Gearbox Making Wired Noise When Shifting Up

[kma]

I just got my skyline. Dont know too much about them but i noticed my gear box making a bit of crunching/shuddering (not too bad but you can feel it) feel goin into second. Its only when it reved above 3k and if i leave it in neutal for a bit then shift it seems to be fine. Its only when you are shifting up, shifting down is fine

Anyway any advice is much appreciated.

maybe the 2nd gear syncro? I had that in my corolla and thats what the diagnosis was.

dunno if that helps.

I've done a bit of research. It may well be the synchro

Any idea how much to fix? is it a big job?

Cheers,

anyone?

don't know where you are but... competition gearboxes in Croydon, or Award in Seven Hills,

some thing around $500-=$1000 syncros, bearings etc,

ring one of them for more of an idea,

Gearbox fluid change might solve the problem depending on the current state of the fluid. Do you have a short shifter installed?
