    Default manual vx problem

    gday, Today noticed that in my s pack vx manual that it was becoming hard to put into gear or go into any gear for that matter. It wouldent crunch or anything but when trying to chnage gears or going from netural to 1st for example it would be extremly hard to put into geat it just wouldent slip in like it normally does . What could be the problem?

    its got a fairly new clutch kit in it. only about 2000kms old. My clutch fluid is black and assuming its the orignal fluid from factory would this have any effect on anything?

    ok Iv now know that its my clutch that is always staying abit engauged even when the clutch is put all the way to the floor this is why it wont select gears properly. This is very apparent when the car is in 1st gear with clutch in it creep forwald and also when driving if I put my foot on the clutch the engine revs dont drop back to idle they just stay the same. I'v bled my clutch line and the probelm is still there. I think I may have bent the shift fork,or my master/slave cylinder is not functioning properly anyway way to check this?, I do have a heavy duty clutch in it and have abused it afew times. anyhelp asap would be great becuase atm im going to be pulling the gearbox out tomrow night need my car for work on monday driviable

    It is possible to adjust the position of the clutch pedal from inside the car. Try this as my clutch started slipping and I discovered that the clutch pedal needed to be adjusted.

    the car shifts gears when the engine is off so that pretty much rules out the gearbox being stuffed, The car has done 110,00kms so not much. I will admit I do abuse it from time to time but nothing to the extreme. Been doing some reaserch on google and have pretty much pinpointed it to either being a bent shift fork or stuffed master/slave cylinder. Anyway know how I can test to see if it is acually my slave/master cylinder? My car has has a sligh squeak when the clutch pedal is pushed down ever since I brough it. Also the clutch fluid level is not dropping at all if this helps. probly should have also mentioned that iv had a slightly sticky clutch pedal on a few occasions also
    thankyou

    How do you do this? My bite point is really high and I'd like to lower it slightly.

    I think I have the same problem, though not as bad as yours.
    I have recently replaced my clutch master and slave cylinders, so it rules out that for me and I'd say you as well. Remember the principle of hydraulics - they can not be compressed. Metals can be bent, so I'd say that it could well be a bent shift fork.

    There is a threaded rod that screws into the plunger for the master cylinder from the clutch pedal. There is a lock nut that needs to be loosened and the plunger nut can be rotated to move the clutch pedal in and out. Make sure to tighten the lock nut as the pedal will eventually creep up again.
    There should be no need to take the rod off the clutch pedal but if it needs to be done the clip needs to be prised sideways after lifting the catch. You will understand once you get it off and it can be a bugger if you have never done it before.

    ok today I fitted a new slave cylinder, To no sucess, My old man adjusted the threaded rod that connects to the master cylinder that your talking about which at least allows me to now chnage gears smothly but still the problem is there slightly. Tomrorow I will be getting a new clutch master cylinder to see if this foxes the problem. I have got a new clutch fork here and boy do they look strong I really doubt that I bent my one.

    I went gand got a new master cylinder today as I thought it could be it, fitted it all up still same problem. So me and my old man took out the gearbox to find that the thrust bearing had come out of its slot, Why this happened we are not too sure anyone had this happen before? Also my pressure plate bolts were all loose so for anyone installing a new clutch please loctite EVERYTHING. Fitted it all back and now the clutch is perfect. Me and the old man had the gearbox in and out in under 3 hours so that was pretty good

    G'day simon I.ve got a vt ss with exactly the same problem.I have a six speed box.It sounds like the shift rod in the box might be bent or possibly the bearing.I'm kind to my gearbox and this has happened.I'm putting up with mine for now but eventually i'll have to get the box pulled out and repaired.I thought it was the clutch not disengaging fully.I wish it was would be a lot cheaper.Hope this helps cheers
