Hey everyone, I noticed today that when shifting into 3rd gear I get some grinding sound, still goes into to gear and works good, but the grindding is worrisome. This only happens when I shift past 4000 rpm. Is it my 3rd gear that's starting to bugger, or somethingelse? I've Changed my gear oil just recently and my car is mostly stock. Any responce would be helpfull on what to do.
