G5M-R Transmission Synchro Rings

Hi all,

I'm currently in a bit of strife with the manual transmission in my Astina.

1989 Mazda 323 Astina SP BG Hatchback 1.8 16V DOHC

G series transmission

The 5th gear synchro ring has broken and I have been unsuccessful in locating a replacement, or even a replacement transmission entirely if I have to.

Just completed an almost full rebuild on the car (literally everything), so I can't really back out and give up now.

I believe the transmission is a G5M-R Transmission.

Does anyone know where I can obtain internal transmission parts for this car? I don't care if it's internationally...however I am located in ACT, Australia.

Hoping someone has any suggestions on the matter.

GP.

Mazda should be able to sell you one, but they'll probably quote you 6 weeks +

Otherwise a synchro from a BA (BA11P1) should work.

if it has a 76kw bp (or B8) engine, then it isn't the dohc version. so it wont have a g series gearbox in it. it will have a f series gearbox in it.

I think this was in error. I believe it's closer to 96kw and its the Astina SP 1989 DOHC.

I have a G series transmission but haven't been able to find a 5th gear set or just the sync ring alone as of yet.
