I was having issues with mine. Between three dealerships one said it needed a clutch which i told them to pack sand. The next found the master cylinder leaking and replaced it. I was still having issues of clutch engagement and hard shifting. the Third dealer took the tranny out for me under warranty and found the slave cylinder/throw-out bearing in pieces. Also the pressure plate bolts were loose which there's is a TSB for.
