In it's albeit limited defence, said box has done more miles than your last two Omegas put together ::)

Before...


After...


This gives the lever a solid foundation, as the front end of the lever mounting plate is bolted to the gearbox, the rubber one being attached to a bracket above the propshaft :y

Fair to note that NVH is slightly increased, but given the suspension bushing and tyre size/pressures I am using, this becomes kind of irrelevant  ::)

Is there a diagram any where so I can see how it all connects?

My friend said he used Dexron II ATF in his Omega manual gearbox with no apparent problems. Is this safe to use?

I have 5 Liters of Fuchs TITAN ATF 3000 Multipurpose Dexron II ATF. Is this safe to do a complete oil change on my manual gearbox?


Is this the same stuff to put into a Auto gearbox?

Thanks

Same problem on son Ben's 2.2 Bleedling  achieved nothing. Slave cylinder is concentric, isn't it? So right in the middle of the gearbox, can only be changed with gearbox out of car. I recall in a discussion thread some while ago they were claimed to be bulletproof. Thanks for g/b oil level suggestion, Chris; I will check that when I have the car in for MOT soon.

Hmm. My first (and so far only) manual Omega had a slave and thrust bearing fail. Yes it's concentric, and yes it's a box off job to change. And if you ever have to change one, open the box and inspect the 'new' one before you leave the dealers. I failed to do that, and when I went to fit it found a second hand faulty one in the box.

What was your symptoms when the slave failed?

What was the symptoms when the bearing was failing and then failed?

Thanks

It went 'all of a sudden' - no symptoms prior to failure that I can remember.

Once failed it was a 20 minute/10 mile drive with no clutch from home to my workshop. Cursing every doddery old fool stopping unnecessarily at give way's and roundabouts.  A bit 'graunchy' at times but the synchro survived.

Slave is FUBAR too. Still got the old one in the shed somewhere, will try and dig it out to see what's wrong with it. From memory, the skirt is all split.

Had a look at the mounting rubbers and they look fine to me for what I can see. The photos are below. What do you think?

Top pick is the Gearbox/Engine rear mounting... looks fine... a new one might be firmer due to a lack of aging, but that looks intact and therefore perfectly serviceable  :y

They can degrade quite quickly if exposed to alot of oil. Like this...
:-[

Second pic is the thing I replaced with the bolt/washer combo... mine was unbroken, but very squishy, making the gear changing feel rather vague :D

If the slave fails then you won`t be able to engage gears and your foot will go to the floor without much resistence, I had one fail on my Senator but it was gradual, I managed to get from Catterick garrison to Leeds before it went completely.
