I just took apart my gsr trans., found 3/4 synchro hub had small score marks from inside of sleeve. Is this major or minor, should I replace synchro hub and sleeve. Synchros look good but looking for some opinions. Thanks

 

My 3/4 was pretty gouged when I pulledapart my tranny, decided it would be stupid to not replace it while I was there, ended up costing around $180 shipped for the parts so it wasnt that bad.

 

Yes. You should also inspect the spring springs (the rings pressed onto the synchro ring). If you see any gouging or scuffing on the rings, they should be replaced.

They are included with the synchro set.
