I have a 2010 Mazda CX-9 AWD with 37000 mi. When the car had less than 20000mi two years ago, I was told it had dirty transmission fluid. I took it to another shop for second opinion and was told the fluid was normal for the mileage of the car, so I didn't do anything.
Early this year, the car stalled once in the parking garage at work. I took it to the dealership as a precaution. They didn't find anything wrong other than dirty transmission fluid and changed/flushed it. For the last 3 days, I noticed faint buzzing sound when gear shifts. I can only hear it in quiet streets at work when I first drove it out of the garage in the afternoon. After driving less than half a mile, I can no longer hear it.
I bought the car new 4.5 years ago, so I hope anything major will still be covered under powertrain warranty. However, when I brought it in last time, I was charged a "diagnosis fee" for a total of almost $500 to just change the fluid. I was able to negotiate a discount after going back and forth with the sales person over the phone for over an hour, but still paid close to $400. Apparently, he had to "talk to the parts department" several times, reminding me car salesman talking to their managers... I'm not sure I want to go through that again. Should I take it to (another) dealership or a transmission shop (the AAMCO commercial comes into mind)?
Thank you for your help!
