I was having the same grinding issue going from 5-3 after driving my car hard for a probably 10 minute span and it went away after a few days. After posting on this board, people told me not to go 5-3 and I have been shifting 5-4-3 ever since. However a few weeks ago I took a spin through some back roads driving hard for about 15-20 minutes or so and was shifting all throughout the gears and never skipping a gear. I was trying to rev match as much as possible but I'm not too comfortable doing this at higher speeds yet so some of my shifts were jumping up 2-3k rpms. After my little romp, I was grinding 3rd for the next couple of days. I did some rev matching and I don't think it happened doing that. If I downshifted normally (not rev matching) it would happen every couple of shifts. However, if I was in 4th, pushed the clutch in, went to neutral, released the clutch, and the pushed the clutch in and tried to go to 3rd it would grind everytime. Like I said, this problem went away after a few days.
Does anyone know what this might have been? My assumption is that the hard driving was heating up my gearbox and maybe warping the synchros? And then after a few days they reseat themselves? I don't really know much about transmissions so I might be completely wrong...
