hey guys title says it all... i have a 2015 tlx
And it just recently started making this funny sound.. when idling and or when going 10mph or so .. has oil I done all the regular maintenance... i took it to dealer and they said if I didn't have a check engine light then its probably nothing.. i don't believe that crap.. this noise for sure sounds bad! Will add a video of it. Anything will help. I just need to know if this may be a transmission issue or what.

I would bring it back, or to another dealer. Powertrain warranty is 6 year 70K. They should take a look at it. Have them take a tech with you on a short test drive, thats what my old dealer I used to work at would do.
