Well, I had to call the dealer today (since they didn't bother to call me) and they said that they still think it's the clutch and that I need to authorize $850 worth of labor to look into it further. I explained to them that I had the clutch replaced, and that the stock clutch disc, pressure plate, and pilot bearing are in a box in the back seat. I tried to talk directly to the tech since the service writers had no idea what I was talking about, but they don't let techs talk directly to customers. They said that they think it's the clutch spline (which it's not; I saw it first hand and it's immaculate). I understand that they have to check everything and cover their ass, but they are making it as difficult as possible.
I tried to explain to them about the known problem with the LSD and that I have all kinds of info on them and how they fail. When I suggested that they check the limited slip differential, the Service Director said "you mean the rear end?"
So I said "No, front wheel drive cars don't have a 'rear end'. I'm talking about the limited slip differential that comes standard on all MazdaSpeed Proteges."
The service writers are the only people who have been even somewhat simpathetic to my situation. The sevice director doesn't know the first thing about cars. To top it all off, I can't get a loaner car from them until they determine that it's a warranty issue. You would think that they would put some priorety on my car after all the s*** they have put me through already, but no.
I am ready to pop. So much for a merry Christmas.
