    the only thing i can remember on the f23 gearbox is there is a modified 2nd gear syncro that vauxhall did and some of them were still to get second when cold, they did a technical bulletin about it which should be on tis 2000 if any one has a copy! hope this helps!

    Sounds like all you need is a new synchro. I managed to snap 2nd synchro in my F17 box on my corsa, and snap the linkage.

    My 3rd gear synchro isnt to clever, after a brand new clutch and put clutch to floor and itll grind into 3rd coming down from 4th at high revs haha.

    ye where could i get new synchros?
    some1 must sell them lol. i can get it into 2nd with no crunches lol i can even use 2nd to slow down but soon as i put any load on it wit accelerator it jumps out lol.
    is the m32 the box out of the vxr? is that a straight swap or is there alot o work involved?
