Thread: D4 3.0 SDV6 catastrophic failure

Do not argue with anything you said. LR just failed to put a drain plug and cap to refill of course Never see or heard of a LR part to fix this as well. I may be wrong of course

Sealed for life is utter BS. Transmission does have a fill plug.
Replace plastic pan with steel asap (comes with a drain plug).

Fit new filter and full flush with new fluid every 40-50k kms. Rebuild valve body at 150-200k kms and you will have a bullet proof transmission for a long time.

Both of mine have or had a steel pan fitted. The first one a bit late and it cost me a gear box. Excuse me if I was unclear. LR should have put that not the sealed bit with no plug Current D3 gear box is great as it can have gear oil drained and replaced as needed as I paid for and fitted the part to allow me to do it. Stock LR and that cannot happen as far as I know. Fully agree "Sealed for life" is utter BS

Part of the rationale I’m sure is fact every day driver cars in hard winter UK / Europe are lucky to exist after 10 years when you see the rust ball they turn into.

We are very lucky here for nuts to still undo after 5 years let alone 10.

Navy Diver I think you are a bit confused - the OEM plastic gearbox sump has a drain plug and the gearbox has a filler plug so with the standard setup there is not reason oil cannot be changed - is an issue with the filter.

For the OP - sorry for the distraction.

I would go to the Disco3Uk and the RRSUK sites and search rebuilding these engines - the consensus is the repro parts are not of good quality and reliability is in question - now I dont personally know so do your own research - countering that some repro engines have been fitted here and they seem to be working fine.

So - research before committing.

I get my son to start it and there's a wild old bang bang bang in the engine. Shut it off straight away and wait for NRMA to attend though I know in my heart what has happened. No warning signs, no indications on the dash, oil level is fine and no coolant loss or overheating.

What say ye wise people?

What year is it?

I thought that it was the 2.7 litre that had the random engine failure issues and that the 3.0 litre was OK?

Nope, whatever the learnings from the 2.7 failures they seemed to resolve later were un-applied to the 3.0 just as the 2.7 was dropped.
