I have a grind going into 5th gear right now, and every so often going into 3rd. It actually grinds worse if I skip a gear, like 3rd to 5th is bad. I have been meaning to take it in to the shop, just don't want to lose my car, lol.

 

Im getting this now, I think i'll call Nissan after I check to make sure I can reproduce it for them.

 

I have the 3rd gear grind, but only when engine are cold..(within 5 min). After that, it shift ok. I know it will be hard to duplicate this problem when I drop off the car to the dealer, guess I will have to wait until it grinds all the times..
