No, traction control is standard to all v6 omegas whether they have a lsd or not.

I thought that traction control on later Omegas simulated LSDs. Is this not the case?

It's a bit different, the next best thing to LSD I suppose but not really the same.  Traction control simply applies the brake to a spinning wheel (or rather to a wheel that the computer judges is spinning too much). Traction control therefore reduces the power to the spinning wheel.  LSD re-distributes the power to the other wheel.    LSD is more expensive.  All petrol heads will prefer LSD I'm sure but to be honest the end result is quite similar.  You can of course have both.

What if you put some resistance against a moving wheel (carefully) e.g. hold a block of wood to the tyre?  I would expect that wheel to stop and the other start but if both wheels continue that's limited slip I would think.

Sorry for the thread hi-jaking on this 

I jaked one side of the omega with supossed lsd fitted and selected first gear..ever so carefully/slowly with aid of someone watching let clutch up and the car tried pulling off with only one wheel on the ground... = lsd so it would seem?
also got both wheels to lock in a spin in a straight line but not in a circle.. il take out the diff some evening and look at the diff id plate, into it and see about getting it shimed.

yes thats the quickest way to test it

I'm sure you did this but just a note for anyone else make sure traction control is switched off for either test.

Is the td chipped? If not get it chipped and get the lsd shimmed, a chipped td is fit to lock a good lsd. All lsds are 3.7 or 3.9 ratio, this will leave a td worse on fuel, a lsd  can be built with the a td gearing , I have done a few of them

only seen this now ,, yes it is chipped but has 155k of not so careful driving (the most recent 45k has been shockingly hard) this building craic sounds interesting tell me more
