4.4L TDV8 ZF 8HP70 flush : special technique?

Hi Gang,

My 4.4L TDV8 L322 will soon get a 8spped transmission full flush (as in they plug to the transmission fluid circuit and inject more oil that it would contain, replacing 100% of the old oil and the fit a new ZF filter.

Since they have not done it yet on a 4.4L L322, (they did my 4.L4 Petrol one and many Sports, Disco and so on of course, being a ZF retailer) so I wanted to check with any specialist here if there is a particular technique to do it (i.e. lift the engine à la TDV6 RRS and Disco 3/4? or any thing I should know/tell them?

Thanks in advance Lads.

I have already send a message about this to Craig Meister lads but there might be transmisison specialist here too - feedback will be useful for all current and upcoming owners here l=Oo\________/oO=l l:OolÎžÎžÎžÎžÎžÎžÎžloO:l

I’ll be looking to buy a 2012 L322 in the summer (Westminster or Autobiography) so I need to do some swotting up on the 8HP70 before them. If I can find a used transmission cheap enough I’ll maybe buy one off eBay and get it to pieces.

Regarding fluid changes, let’s start with the manufacturer’s recommendations. Like all the latest ZF units i.e. from the 5-speeds onward, ZF say the 8HP70 transmission is ‘lifetime fill’ and only recommend a fluid change at 50,000 to 75,000 miles if the vehicle has :
a) done a lot of continuous running at high speed
b) been thrashed
c) been used a lot for towing
i.e. conditions that would cause the fluid to run at elevated temperatures and therefore accelerate the oxidation process

This is detailed in their TE-ML_11 specification which is updated every few months :

http://www.zf.com/media/media/en/document/...-ML_11.pdf

Interestingly, Land Rover recommend a fluid change at only 30,000 miles for the 8HP70 for ‘severe duty’ maintenance.

It’s imperative that any fluid change procedure uses the correct fluid – in this case ZF Lifeguard Fluid 8

ZF Lifeguard Fluid 8 was originally Shell L12108 so it’s interesting to see ZF’s recently-added reference to the Petronas Tutela fluid which is fully, rather than partially, synthetic.

None of the recommendations mention filter changes.

I would strongly recommend that only a genuine Filtran sump pan/filter should be used as there are a number of cheap(er) pattern parts out there. I notice, for example, that Britpart offer a service kit with the correct fluid

but I have no idea whether the sump pan is a genuine Filtran one or not.

Land Rover sell the sump kit LR065238 (was LR023294) for around £180 and the fluid (LR023288) for an eye-watering £48.90 per litre so it’s understandable that people will shop around. The Lifeguard Fluid 8 on eBay seems to all come from Germany and is priced at around £17-£18/litre (including delivery). Incar sell it for £23.94/litre.

The sump pan on the Range Rover can be replaced without having to resort to releasing the engine mount and jacking up the engine like they had to on the Disco 3/4 (hence people swapping out the 6HP26 plastic sumps for the steel ones with the separate filter).

My preference (and I emphasize that this is just my personal opinion) would be to drain and refill the transmission every 30,000 miles, with a sump pan/filter change at every other refill (i.e. every 60,000 miles). Clearly a drain and refill is just a fluid ‘refresh’ as it only replaces around half of the fluid and therefore shouldn’t upset the existing transmission adaptions too much and risk overloading the clutches as they struggle to re-establish the specified shift times.

Regarding flushing - if they use the genuine fluid for the flushing process then I would imagine that it must be very expensive due to the wastage. If they instead use a cheaper ‘compatible’ fluid then I personally would stay well away. I think you should first check what fluid they’re intending to use.

EDIT :

Checked with them, they do use ZF's oils and Filtran filters l=Oo\________/oO=l l:OolÎžÎžÎžÎžÎžÎžÎžloO:l

Ahh yes, of course, Petronas are a Malaysian company

This is a copy of the same section from ZF’s TE-ML_11 specification from exactly a year ago (January 2014) and, as you can see, there’s no mention of the Tutela AS8 fluid.

Eugene,

Just for the avoidance of doubt, the ZF 6HP28X transmission fitted in your 5.0 SC Range Rover uses Lifeguard Fluid 6 (Shell M1375.4) and it's only the 6HP28AF versions, with the integral 4WD for Audi and Bentley, which use Lifeguard Fluid 8.

2014 Range Rover Vogue SE SDV8 Santorini Black

I am just thinking about this oil and filter change for the 8 speed box myself, have asked Dan for the parts prices.

Did you either of you ever get this gearbox oil and filter change done, if so what did you do and what were the results?

Nothing wrong with mine at all, it's just done decent (90/-) miles and I am thinking that oil is cheaper than gearboxes......

Hi, did mine (on the 4.4L TDV8) at 115.000 Km, did not feel any difference but the oil was obviously used and dirty.

I would really recommend it since, as you've mentioned, oil is cheaper than a box.

That said, the 8 speed box is pretty much bulletproof, but oil and filter renewal will certainly be an asset once you wish to sell or if you keep the Rangie for another 50/60.000 Km - which is the period the oil should be replaced if you want to keep it forever. l=Oo\________/oO=l l:OolÎžÎžÎžÎžÎžÎžÎžloO:l

2013 Range Rover Autobiography SDV8 Baltic Blue

I've just been quoted £199.00 plus vat for the Britpart kit DA6106 which sounds quite reasonable to me given the fluid prices mentioned above.

Three questions of those who are more knowledgeable than me...

1. is the filter part of the pan or is is a separate item (outside this Britpart kit) and
2. for a averagely competent person - is the fluid change a DIY job?
3. any special tools required. I've checked the wiki but nothing so far.

Hi

This kit will only replace 50% of the fluid, I would really try to find a specialist that would replace 100%. More expensive but much more efficient.

Otherwise, yes, the standard flush is doable by any DIYer indeed. NOT so much when it comes to replace 100%, as you need the machine and there is a temperature activated valve that will not let you flush it all that easy anyway.

So in a nutshell :
- 50% flush for £200: good
- 100% flush pobably +£400: excellent

But both solutions are better than not doing anything! l=Oo\________/oO=l l:OolÎžÎžÎžÎžÎžÎžÎžloO:l
