the other day while driving I had a really, really hard time getting into 6th gear. I kept trying until i decided to force it in a bit harder. It went in without making any particular noises or grinding so it felt fine. Going into 6th gear hasn't been a problem since then and and ive never had a problem before that. Should i bring it into the dealership of should i forget about it?

Mild syncro problem wouldnt sweat it.Dont start to worry until the bearing start to whine.
