5th gear syncro? Grinding.

[Fett]

This one struck me as odd...

I have a WC T5 built by ProMotion, I have less than 10k miles on it. Everything about the tranny is solid, shifts great, no grinding through the gears I use at the track. But a few weeks ago I noticed that if I shift into 5th gear anything above 2500rpms, it grinds going into gear. It goes in fine and doesn't try to kick out, it just grinds. It doesn't do it if I am in lower rpms, just in the higher range.

It just seems strange that the one gear that I rarely use would grind. Any thoughts?

I also have a WC T5 and mine only grinds in 5th. The rest of the gears shift great. I even switch to synchromesh and it did not help. I just shift from 4th to 5th slowly and no grind.

I lived like that for the first 7 years i had my car. there is something wrong, but it's tolerable and you learn to drive around it.
