[/u]

Excellent news Paul

I had the new torque converter fitted last week so I can relax now

Luckily at the same time, the mechanics noticed that a drive shaft was warn out (Rear ball joint?), Too stiff to move by hand so they ordered a new one for me as it's still under warranty, but got sent the wrong part

Should be fix my the end of next week with the correct part.. Fingers crossed

Can only give top marks to my dealer

I too now have the the ‘cattle grid’ noise & vibration on my ’03 4.4 V8 (with 107k miles) and I thought I'd have a go at using my Blackbox Faultmate to see what the torque converter lock-up clutch is up to and it clearly shows that the LUC is unable to maintain a constant slip rate even when the vehicle speed and throttle angle are constant. The current supplied from the transmission ECU to pressure solenoid 4, which supplies hydraulic pressure to the lock-up clutch, is practically constant too yet the engine speed is all over the place.

The faultmate is a nice bit of kit Phil.
I wish I could justify the outlay on one.

Good luck with the work

Are you putting an upgrade TC or original LR?

For me, it's been almost 8 weeks without the range rover.

Had the new torque converter and a new drive shaft, but the vibration is still there

It's getting it's 3rd Gearbox fitted today, last one was only a 6 month old reconditioned box...
They said it may have been fitted incorrectly.. something to do with a valve not opening? Controlling the pressure in the TC I guess.

Fingers crossed for the new box

12 Range Roverless weeks later.. it's fixed

The culprit was the injectors, previous owner had fitted the wrong injectors (incorrect serial no.) new correct set installed, perfect ride.

Driving a range rover for the first time in 3 months makes you appreciate every little inch of it

Wow, you have a new motor.

Glad it's sorted, I presume the cost was covered by somebody else?

I had the opposite, they changed the injectors first, TC last.

Well the word perfect was a little ott

it was under warranty when it went in.. dodged a bullet there

But now I have bad vibration under breaking and continuous vibration at high speed but only in the steering wheel.

I suspected the wheels or rotors are damaged but the power steering doens't seem very powerful

6 months of ownership, it's spent half that in the repair shop

Hello everyone.

I'm new here. Just read through everything, very interesting reading. I have a similar problem on my Vogue - 03 4.4V8. The difference is that the sound and vibrations start at 95km/h (approx. 59mph) and fades away around 115km/h (approx. 72mph). It only appears in 5th gear, auto and manual, especially if you push gently on the throttle so it doesn't gear down to 4th. Any ideas what that could be? Perhaps the torque converter as well?

@ brunofarare

Sounds like wheel balancing, 50 - 65 is the classic speed for this ? You may not get a wobbly steering wheel but you will get vibration/noise. .

I thought so as well before but i have two sets of tires, summer and winter. The summer set is on 19" 255/55 and the winter is on RR Sport 20" 265/50. The sound and vibrations occur on both set of tires. It disappears if i put in N and it comes back when i engage D and gently push the accelerator again (in 5th gear between 59-72mph).

Well that eliminates wheels

Do you get the same vibration at that speed in 4th gear (go Sport or Manual) or even 3rd gear if you dare? This will help to identify whether on the final drive or before it (5th gear specifically) .

Could be worn brake disk and/or sticky caliper

This is a super old thread, but the Vibration at speed that can be felt through the drivers seat / through the steering wheel at 50mph plus and then disappears when you put your foot down hard..

Has anyone ever considered it being the TPMS throwing the wheels totally out of balance?

I am on my 2nd L322 the first being a 3.6 tdV8 and now I have a 5.0 S/C and I have exactly the same issue. Someone from an independent specialist recently suggested they have so many cars coming in with the same issue, but its normally down to TPMS on all the wheels throwing out the balance.
