ok so its been going on for like 2 weeks now, but everytime i throw it to 3rd gear, it grinds. this only happens when i do it kinda fast or hard, it wont happen if i do it slow.
what do you guys think the problem is, and how much would it cost... is it hard to fix?

 

have you noticed when you shift quickly, if your pushin the clutch as far in as when you do it slowly? that was happening to me when i swiched my clutch and had to get used to the new bumpstop

 

no, i will hold the clutch all the way in, sit there and pass the shifter from 2nd to third to forth, to third, and everytime i go from anygear to third, never even releasing the clutch, it will grind everytime... when i do it fast or hard that is

 

syncro probably

 

yeah, someone else had a similar problem, except his would grind whenever he shifted into 3rd. here's the thread.

you should be still under warranty, so if the dealership decides the syncro is bad, they'll replace your transmission at no cost to you.
by the way, mine grinds when i try to shift into 3rd at high rpms, but i just take that to mean that i'm driving the car too hard.

 

well, i have a short shifter, and pulley set, so i dont know if they will say that is that cause of it....

 

i doubt it. theres been a few people with the same problem as you and they all got new transmissions.

 

yeah, my 3rd gear grinded a lot too but it will disappear once the car is warmed up then im able to shift hard again. it's the synchros wearing out.
