5th gear "crunching" with shift

Alchemy

I really need to get my Z looked at. I still get an occasional grind in 5th. I worry about the dealer being able to replicate the problem as it doesnt always do it. How long did it take your dealer to actually diagnose the prob?

They drove it, then called to confirm the problem the same day - brand new transmission installed three days later.

I tested the new gearbox, and the problem is now COMPLETELY gone. I can even snap from 3rd to 5th without the slightest grind. Nice service, good dealer.

It would grind whenever I'd shift into 5th from 4th if I tried too shift quickly. It would ALWAYS grind from 2nd to 5th, no matter how slowly I tried it.

Problem completely gone now with new gearbox; even 2nd to 5th works fine (it takes ever-so-slightly longer than 4 to 5, but still amazing compared to the old shift).

Baker Jackson is the dealer here. They have a "performance tech" that looked at the car and figured out the problem. Didn't even have to drive it for them and no one challenged the diagnosis. Maybe this problem is well-known now; probably appeared in enough 09's they know the score.
