Hi,
I have ATS 4.46 and ACT flywheel. When I try to shift from 2nd to 3nd, at rev limiter (but also at low rev), my gear grind. It happens particularly exiting from a bend. I don't know if in the transition gear train moves and then when I try to shift to 3nd, my gear grind... sometimes happen from 3nd to 4nd too... is it a syncro problem? What could be the solution.

Do you know if synchronizers, for EU MY06 and USA MY06 are the same?

thanks

 

nothing?

 

Do you know if synchro 1-2 and 3-4 of an Ap2 fit on AP1?

Thanks

 

How many miles are on your s2k? I'm assuming it's a 2006 based on your questions? How recently was the fluid changed? Did this problem start shortly after installing the aftermarket flywheel/clutch? Is the problem equally bad regardless of the transmission temperature? We need more information here...

 

maybe ur shifting to fast and the clutch delay valve is kicking in.

 

Hi,
I change my question. Do USA AP2 (F22C) synchro (1-2 and 3-4 gear) fit USA AP1 (F20C) ones?
As I know, gear update from USA AP1 to AP2 interested carbon synchro, secondary shaft (which reduced gear from 1-4 by -4%) and gear ratio of 5th and 6th gear. Am I correct?

thanks
