Gear selection problem

Post by ZOOK60 »

Last week i was just about to get off the freeway and i had probs selecting gears when changing down. I had to rev match the enging to get it to pop into gear. When i got home the master cylinder was below min level but not totally empty.

I have toped it up and blead the system but it hasnt really done to much.
When i first start it it seams to shift like normal but after about 5 gear changes it starts to get hard to change you have to hold it against the gate and rev the engine then it pops in.

It makes some noise when the clutch is pushed in too. I replaced the slave cylinder today due to it leaking but it hasnt changed anything. It holds fluid now but is hard to find gears. I also changes the oil in the gearbox.

Is it in need of a new clutch or is the gearbox the prob?

Sounds like your clutch isn't disengaging properly.
And that's about all I can tell you (I'll leave it for the more experienced guys - but you're better off posting this in the GMH section)

try pumping the clutch and then try a change.

did you bleed your slave cylinder after you topped the master up?

Could be a small split in the line. Had this on my skyline just had to get a new line and was all good.

I normally just crack the bleeder and let it gravity bleed until all the bubbles are out

my vit-94 cable system
at the moment clutch feels hard and cant select gears, then at times very soft and selects properly... i have to change the clutch soon...
prob same problem as you, there is probably mud stopping the clutch disengaging or the release bearing is seizing up... i dont know yet, will know in the next few weeks when i have time to pull mine appart...
