Know of one?

I've been jumping through hoops with my car, which is at my buddy's shop. I had a guy "rebuild" the trans, but I think he just stuck a kit in it and didn't check anything.

The car has a vibration and some other problems like staying in park on a hill that has me thinking a bearing is bad, or a shaft is bent, or something is out of round with the drum or something.

Anyone know of a GOOD transmission shop that knows 904s and not just Chivvy stuff that would take the time to figure out what is wrong with mine?
