thank you both for so helpful info! It was doing in S and normal mode at about same speed. I brought car back to the shop so cannot test it now. It does the sound when it shifted gears.
The serviceman didn't looked happy when he heard it, that usually means that he acknowledges his mistake. Not good. I guess i will try to get the gearbox fixed in ZF partner, i found on that website one nearby. I guess they wont take whole car, just the gearbox, right? I am at the shape to do anything to get my kitty back in perfect condition. Still have some moneys left and will get something for xmass too, i just gave it to them and told them to return it fixed. They should call me back when they find something for price confirmation.

 

p.s. do you know where i can find fuse from antennae? I want that it would not raise and retract every time i start the car because i do not need a radio.

 

Sandy, it is a 10amp fuse, fuse no.9 (There are
tiny numbers written in the black plastic you can
see.)

I agree, the car looks much sleeker with it down, as
I only use CD.

good luck with the gearbox! Hope your mechanic
sets it straight with you.

 

Look in the luggage compartment fuse box (remove the trunk floor panel near the antenna & battery is located). It is fuse# 9 and it is a 10 amp fuse and is for the operation of the antenna motor.

At least that is where our 2001 XJ Vehicle Care Manual lists it (also same location in 1999 & 2000 manuals).

Opps - looks like Ian already posted info, but did not tell you that it is the fusebox in the boot.

Here is a photo of a fusebox showing the fuse numbering format (shown is the front engine compartment fusebox - I do not have a photo of the boot fusebox):



The fuse numbers are on the outer edges - next to each fuse - photo shows fuses on left, relays in the middle, and fuses on the right).

Hi
I would like to say that Febi oil is used by BMW in thier ZF boxes it is alot cheaper than the Jag oil but has the same spec.

febi14738 is the spec and the Filter kit with the O-ring is febi31116 this is used by BMW and is the same as the Jag kit but again half the price.
Cheers

Jaguar do not specify the oil for the gearbox. The manufacturer, ZF, determines the correct oil & Jaguar merely include this in the specifications. These gearboxes are developed by the manufacturer using specific oils & if you don't use the exact oil, then you can get all sorts of problems.

These gearboxes have lots of internal multi-plate clutches, which are designed to work with a specific type of oil. If you use a different type of oil then it may have different friction characteristics. This can cause the internal gearbox clutch plates to slip, producing the squealing you hear as the gearbox changes gears.

Also, the fluids are specifically designed to work with the lock-up clutches on the torque converter. In the modern gearboxes, the torque converter lock-up clutch is not simply 'on' or 'off'. It's often designed to 'gradually' engage & dis-engage, and the correct transmission fluid plays a vital part in this process.

The fault has only started since you had the gearbox oil changed, therefore you can logically say that the different oil must be the cause of this entirely new fault.

Each time you hear the gearbox squeal as it changes gear, it's causing damage to the internal clutch plates as they are 'slipping'. This will eventually wear them out.

I would strongly advise you have the whole system flushed & then the fluid replaced with the EXACT fluid as specified by the gearbox manufacturer, ZF. It's your car, your gearbox & you have to live with the consequences of any decision. The cost of a new gearbox is vastly greater than the cost of a transmission fluid flush & replacement with the CORRECT oil.

ZF specifies the exact oil for this gearbox for a reason, so ignore what other garages tell you-they don't have to live with the consequences if your gearbox breaks!

 

Ditto!!, ZF build these trans, not local INDY shops.

Thats why people who do the trans flush have issues afterwards, because its either the wrong type fluild or to less.

I paid $120 for 6 liters of trans fluid when I did it for the BMW. while worth it, when I took it for a test drive and it shifted so so smooth. As with the people who took the cheaper route had problem within a weeks time.

 

thank you for the fuse info, wow this forum is awesome!

Regarding the gearbox, now i just have to pray (and pay) and deal with consequences. Even though i am poor chick i had no intentions to save moneys on that one. It is germany gearbox, and german car shop recommended me best german oil designed specifically for it. I should have called ZF probably directly, but honestly i didnt know. I rarely seen anybody who had issues with automatic gearbox so i was somehow hoping it would be no big deal situation in such car...

 

I understand what you are saying, but when you have an old car & limited budget you have to plan the maintenance carefully. You are the paying customer & the garage should follow your direct instructions-even if you just a poor chick

The gearbox is German & although your German car shop recommended a certain oil for it, there is only 1 oil recommended for it by the manufacturer-ZF. The gearbox is a mechanical device-it does not know about politics, finance, recommendations, opinions from other people etc.

