Guys,

In searching around for a 240Z to race next year, I see some referances to a 'double pinned' transmission. Can someone explain this? Is it the shift forks?

That brings me to another question, are there any other mods that can be, or need to be done for a 240 transmission? Are there 'pro' shops that do rebuild such as Rebello and the like? What is the ballpark for a tranny rebuild? How often do they need rebuilding?

Thanks,
Jeff
