Thread: A Curly One D4 Major Gearbox Fault

Start with having the engine and gearbox fault codes read. If the codes haven't been cleared for some time then possibly best to clear them then interrogate them after the next fault occurs.

Hi. How many kms and have you had auto serviced? Despite LR claims of sealed for life transmission they now suggest replacing fluid at 100,000 km or sooner if you tow or do lots of off road. I know from costly experience that it can lead to a rebuild if not serviced. Service casts about $900.

That claim is a furfy and LR does not claim it is sealed for life - the service requirements are listed in the service schedule and while it is extended it is not sealed for life.

But you are correct, the gearbox oil should be replaced at less than 100,000km intervals.

I agree Garry however ZF themselves have conflicting information published. See the attached sheet from ZF which states "lifetime fill", whatever a lifetime is.....

Certainly does not help.

So if I mostly use my D4 to tow, and it's done 185,000 kms, you guys would recommend I get the transmission oil changed, even if there's no obvious sign of any issues?
I'm confused about this - my dealer told me don't bother, then a newer closer dealer told me I should do it (but they charge exorbitant amounts for labour, and told me it would be $1500 assuming they found no faults and changed the fluid).
I'm also reading that I should change my oil every 10,000 kms if I tow regularly?
I'm starting to think I've really let my poor car down.

Yes defiinitely get the fluid changed - not sure of the 8 speed but if a 6 speed also get the plastic sump changed to the metal one and a new filter.

All up with a megaflush of LG6 oil should about $900 at a good transmission place.

If an 8 speed - not sure of the metal sump but get the fluid and filter changed.

Here is an extract from a service manual you might find interesting

The maintenance items listed, are those recommended for vehicles operating under normal driving,
road and climatic conditions. More frequent attention may be necessary if the vehicle is subject to
stop/start operation, extremes of temperature, dusty conditions, off road driving or frequent towing
of trailers.

I do a bit of off road driving and I still get it serviced every 10K and the transmission 80K
