Try upgrading the engine & auto trans software to the latest spec, which, in turn will also reset the adaptions.
I have cured a few like this, both the surging & the erratic gear change

Update 09/11/11
Came back from the transmissions specialist yesterday; They are adamant that this is not the 'Juddering' issue and they're well versed with the issue as they've repaired several LR D3s with the problem. At this time, they are siting software problems causing a miscommunication as to when the box should upshift.
Car is now booked in for a full service and assessment at Stratstone Land Rover and I will post a follow up of the results next week

Hi All,
I've read about the dreaded Judder, i don't have any problems at the moment with the Gearbox just wondering if you can prevent the contamination? Is it from a leaking Radiator and if so would it not be worth changing for a new one bearing in mind the cost of a Gearbox??

Yep, from a leaking radiator.
Do-able yourself if you can wield the spanners ok. No great issues, but just make sure you have spanners or some other tool for getting the viscous fan off.
When you do it, it is also worth either replacing the intercooler or allowing some time to give it a good clean - as it comes out sooooooooooooooo much easier with the rad. 
I have written a guide to replacing the rad - but you won't find it on here. Can be found elsewhere though.  Mark.

Thanks Angelfire
Think i've got an idea where to look....
How can a leaking Rad cause it though? Thought these things went through rivers! Does it corrode overtime a seal/gasket?

Well after an incredible amount of fannying about and money spent this week including:-
- a trip to the gearbox specialist who said that it wasn't juddering at all and there was nothing wrong but then reverted to saying that it would be a software issue if anything
- a trip to the local dealer for a full LR service and inspection which came back with no faults bar a brake light bulb
and finally a trip to the local, well respected independent LR/RR Specialist today who has informed us that he had the exact car in a couple of months back (just before we bought it) for this issue which they were unable to identify or correct in the given time by the previous owner, I'm left completely fed up.
None of the three above were "aware" of this issue and certainly not interested in fixing it even if they could, with this in mind, could anyone on here recommend me someone who is both capable of doing so and knowledgable about this problem. I don't want to be someone's guinea pig and would rather have somebody respectable take a look at it.
On a particularly sore note, since the problems started and we have dug around the internet, I have found posts made by the previous owner detailing the issue we're now having only a matter of days before we bought the car. The problem didn't show up on the test drive which has leads me to believe that something was done to temporarily 'fix' it for sale!!!

| autogear box contamination . |

Would the forum recommend a radiator change at the 105,000 mile service, ie cam belt changing to prevent or delay contamination

Finally resolved, blanked off the EGR valves, now runs perfectly and achieving 28-30mpg on a decent drive. Wasn't to do with the Gearbox at all, it was power delivery effectively confusing the gearbox as to when it should change gear

Sorry, not seen this until just 
The gearbox oil cooler (And heater effectively) is sandwiched on the side of the coolant radiator (Looking from the front of the car, on the right) This means that there is a water on one radiator and oil on the other, with a "metal plate" between the two - I'm guessing it would have some sort of corrigating to increase the surface area for heat transfer. It is either this plate or the seals between them that fail - and it can be a very, very small hole/perforation between the two fluids that allows water/glycol to enter the gearbox oil system and screws it up. Mark.

If the Auto is getting contaminated from the Radiator coolant, Who has added an External Cooler & what's the process.
This seems like an easy fix to a very expensive repair that's un-necessary if it can be avoided.
Has anyone actually tried this before the disaster ?

I have a D3 from 09 and 2 ½ years and has 75000 km.
I have the same problem, the gearbox does not change and sometimes stays at 2 and continues to push pause for 2 seconds.
I asked the foreman on the phone this morning the issue of EGR'sy says that if they were stiff appear an error message and he checked last week in the REVISION.
What it has done is update the software on the gearbox and has no loss of torque at low rpm. That is fine.
I apologize for my English but I can not speak it. I only speak French and Spanish

What a wonderful resource this forum is. 
Thanks to the hints and tips here I was pointed in the right direction of needing to change the auto gearbox oil early in my HSE.
This fixed the following:
Hunting of revs on cruise control
Juddering / vibration which was much worse under heavy towing load when accelerating through 2000 rpm at around 30mph. This has been a pain for a very long time. Not very noticeable solo - until the paranoia set in!
Both issues fixed by a gearbox oil change at 83000 miles thanks to Graham Bell at Bell Automotive, Queensferry, North Wales. ---
