J30 sounds like scraping flywheel, now A/C doesn't work at the same time.

[bumble]

Hello, I have a 1993 J30t with a completely rebuilt transmission 2 yrs. ago and has worked fine. 2 weeks ago I would get into car and start in Park and hear a constant sound like a "metal fan blade scraping its housing" medium to high pitched. When I changed to R it would do an extra scrape sound, then down to D would do another seperate scrape. It would last for a few minutes and then noise would stop before I drove off. The fan looked fine,belts fine, etc. When I tried to listen where noise was coming from it sounded louder listening from below car and while listening above engine it was at the back of engine on the transmission side.

Since I assumed transmission I took it back to my transmission guy. And he didn't hear it or could he recreate it. My fluid looked great but it was getting close to miles of transmission fluid/filter change so I had him drop pan and everything looked great. He looked further and said that my starter was sagging where it meets the transmission and was probably catching flywheel as he saw polishing/rub marks on flywheel and some minor metal. He then replaced starter and it worked fine for 2 weeks.

Now the noise has come back twice and only when in Park and I do hear another quick scrape when I shift through neutral to D and no more sound. Back to Park, same constant sound. And now when this occurs the A/C completely stops blowing air. No fan, nothing. So I drive to mechanic with A/C not working the whole time then I put in park and no more noise and A/C starts to work. Luckily the second time I took it in one of the mechanics got to hear noise. I turned car off and he brought another mechanic to listen, I turned it back on and everthing worked. DAMN! They say they checked the starter and everything looks good and they couldn't recreate the noise. So here I am with no car and wondering if it ever even needed a starter? And these guys are transmission mechanics but that was what I thought the problem was. I've tried to be as specific as possible. Does this problem ring any bells? Please help, Jay
