I just got this 2007 Mazda6 S Sport Value Edition for free from a family member. It has an automatic transmission.
While driving it in a parking lot I noticed that the car was make some kind of a rattling noise whenever I start accelerating slowly from around 1000ish rpms. After that the noise disappears. The first time hearing something like this was in a Prius I rented, though I don’t think this affects performance at all. I am wondering if this is normal?
Also the car has being sitting unused for about a couple of months before I picked it up. I noticed immediately a burning smell after driving it, somewhere under the driver side, which makes me suspect if it has something to do with the transmission. I know very little about fixing cars of course but I also own a manual transmission car, and this smell kinda reminds me of a burning clutch.
I drove the Mazda 6 from Utah to San Francisco. The car drives great. The transmission seems to work fine. No slipping. Driving around those hills in San Francisco just fine.
Would like to know your opinions about this. Thanks!
