Question regarding TSB
 

Hey guys Ive recently started getting a vibration in my car once it hits the 5th or 6th gear in auto transmission. I researched the website and there was a thread about it.

The OP talks about a TSB but its not a recall, when I called Mazda today, they said they havent heard about this TSB and asked me what the name of it is, and said it might be a US TSB, and help guys?? what should I do?

Print it up and show it to them.

And TSB's are only covered under warranty. If you're out of warranty, you'll have to pay for the service, but it's still a good troubleshooting technique.
