to be safe. I do not want to spend  
another day swapping that engine out quite so soon.
