Strange issue with 2010 Mazda 6i
 

Has the 2.5l four cylinder and the 5 speed auto trans. Has the transmission serviced at the dealer, now after that was done I notice a smell like transmission fluid being drawn into the inside of the car after it's been driven a while. Looking under the hood, I notice that the smell is strongest coming from the area of the transmission dipstick but I cannot find any leaks that are obvious. Strange, and annoying. Any ideas?

They may of spilt oil & not cleaned it up. Take it back.
