2011 Z06 Manual Transmission
The 2011 Z06 transmission has carbon fiber syncros. Did GM put the same transmission in the 2011 Grand Sport ? Does anybody know ?

I have heard there are problems with the carbon fiber syncros. They work well at first getting rid of the nibbles and grinds when cold, but there is a know problem of "ion exchange" that can occur between carbon fiber and aluminum from the other aluminum parts in the transmission. This will weaken the carbon fiber over time. This is exacerbated with the hot and cold cycles of the transmission and the carbon fiber syncros will become brittle over time and you will end up with very serious nibbles and grinds all the time. I would go with the 09 or 10's.

i dont know why i feel this way, but knowing mine is notchy when cold then fine when warm i cant help but think a different oil might be the solution. clearly it cannot be the syncros per se because they work just fine when warmed up. in fact i would go on to say they work even better when hot.
this tells me it has to do with oil viscosity. and i dont know a lot about what the chemical make up of this type of oil is but i know it is either the same as automatic trans oil or very close to it.
perhaps a synthetic or somthing with different temp range?
i know someone here has reported better shifting with a different oil. but i cannot locate that thread.

Makes total sense

I did notice much better cold performance with the Amsoil but I do still get a touch of nibble when I first start out but it is usually gone within a couple of minutes.

It's probably listed somewhere here on the forum, but what causes the nibbles? I thought it was me just getting used to the clutch, but apparently it's not. Thanks.
