Need suggestions from the Phoenix area folks...

I'm in the market for a new mechanic for the 2003 PT Cruiser. The mechanic my father used and trusted has retired. Our second has really let his quality go down hill. I have work done from him on 4 different occasions on 2 different cars and have had to go back to have him fix what he fixed.

Currently my mothers Cruiser has a bad tranny leak and I don't trust myself to try to do the work plus I don't have the garage space to do it in.

So for you Phoenix area folks, I live in Gilbert. Any mechanics or transmissions shops near my are that you trust? Thanks!