All it knows is that it needs the correct oil specified by ZF. You must ignore the 'recommendations' of other garages. It's your car & your money, so tell the garage very firmly that you want the correct Esso LT 71141 fluid.

If you don't use this exact fluid, you could change from being just a poor chick to being a bankrupt chick if your gearbox fails

This will probably be the only time you'll ever need to change the oil during your time with the car, so it's best to do it properly & use the correct fluid-ZF only list 1 fluid type for this gearbox.

You've now seen the results of using a different type of fluid-your gearbox squeals when changing gear. This should tell you everything you need to know about ONLY using the correct Esso LT71141 fluid in this gearbox-as specified by the German manufacturer, ZF.

I would suggest you have the fluid changed soon if possible-it's unlikely that your gearbox will suddenly explode in the next few days. But don't leave it too long as every time you hear a squeal from the gearbox, it's gradually wearing out the internal multi plate clutches...

You'll need a complete transmission flush to also remove all the fluid from the gearbox AND the torque converter, followed by a complete system refill with the correct fluid. Yes, it won't be cheap, but the bill for a new gearbox will completely ruin your day

Once you've had this job done, it won't need doing again while you own the car-so it's a worthwhile investment to do it properly.

 

The low fluid level will not have helped the gearshift problem & may have caused the noise during gearshifts.

Do you know why the gearbox oil level was low? Did the garage not put enough of the LM oil in when you had it serviced recently? Is there a leak from the transmission oil cooler pipes?

When you get the car back with the gearbox level fully topped up, see how the car drives & if the gearbox squeal noise disappears. If the gearbox is now quiet & working properly, then the low oil level could have been the original problem.

As you say, drive the car for 200-300km & see if the gearboxs works perfectly normally. If it works normally & Liqui Moli have written certification that the oil is suitable for use in the ZF 5HP24 transmission, then you could be alright.

Your car has the smaller 3.2 litre engine so it won't put as much stress on the gearbox as the larger 4.0 litre engine. So you could get some use from the LM oil for around 6 months, and then next summer take the car directly to ZF for the gearbox service & full oil flush.

During the next few months just be aware of how the gearbox seems to be performing-if you notice any noises again or gearshift problems, then take it directly to ZF. I know LM has a good reputation for quality oils, so you could take the risk & continue to use the car for several months with the LM oil in & see how it performs.

You know that cats are often very choosy about what they like to eat

Are you aware of the other problem with the ZF 5HP24 gearbox? It has nothing to do with the oil type, but there is a design problem inside the gearbox valve block body. There are plastic 'checkball' valves which form part of the oil pressure regulating circuit. These car wear out prematurely, causing high pressure fluid 'spikes' which can blow the forward transmission 'A' clutch drum.

This causes instant failure with the loss of all forward gears.

The solution was for the gearbox sump to be removed, the valve block removed & the plastic checkballs to be replaced with metal parts. The valve block body also needs to be checked to see if it is work internally, or the new metal parts will not cure the original problem.

The symptoms of this fault are a delay in engaging gears when you select 'D' or 'R'. Then if you rev the engine in 'D', the transmission will suddenly engage gear with a lond 'thud' or 'bang' & this can blow the transmission drum inside the gearbox, which will mean a full gearbox repair.

If you notice any delays engaging gears when you select 'D' or 'R', you need to immediately take the car to a gearbox specialist for preventative maintenance. They will need to drain the gearbox, removes the sump, then removes the valve block body. They will need to check the valve block body & fit the new metal checkballs. if the valve block body is also worn, then this will also need to be replaced. Then the transmission underside is refitted & the gearbox refilled.

This can also be done as part of a normal gearbox service if you tell the garage to check these parts when they change the fluid.

I had a BMW 540i previously which had this fault-the gears wouldn't engage & when you revved the engine there was a loud 'bang' as the gears suddenly engaged. I had the gearbox serviced, new parts fitted to the valve block & new fluid fitted. Luckily I caught the fault in time before it destroyed the gearbox forward 'A' clutch drum, which would have needed a complete transmission overhaul & repair.

It cost around 500 Euros for this service & repair back in 2007, but it was still much cheaper than a complete new gearbox

 

thank you a lot for this exhaustive info and for your time you took to write it down, it is not wasted time :-).

i don't know why it was low on oil, car was not leaking when i had it (i checked it - i was rover driver before). before the service the gearbox was as smooth and silent as it only could be. I guess they just didnt put enough inside, but they told me it took about 10l of oil.
I will see. I will definitely go to ZF if the gearbox will behave good for about 200km to redo it. If it will cause further problems i will have to see if it is better to get rebuilt gearbox over ebay or have this one repaired.
this plasticky thing scares me, hope it will not affect me. I do not need a car often but when i do, if it would stop moving it would be disaster as i would miss appointment.

