synchros shot?

[92protuner]

I think my Synch rings are shot every time i try to shift to second and sometimes forth it grinds for a short second, just replaced clutch ...anyone know where i can buy some replacements...and possably comments on instalation(if anyone has done this)?

haha i feel you bro. I have the same problem. I got a 95 Protege and going into second gear it grinds like hell. I'm changing the transmission, the clutch and grinding the flywheel down. I hope that'll solve my problem. If thats the case it may be the same for you.

have you bled the clutch slave cylinder? If it's got air in it then it may not be disengaging the clutch 100% between shifts... it only takes 5 minutes to bleed so i'd do that before replacing syncros.

Yes blead slave before putting in new clutch also new gear oil and resurfacing of the flywheel.....the shift still barks though

I say if your replacing syncro's you might as well do a rebuild (check gear clearances get new syncro's and new bearings(upgraded ones if possible) might as well do it all in one shot)

Also be aware that gear oil with sulphur will wreck the syncros (or so I've heard) since Mazda used copper alloys for them. Use something like Redline or Royal Purple.
