Jimmy's Jaaag of niggles.

[Jimmycrackcorn]

I'll update this properly later with real pics n everythin.

 

 

I'm away from home at the moment down south so I got to take my S-Type on a good run as I hadn't been able to before.

I work for a Jag Breakers that specializes in X-Types so it was a bit of an unknown but it fired up fine and I took it for a little drive (no tax-mot-ins) as far I could within a little back street. Anyway gearbox seemed fine ran it through the gears etc and all seemed fine. 

Got it Mot's and ran it around a little and showed no symptoms however I hadn't taken it over 40, on the drive down south above 40 the car would judder and lurch so I presume slipping. Going between 40-50 etc the engine management light flashes but once you settle on a speed and maintain it it goes goes out and the car runs fine, the only difference to this is if you go up an incline it feels like it's slipping again.

Also noticed that if you boot it when cold it'll run through the gears with no issues and work as expected.

It's a 99 S-Type 3.0 V6, 

My dilemma is the car only cost £200 and as far as I can tell it'll cost me that much for the ATF it needs let alone a new gearbox filter which is sold as a complete unit with the sump.

I had hoped to just empty the fluid and replace it with Dextron II but that doesn;t seem to be an option.

My other option is just to put up with it til it dies but the engine is sweet (bar maybe a blocked injection as the idle is a little rough) and it's been well maintained (150k full dealer service, only service it's missed is 160k currently 167k as the last owner couldn't be bothered).

 

tl:dr borked gearbox, cheap fix or not?

[NorthernMonkey]

It would be handy to scan it with something that'll read transmission codes and you could also double check the fluid level isn't too high but tbh my overriding instinct is worn out clutch(s)....sorry

[Jimmycrackcorn]

It's a "sealed for life unit" so as far as I know it's never been touched. We've dealer software at work so I'll plug it in and see if that brings anything up.

If it is slipping clutch I presume that it's just a case of bunging a new box on (I think we've one on the shelf funnily enough). I am tempted it run it as is until it ftp's as when I'm back home it'll mostly be ding sub 50 anyway.

[Bren]

The biggest single weakness of the car.

 

Given the mileage and what you paid for it use it until it dies.

 

No point spending money chasing faults that are uneconomical to repair.

[bigfella2]

If you can get the codes read, then great. If not get some atf and a filter and give that a try. If no change I would stick it in a car auction. Hopefully one of the mongs off deals, steals and wheels might bid on it, especially the one that looks like brewer.

[Jimmycrackcorn]

That was my intention and when the inevitable comes I'll just break it at work and pick another for £200 (although maybe a Spanish waiter) we're getting offered them quite often and I've been talking to the boss about getting other models in so I'm not too worried. But if there was a good chance a change of fluid would have fixed it I would have gone down that route.

[Guest Lord Sward]

I thought a gallon of ATF was relatively cheap?  Not that I think that'll effect much of a cure.

 

I've had autoboxes die on me in both XJ, S-Type and X-Type. 

[Jimmycrackcorn]

It's special Unicorn piss at £22 a litre for the ZF gearbox.  

[cort16]

I had the same dilemma on a spotter 740i I had. The oil alone was well over 100 qui.  Given these s-types reputation for lunching autoboxes it possibly won't fix it.

[Jimmycrackcorn]

I'm more at ease with it now I know it's not worth trying to fix and I've got recovery so if it goes it goes.

As long as I don't accelerate it's fine so meh.

[Stixy]

Sounds a speed sensor issue to me , but get the codes read  before you touch the oil  . 

[SiC]

Is this:

Or

http://pages.ebay.com/link/?nav=item.view&id=361457365478&alt=web

The right oil?

 

Seen that seller posted around a couple of times on different forums for cheap ATF. I've never used myself but the other posters said good things.

[Jimmycrackcorn]

Hmm, I've just had a quick look on ECP and that brings up Dexron II or III, 

Pretty sire the box is a  ZF 6HP26.

[Jimmycrackcorn]

Which would bring up this http://www.ebay.co.uk/itm/Jaguar-ZF-OEM-6HP26-Auto-transmission-gearbox-fluid-service-kit-DA6085G-/181715824059?hash=item2a4f1b6dbb:g:l2EAAOxysE5Sak4F

I'll plug it in at work and see what it brings up.

[Mr A Lawrence]

That's the box in the 2003 onwards, 6 spd.

 

Yours will be the 5R55N 5 spd.

Now if that's the case it'll be considerably cheaper and may be worth attempting depending on what the computer says. 

[Jimmycrackcorn]

This seems pretty cheap so I could reasonably do it for about £60.

[Mr A Lawrence]

That'll be the cure alright, although jag did say it's a sealed for life box they now recommend a service every 80or so thousand miles so, at 160 it's about due going on if it's had it done on 80k mark.

 

Might also be worth doing a software flash too.

[Jimmycrackcorn]

I drove home last night via bit of a detour (400 miles all in) and one thing I noticed is that say I came off a roundabout or sliproad and hit resume on the cruise control it didn't have the same issue and came up to speed beautifully. 

[Jimmycrackcorn]

Any idea why it doesn't seem to do it when hitting resume on the cruise control?

Haven't had time to plug it in at work due to catching up on orders.

By the way if your car develops an annoying wub wub wub type noise that'll be the front wheel nuts loose.

[michael1703]

Had similar on a merc with an auto box,had to give it a flush and it sorted it.

 

Felt like slipping clutch on that too

[Jimmycrackcorn]

Spoke to the boss and he thinks the same so singers crossed I'll do it at the end of the month. It's got a bit of a rough Idle so I'll completely service it front to back.

We've just gotten another S-Type in so I'll be pillaging that for parts.

[Jimmycrackcorn]

Is there enough interest/shiteness in my S Type to change it to a proper thread?

[DVee8]

Yeah just do it.

A few of us have had S-Type Jaguars.I have had a R and a 3.0 se petrol.

[Mr A Lawrence]

Yeah, do it!

 

The early ones are falling into autoshite territory.

[DVee8]

J-C-C do you get into any of the older Jag/Daimler stuff? Not for braking but for repair? i have a 1968 Daimler 250 V8,i did use Webbs at Penshaw.

[djimbob]

Is there enough interest/shiteness in my S Type to change it to a proper thread?

 

Please do, I am after similar in the near future, no doubt at rock bottom prices so with loads of niggles, forewarned is forearmed and all that

[Jimmycrackcorn]

I'll do a proper thread, I'll get some pics up.

[Jimmycrackcorn]

Took the boss out for a spin and he think's it's actually misfiring so either plugs or a coil however plugging it in shows no error codes despite getting it to flash the engine management light on for a couple of seconds.

He said the gearbox is controlled by it's own ECU and it would but the car in limp if it was that causing it.

So I'll order a set of plugs £12 for 6 Bosch Super Sparks on eBay and try that first. 

[cort16]

A dodgy maf can cause the gearbox to freak out. You could try unplugging it and see what happens. I've had this happen on 2 different cars.
