[/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.
