Is the 6 speed gearbox in the 2006 facelift Range Rover still likely to suffer at the 100k (ish) mile mark, or was it improved and made stronger??

Thanks.

think you might struggle to find a decent sample size of 100K mile old 4 year old cars to form an opinion on that one ...especially petrol engined ones ...you dont hear of many people doing 20-30K miles a year in a V8 petrol Range

the gearbox is different though, as is the whole engine with the change from BMW to Jag derived powerplant, so one would hope its better cheers

The 5 speed is not likely to fail at 100K if it has been serviced as per the manufacturers recommendations!
It's certainly one of the better gearboxes ZF have produced. This is reflected in that it finds itself in most large luxury cars (VW, BMW, Audi, Jag, RR).

The 6 speed is almost identical to the 5 speed except slightly longer internals to accommodate the extra gear, and obviously a re-worked ecu. If you leave the oil in a 6 speed for 100K then you will have exactly the same problems.

Wait a minute - are we talking petrol or diesel gearboxes?

In which case one is ZF the other is GM until the facelift then I think both use the ZF? Can someone confirm?

Either way I think the GM is rated to 50K and the ZF to 60K between oil changes. Hence why the early GM boxes tend to fail, because being diesel they do a lot of miles, usually more than the petrol varients and they need an oil change sooner etc. 

Confusing.....

I'm looking at buying a TD6 Vogue, reading lots of old posts it appears that gearboxes 'can' give up around the 100k miles mark. I also read that the facelift 2006 TD6 uses a 6 speed box.

I guess if I buy something at the 80 - 90k mile mark, I need to budget for the possibility of a new box in the not too distant future..

If I buy one with a FLRSH, should the oil have been changed at the manufactures specified times?

LR say the box is "Sealed for life" this just means life of the warranty. Ideally if you change the oil as soon as you buy the car you should be OK. However, I may think twice about buying any car over 150K where it is definitely on the original gearbox oil. Unless you can budget for possible gearbox re-build.

When you do change the oil you will get an idea of the condition of the box (or your garage can tell you etc) if its full of cack then sell the car quick lol.

In reality, people complain loudest when things break - there are an awful lot of TD6's out there, they haven't all had failed gearboxes.

Good point I guess you don't hear much from those that haven't had problems. Like anything else, It's the bad news that makes the headlines..

The TD6 used the GM box up until it was replaced by the TDV8. The BMW 4.4 petrol used the ZF 5 speed and the AJ41 and AJV8 both used the ZF 6 Speed gearbox.

The GM box is a little fragile and has a reputation for failure after about 60k but as Dan say if yo look after it then you should be fine. The ZF 5 and 6 Speed boxes are in Land Rovers words sealed for life but both require a transmission oils change at 150k (yes that is correct 150k) in accordance with the manufacturers maintenance shedule. Land Roger know this and will, when the time comes, suggest this to you when you book your car in for service. Quite why you would use LR for service on such a high mileage car is beyond me but the oil change procedure is not difficul and can be done by any garage with the correct oil and additive. The sump seal and pan will need replacing a the same time. Can remember the capacity of the gearbox but it won't break the bank to do. 06MY 4.4 V8 Autobiography Cairns Blue with Navy & Parchment Interior

Steve, where is your source for the 150K figure?

I cant find anything that says that - the only references to 150K I can find is that is what BMW has deemed the acceptible life of their gearboxes is. However ZF seem to have released two lots of figures 50K and 60K. 

From the L322 07-on Service Sheet:

Replace transfer case fluid every 5 years/120,000 km.
Renew locking differential fluid every 5 years/120,000 km.
Renew front and rear axle oil, every 10 years.
Replace automatic transmission fluid and filter every 10 years/240,000 km.

My facelift TD6 is a 5 Speed.

I was very jealous last week, having driven the 8 Speed 4.4D  Apologies if i've posted this on my phone and it contains strange spelling and punctuation.. i just can't be bothered to correct it

I believe the Td6 kept the GM 5-speed even after facelift as the ZF was not a fit.

it was a while after the facelift that it got the gearbox with the gear lever nearer to the driver and i think the petrol was even later..... ... - .- -.
