2006 Sport. 89,000 on the clock. Just developed a very noticeable judder at around 3,500 revs??! Feels like an engine problem, I am sure wheels are balanced correctly - the feeling is not coming through the steering wheel, the whole car judders - any thoughts Andrew Kennedy

Sounds like a prop shaft bearing to me! Current: 2010 RRS 3.6 TDV8 HSE

Transmission failure. Sell it quickly..

prop shaft bearing would be my guess also. Had mine replaced last year - the symptoms were juddering around 70mph or thereabouts.

Propshaft bearing Revs related?

Unless it's always at the same speed, I would say not.
Have you tried all permutations, like gear hold in all gears to 3500rpm to make sure? 2011 MY D4 HSE

Yes! The centre bearing especially has a rubber mounting and if it is damaged it won’t support the shaft properly and the faster you go the greater the vibration. Current: 2010 RRS 3.6 TDV8 HSE

So to clarify..
Revving the engine stationary to 3500rpm has no effect on a propshaft bearing.
Road speed does.
The prop can be inspected underneath if you know what you are looking at and for. 2011 MY D4 HSE

I agree with Bardley. Prop bearing issues would be speed related ie. rotation of the prop and not engine revs related.

Andrew, do you experience the problem at 3500rpm no matter what gear you are in/speed you are doing? Kev

Thanks for the input!!! Yes the juddering occurs at around 3,500 revs which ever gear its in. Andrew Kennedy

Torque converter. Stick a tube of Dr Tranny in the transmission and that will fix it.

That is certainly consistent with the transmission problem I experienced (lock up clutch slipping). Cost me about £1600 for a repair. Some of the best money I've spent on the car - smooth gear-changes all the way.

Just one tube. It's American so it's in ounces. The fools.
It worked on my X5 and a mechanic friend uses it a lot when servicing high mileage transmissions.
To be honest you may cure the judder with a double trans fluid change.

Torque converter issues can feel like driving across a cattle grid for want of a better description,, if your on 89k miles a megaflush is definitely on the cards,, get a couple of tubes of Dr tranny added when this is done and a gearbox reset and see how it goes. 2010 RRS, TDV8

Megaflush it (not the Land Rover double change which is fairly ineffective). It really needs to be flushed at 60k miles to be effective at improving the lifespan of the box.

To be honest, once the TC is juddering, anything you do (other than replacing the clutch) is just hiding the problem. It's not a cure. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
