do i have a bad Fork? or synchro?
Okay, the symptom goes something like this... I had problem putting it in 3rd gear... it'd pop out randomly... and sometimes it'd go in, and when i accelerate heavily it'd pop out...
I thought it was just the loose bushing i had, so i custom made one out of metal, (turned it down to the size, drill a hole in the middle and stick a bolt through with lots of grease)
so i tried this, i stuck it in 3rd to start off and let the clutch out slowly, just to see what happens... it immediately pops out and makes grinding noise, (like a regular grinder... or like dentist's tool thing)
I'm just wondering... did my short shifter screw up the synchro? because i was reading somewhere here that short shifter, no matter how good... over time, it messes up the synchro. or is this something like a bad fork?
I'm guessing it's a lot easier to just replace the transmission lol, i've done it on a DSM once... time for me to take another weekend off i guess lol, but i just wanted to know, so i prevent it from happening nex ttime, what the cause of this could be

I've seen some people say a short shifter will mess up the synchros and some people say it won't. I'd say it won't be the shifter itself the messes up synchros, but the fact that you're shifting faster and possibly not giving the synchros time to catch up and that is what ruins them.
I'm no "expert" though... The short shifter merely shortens the length of the shift rod, not the change rod...

honestly.. I used to believe that short shifters would cause damage to your synchros.. but thats just because I read it online. After we learned tranmission in school and took them apart and learned how they work I no longer really believe this (i assume if you shift REALLY fast it may cause a quick grind) but that would be over a long-term of abuse.
It is not your clutch fork.. it's most likely your synchro assembly unforunately... but it soudns like you may have a hacked up shifter, so it may be the cuprit but I highly doubt it if its only 3rd gear

Wikipedia says
"Thanks to this mechanism, before the teeth can engage, a frictional contact is made between "synchro cones" which brings the selector and gear to the same speed. Moreover, until synchronization occurs, the teeth are prevented from making contact, because further motion of the selector is prevented by a blocker (or "baulk") ring."
It's weird because i think it has to do something with this.. when i stick it into 3rd... like it doesn't feel like it's got that "click" feel to it... when the tranny is cold i get 3rd gear a lot more often than when it is warm.... and if i force it in and hold it there with all my force, it grinds for a split second but gear engages...
any suggestion?