 

It's possible they just didn't put enough new oil inside the gearbox-hopefully it should be working properly again when you get the car back.

About this other gearbox problem-it was a known problem to Jaguar, BMW & ZF.

Normally you get warning symptoms before the gearbox fails. So when you put the gear selector lever in 'D' or R', you should feel it engage almost immediately-or within a couple of seconds at the most.

If the gearbox takes a long time to engage-like 4 or 5 seconds-then you have the warning symptoms & should take the car to a gearbox specialist for examination & repair. At this stage you don't have to have the complete gearbox rebuilt-just the valve block & checkballs, with new oil when the garage re-assembles the parts.

If you ignore the symptoms then the gearbox could fail completely later & the car would not move. As I said above, you do get warning symptoms before the gearbox fails completely-the problems only happen if you ignore the warning symptoms!

When the ZF gearbox on my old BMW started to take 3 or 4 seconds to engage gears, the car still worked normally for several months-that's when I learned about the particular problem & took the car to a local gearbox specialist for the preventative repairs & new gearbox fluid.

So don't panic too much now-the problems only happen if you ignore the warning symptoms & do nothing about them

If you drive the car normally & continue to observe how the gearbox functions, you should be alright. However, if you ever start to notice this delay when engaging gears-take the car to a gearbox specialist. The problem is well-known anyway, so they will know what you're talking about if you get this problem.

For now though, just enjoy the big cat when you get it back from the garage & continue to monitor your kitty

Yes, low fluid would have created that noise, since you can't get your money back, you gambling with your finances keeping the fluid in there. Just chalk it to life lesson learned.

If you can afford it, take it directly to ZF after you get it back and have them do a full service on it. Still, will turn out cheaper than getting a new gearbox.

On the BMW forum, a member took his BMW to ZF and they did a awesome job.

 

i will definitely do it, but as said, i want to make sure the gearbox is ok. If i will have within 300km some issues with it, i will try to get the shop acknowledge the issue and pay for the (more expensive) fix.
If it will work fine, the price for two flushes in one month have to be chalked as life lesson :-(.
ZF were very friendly on the phone and were standing a lot behind their gearbox, saying it is good product but the way it works just have some things which have to be followed.
You know i bought this car to be my last one. I have been wanting one since probably i was born (ok i wanted old XJ12 coupe but was not able to get one and this is as close as it gets with lot of added positives). No, i am not that old, i just dislike modern cars and this one is just what i needed. Have been saving for it a long time and made lot of visits on various XJ8 before i got this one. It is a heart issue for me, not just accidental purchase :-)

 

I'm feeling with you, Sandy, and I press my thumbs very hard that in the end everything will turn out all right for you. I hope that after this crisis is overcome you'll spent many many happy years with your cat, which one fine day will wear the shiny gold paint you're wishing for!
(wondering if the gold would chime together with the sapphire blue of my Daimler )

 

Yes, you merely buy other cars but you lust for a Jaguar & it's a love affair

When I saw the advert for my Pacific Blue XJR in 2008, it was 'love at first sight' & I immediately went to see it at the weekend-even though it was 300km away from me down in the South of England!

When I bought it I had the fastest drive home in history as I learned how useful a supercharger can be

The only sad part for me was that I had to part-exchange my 1995 Daimler Double Six to get the XJR & I still miss that big V12 engine with it's effortless power. That had a much simpler gearbox which took the good old Dexron III fluid which was available in any car parts places.

Anyway, hope you get your big cat back soon & that it works nicely again. Then you can plan the budget requirements for the gearbox service at ZF

 

Me too, when I saw the advert for my 1998 Sapphire Blue XJR I drove over 200 US miles to get test it TWICE. It was love at first sight.

I call the dealer so many times questioning the car, they knew my phone number by heart.

You get it all sorted out in time.

From what I hear about ZF customer service, it is a wonderful experience. They stand behind the product and name.

 

That might be front lower balljoints-mine creaked & clonked a bit at the front until I replaced them. It wasn't a pleasant job though as they would not move & were very difficult to change.

We are not crazy for loving our Jags-we are all perfectly normal

It's everybody else who is crazy & doesn't understand!

 

exactly...
