I've got my gearbox opened, how bad is it?

[El-RGB]

Hello all,

I'm undergoing a new clutch installation from JUBU and a LSD fitting on. While I'm at it, I have the shop opened up the gearbox to have an inspection since I can't shift into 3rd after a few laps on the track.

I was guessing the one or two synchros went bad, to my surprise, the actual gear looks worn!

If anyone has the the experience can help to tell how bad is it? Is it bad enough to be salvaged? Thanks.

Cheers,

Frank

It's alot of effort to get to it and not replace it...

You are absolutely right Dave! Every gearbox work requires a lot of labor time to get to it.

However, sadly every the part order take a long international shipping to get to me. I'm still debating if I can stick with this condition for a few more track sessions till I get to the point for another overhaul upgrades. Cheers!

To further investigating the cause of this. It is weird that the gear went out before the synchro does.

I can't shift into 3rd gear only after a few laps when the car got hot on track. I suspected that about 50 mins track sessions with constantly trying to force into 3rd and that worn out the gear.

I think it was due to a bad clutch travel which being too short for disengagement, ultimately causing the 3rd gear a bad alignment. The 4th is a bit worn too, but not as bad.

I'm worn on no.1, no.2 and no. 24 shown in the diagram.
