I've had my FN2 for around 6 months now and have done approx 13000km.
In the first 5000km I had the third gear pop out here and there and it felt as if it never went right in sometimes. 2/3/4 gears tended to be a notchy at high revs when downshifting and upshifting.
from 5000km-12000km third gear never popped out but it has been notchy on downshifts only, upshifts were beautiful and slotted in fine.
and from 12000km, I had fitted a Honda OEM Limited Slip Diff into the gearbox, had the bearings changed, new oil and now the gearbox is fine doing anything, high/low rev up/down shift, everything slots in beautifully, no notchyness at all amazingly. It's great and I can turn even more aggressively and there isn't so much understeer now as well. Don't know why a
LSD wasn't made standard.
