VS Commodore problem

I bought a 5-speed VS Commodore a couple of months ago.About two weeks ago i noticed some excess vibration coming from the gear lever and it slowly got worse, now the car shudders from 1st to 3rd.
ANY IDEAS?GEARBOX?CLUTCH?????????
Any replys would be greatly appreciated!!!!

ur a gay head

hey man yeah my vs does it aswell but only in 1st n second, my mate had one and did the same thing, and it was his clutch, we just put a heavy duty clutch in it n its been sweet since, my clutch is buggered now n it stinks so i will be replacing mine very soon, the clutches in vrs n vs r supost to be pretty shitty so ant heavy duty one would be alot better.

Broken gearbox mount or the centre bearing in the tailshaft, both problems are easily fixed. Most likely both have occured at the same time, as they are both the cause for the other to fail
