HELP !!! Clunk At 4th Gear !!!
 
Hey guys

I have jus bought my 01 Bug Eye rexy about 2 weeks ago.

I have noticed that if I change from 3rd to 4th at about 60~65Ks, it shifts fine.

But if I shift up to 4th at about 70k~ 80kss, the gears just clunks, like gears

grinding. Is this normal cos I change up at such a high speed or is it time for

me 2 change my trannie oil?

Cheers Guys

Sounds like the sychro maybe worn....

Try changing the gearbox oil redline shockroof that should/may quieten it down....

I am very new to this scene, what is a sychro? Can it be fixed?

My service is due next month, will probably change it then.

Synchromesh is the type of gear selecting used by the gearbox as opposed to a dog engagement setup. It can be replaced, not so much as 'fixed'.

I would try some new gearbox oil and see how you get on either way your box is worn just not out of the game just yet...

Yea haha replace, thats what I mean. Yea I am gonna try changing the oil first.
Is it worth it to replace the synchro or shud I jus start savin up for a new box?

How much would it be to be replaced and how much would a new box cost?

Thanks guys

Id be fairly hesitant to change the oil if its bad. Redline is worth about $200-300 for a refill of it not including labour. if its still rooted, you have wasted about $300. Doesnt seem very resourceful

How hard are you shifting when it clunks?......Ripping it in or slow shifting?

Tecnique issue?

sleepy1386 09-09-2009 05:31 PM

Jus slow shifting!!! I thought it was me not puttin the clutch in completely but even wif me puttin in all in, it still clunks at 70ish ks

what type of clutch is it?
it might just be the clutch clamping down
