If you're planning to do another drain/fill, then go ahead with a pukka OE filter and fresh fluid as that way you will further dilute what remains of the old stuff in the TC. What did you choose for the replacement fluid?
Odd that the rattle seems to vary dependent on the A/C compressor activating as that indicates the issue may be somewhere in the accessory drive train.
Does the ABS light appear immediately when you start up the car or only after a trip?

Thanks Michael I think I'll put a few miles on It and change the filter and fluid again when I get into my garage.
We're buying our first house at the moment so the Jag doesn't have great timing but hopefully she can stay in one piece for a few more weeks....!
I used Valvoline Maxlife fluid because it's rated for LT41171 - I debated getting the proper stuff but maybe I'll do that after a could more flushes...
And yeah the A/C load affecting the rattle is weird... I note that in the ZF guide to refilling the tranny it specifies running the A/C to get the most about of fluid in the transmission so I guess it makes sense somehow. It does seem to be accessory line related though as the noise is affected by electrical load like the rear demister or fog lights....
I did record a video of the whole thing but when I didn't have a triumphant ending I couldn't face posting it!
At the moment the ABS light seems to remain on 90% of the time after starting the engine.
I'd say 80% of the time that is followed by the "Stability Control Fail" amber warnig message... it also seems like on the times the warnings do not pop up, the cars seems livelier and more free revving. But that might just be some mental association I have causing feelings of depression and inadequacy when I see a warning light on a dash...

Hi,
Certainly put a few miles on to give the fluid time to circulate before you do another drain/fill.
Just curious about the choice of fluid as there was much debate when LT71141 was the price of liquid gold. ZF used to mandate Lifeguard 5 (which is the same stuff) in the 5HP else the world would stop turning. I did as I managed a good deal on a 20 litre drum from the company that supplies our central heating oil ('temperate' climate here), but there are several alternatives these days.
Electrical load (think alternator) also translates to accessory train load so essentially the same thing. Power steering - does turning the steering wheel have any effect?
If you're seeing the ABS warning at start-up, it's likely the ABS motor power supply connector issue. Wiggling the plug used to make it go away on mine for a while until it eventually became more permanent and I had to get the hacksaw and soldering iron out.
Good luck on the house move. That's something that should be fairly painless but it never is...

Please forgive me, but I'm about to get on my soapbox!
One thing we've learned is that Valvoline cannot be trusted regarding the specifications its fluids are claimed to meet. Apparently, they are able to offer fluids at lower prices by compromizing the formulations to make them "suitable" or "just good enough" for use in a wide variety of vehicles. But a fluid "good enough" for use in so many gearboxes can't possibly be optimal for use in any of them.
For example, Valvoline claims its MaxLife Import Multi-Vehicle Transmission Fluid is suitable for use in ZF 3-speed, 4-speed, 5-speed, 6-speed, 8-speed and 9-speed transmissions. Yet ZF insists that the 3-/4-, 5-, 6-, and 8-/9-speed boxes require four different fluids, and if you check the Material Data Safety Sheets for those fluids, you'll find that their chemical properties are quite different from one another.
As another example, Valvoline claims that this same fluid is suitable for use in Ford vehicles that require Mercon SP, Mercon V or Mercon LV. Yet Ford insists that these fluids are not interchangeable and, for example, Mercon LV must never be used in a transmission that requires Mercon V, and vice-versa. By the way, Mercon SP is equivalent to ZF Lifeguard 6, which is VERY differrent from Lifeguard 5, yet Valvoline claims their fluid is a suitable replacement for both!
Here's a link to the product info sheet in which Valvoline makes its implausible claims:
Valvoline MaxLife Import Multi-Vehicle Transmission Fluid Product Sheet
The fluids I am aware of that are correct for use in the ZF 5HP24 are:
ZF Lifeguard 5
ESSO LT 71141
Febi Automatikgetriebeol (ATF) Nr. 29738
VW/Audi G 052 162 A2
Pentosin ATF 1
Ravenol ATF 4/5 HP
In the U.S., I have found the best availability and pricing on the Febi and Pentosin fluids.
Sorry to rant, but Valvoline's application claims are one of my pet peeves.
Cheers,
Don

I had the same issue on my X308 (which also has the 5HP24) and ended up replacing the entire transmission and torque converter with a second hand one.
Now that I have bought a second X308, I'm running into the exact same issue. I'm curious to what the actual problem is, before replacing the transmission again.
Your symptoms and the sound on the video are the same as mine. At cold start it is noticeable but it gets worse when the idle settles.
I would love to hear from you and what progress (if any) you've made or news you might have 😁

Hi Pistnbroke,
When the time my gearbox made a strange noise, I also made a video where the sound can be heard well (without any lawnmowers ).
Was the sound you had by any chance exactly the same?
With this 'noisy' gearbox I had recently replaced the fluid and filter with a kit from a site called britishparts.co.uk. It wasn't too expensive for a probably failing gearbox (or so I thought ).
It contained a fluid called 'Granville ATF MV (multi vehicle)' and also came with a (probably) a not-so-German filter.
With the posts in this forum I'm starting to have my doubts whether my old gearbox really was broken, or just had the wrong oil / filter.
When I replaced the gearbox I had ordered a kit from ZF, with an original filter and 'ZF LifeGuard fluid'. Still works great.
I know the sound of a dying pump. That 'grinds' too, but these are two very different sounds. I'm curious if this is really the same sound you heard.

that does not sound like mine did which had a much tinnier sound. more like rattling baffles . Just like Dickerson .I noticed it most when driving past a 100 yeard long brick wall with the passenger window open at about 20 mph. Lots of brick walls here with brick houses close to the road .

I am trying to send a copy of your video to my gearbox expert ..retired ..he does not open his e mails every day but if he has heard it he will know .
Update
Managed to get a copy to him but we now have to wait .

Sorry to say my Jag hasn't moved for a while - she's in the garage waiting until I have some time :-/
I do plan on getting her up and dropping the transmission - I'll have a look at it and hopefully replacing the torque converter will do they trick. I just won't be able to justify the cost of taking it to someone for a rebuild to my wife so I'll have to tackle it alone

I only had the rattle sound when the engine was cold..when hot it changed to a rythmical grind/rumble.
If you are determined to take out the tranny then why not put in a proper filter first and correct oil. If it dont cure it you can re use the oil and filter on your re build ..I think you can pull the torque converter from the front so nothing lost.
Here is the MEYLE one from germany £21 Item no

That's a great idea actually... certainly worth a try!
I can at least drain it first and see if there's anything nasty lurking in the pan before dropping the whole thing out... I do miss driving her!
