Thread: Disco 3 TDV6 transmission hydraulic noise

just an update on this problem. Car is at the stealer at present and they have identified the high pressure fuel pump as the culprit.

No idea if this is correct but happy to go along with it and see if it cures the problem. Lease company pays for maintenace.

sure hope it does fix it

good luck hope this is the fix, let us know how it go,s

fuel pump did not cure the "noise" Did not think it would but hey lease company paid for it anyway.

Trans has had the $1500 service, filter and pan done. did not cure it either.

Noise is still there. I'm hoping it is not a ongoing major issue. Time will tell.

Have same model same mileage same problem cured yesterday by wheel balance! I had presumed major a drivetrain problem

it has just had new tyres, wheel align and balance ....

noise still there. It is there when car sits still too so not a wheel balance issue

Just wondering if you had an answer to this noise? Mine has just started making a noise that sounds a bit like a toothed belt noise, but seemed to come up at the same time as some transmission faults. Noise is directly proportanal to engine speed for me

Alternator is a big suspect there with the whining sound and trans faults etc Shane. How many km?

Have had it to Australs several times, no problem found each time. Grrr Eventually they did a trans service, flush and new oil. No different. Noise still there.

Also there is what I can only describe as some sort of "resonace" type of noise around 50 - 60 kmh. I am thinking it is some sodrt of diff or tailshaft problem.

Any thoughts?

Peter I'd be thinking about checking either torque converter alternator or even a/c compressor clutch bearing....
