I own a Hyndai Elantra Coupe (2013 or 2014, can't remember), and for a time I was changing gears downwards in order to brake (the context is we were taught, in driving school, that you can do this if brakes fail. So I was practicing),
Some time later, it started making a loud "click" noise whenever I changed gears. Specifically, whenever I release the clutch and a gear is selected (meaning the noise doesn't happen on Neutral).
I'm wondering if this noise issue is common enough so that it can be diagnosed by merely describing it, and if so, what's wrong with the transmission?
