Earlier this year I completed a rebuild of the transmission in my '83 X. Once completed everything worked perfectly. Here is the link to the thread on the rebuild:

So after about 3k miles third gear is starting to grind a bit. I can avoid the grinding if I pause just a bit when shifting into third. So I am thinking I will need to pull the transmission apart once again this winter. Does anyone have any ideas on what could have gone wrong? I replaced third gear, synchro, slider along with some other gear box parts and filled the transmission with Redline MTL. Here is what I am currently thinking:
1) - I did not replace the synchro ring expander pieces but they did not seem worn. Could these pieces cause the snchro to fail early?
2) - Redline has two transmission oils, MTL and MT-90. Was MTL the wrong choice?
3) - Maybe the third gear bushing is causing too much drag preventing third from slowing down while shifting? I inspected all the bushings and did not see any excessive wear. Maybe the bushing is galled or debris is trapped?
4) - Maybe I have installed a poorly made aftermarket synchro ring?
I won't be pulling the transmission apart until the cold weather forces the car off the road (Novemberish), but any ideas on what could be the problem are welcome.
