I have noticed that sometimes when I shift, I can here a slight grinding noise. Could this be worn syncros, or maybe it just needs the oil changed? I dont know? I happens quite frequently.

 

If you rev it at high rpm(4000rpm) and shift it into gear then its usually the syncro.

 

so whats the best way to replace ure syncro's?

 

4 things possible, oil, tranny mounts, synchro's, shifter fork(s).

 

how about when you are just moving off in first or second gear and not giving the car any gas. i think it's the throw out bearing but what do you guys think?

 

Throw out bearing normally squeaks or hums. It makes a constant noise that should vary depending on if you have the cluch in or out. My guess is either tranny oil(which should be really cheap to change just a few bucks if you do it yourself) or syncros. If it is the syncros just look for a good used tranny on e-bay or something. They run abou 200 bucks. I got mine for 150 plus 80 shipping and replaced it in 1 afternoon.

 

I don't think tranny/motor mounts will give you a grinding noise. When mine were worn I would get a click/clunk noise when accelerating or decelrating/stopping. The engine would wobble back and forth depending on strain.

 

Your suppose to use motor oil if your car is a standard. Use tranny oil if ur car is an auto.

 

grinding is most likely a syncro & or gear problem ----either way its internal ----the only thing u might want to try --is change the gear oil & try synthetic gear oil --maybe u will get lucky

 

Well, I changed the oil last weekend. I put Amsoil 10W40 in it. There was very little traces of metal shavings in the old oil. I noticed that the old oil in it smelled alot like gearoil. Im not sure if the pervious owner ever changed it or what. Anyway, it seemed to shift a little better for the following next three days after I changed it. Now it shifts great! Alot smoother, and it dosn't grind at all anymore! I guess I did get lucky? Thanks for the post guys!
