AT Symbol on Mazda 6
 

Hey guys. Anyone know what the AT (auto transmission) symbol on a 2004 Mazda 6 means ? Every morning (or whenever my car is cold), this symbol will turn on. Everything drives fine except when I put it in reverse, my car jolts a little bit. However, when my car has no AT symbol, it reverses perfectly fine.

I have gotten new transmission fluid and that didn't seem to help.

Have you scanned for codes?

Is it 4cyl engine?

Quick google search

TCM failure is pretty common but I'd scan the codes first cause they aren't cheap.

Yes, it is a 4 cyl engine.

Do you guys know any car service places that specialize in Mazda ? I've googled and seen some other people have issues as well but seems like no one else has that reversing issue.

I'm not the most car-literate person haha. Thanks for the help guys.
