Help!! Looking for a honest mechanic!!!!My 2008 Nissan Altima service engine light went on. I took it to auto store to have my engine scanned. It came up codes for transmission and Cadillac ( sp) converter. I had no signs of transmission issues while driving. However, I did notice today some transmission fluid on my garage floor. I went to local mechanic and he is telling me his reader is saying I have to get a rebuilt or new transmission. I am hoping someone can recommend an honest mechanic knowledgeable with converters and transmissions. Help? I am having a hard time believing I need a new transmission. So appreciate any help!
