( S-Type 3.0 v6 Sport 2002 )

Hello All, recently bought an S-type Jag, got it knowing the gear box required replacing, and duly did so. Second hand box fitted, and car drove like a dream for about 20 miles, and then gear box fault message showed and gear box juddered into 4th (limp mode). Took back to gearbox centre who fitted the box, they cleared the codes, and once again it was fine for about 20 miles. Gear box centre are telling me ive been sent a duff gear box. The company I bought the box off have sent out a replacement; however before i pay to have the box fitted, is there anything else i should be looking for, anything else it could be.

The last thing I want to do is replace this box, if the problem lies elsewhere. I understand that the electronics play a big part in all this, however the fact that it has twice run perfect on 2 occasions leads me to believe that mechanically the box must be sound. Any ideas or input would be appreciated. Many thanks

Thankyou

 

This is the 5 speed Ford trans, NO??.

Yes, they have issues, we all know that, and s/hand ones that have been neglected as many "in car" units have, are no better than what you have.

Some trans/limp issues have been eventually traced to a battery past its use by date. These cars rely on a battery being "right up to snuff", or the gremlins will do weird stuff.

The code clearing, and then it appears OK, has me thinking battery.

Both my X200's had "suspect" trans operatiom when we first got the cars, and multiple fluid changes, and a new battery in the Silver car has them as good as I want them.

Nearly forgot, WELCOME to the Forums.

 

Hello Grant, thankyou for the welcome and also the advice. One thing I forgot mention was that there are a couple of other intermittent faults. I get low engine coolant, ABS fault and the speedo not working properly. All intermittent, and seemingly random. Does this firm up or change your opinion of the battery being a possible cause.

Many thanks
Colonel Mustard

 

In a word, NOPE.

All them have been mentioned over many years of "strange" stuff on X300, S Type, XJ8, XK8, etc cars.

In a lot of cases a new battery fixed them.

Down here the battery for the S Type is a Din88, or a N88. Same battery, diferent label.

 

Sure sounds like low battery but without car details we're guessing it's not (say) a loom fault.

 

JagV8, thanks for your input, what kind of detail are you after? According to the log book I am driving a Jaguar s-type v6 sport auto, registered 16th October 2002, 2 axle rigid body, petrol.

Hope that helps
Cheers

Ahh... it's likely after VIN M45254 (change occurred during 2002) and if so will use the ZF 6HP26 box. They're pretty solid.

That's no guarantee but... maybe there's a fault that upsets the box - and these DO happen.

Usually it's an engine fault. Yeah, sounds weird but isn't.

The two co-operate all the time, especially on gear changes. (Packets sent on the CAN bus.)

The usual upsets to the engine are air leaks, bad coils etc.

Cheapest way to start hunting is an elm327 OBD tool. Grab any codes and tell us. Check engine goes closed loop within about 30 secs and then look at fuel trims. Post if they're away from zero (hot engine, parked) by more than about 5.

Your engine will have IMT O-rings that probably need replacing anyway - see the Stickies/FAQs. Have a look at other FAQs by joycesjag as Rick posted vacuum lines and other good stuff.

 

Rego date means nothing.

The car could have sat around for 12 months??.

The VIN # is the only way.

Thw X200 go to about 6/2002 BUILD DATE, and have the 5 speed Ford family trans, and the Jaguar Growler is in the Bonnet (hood).

The X202 and onwards start in about 6/2002 and have the 6 speed ZF trans, and the Jaguar Growler is in the Grille.

The build date is on a plate alongside the spare wheel on the LH side of that wheel well in the boot (trunk), towards the front. Easily spotted.

We really need to know the VIN, and/or the build date of that car to continue with proper responses.

 

JagV8 and Grant, thanks for all your help, blown away by how knowledgeable you are.

Looked, but could not find plate with build date on. The growler is on the grille, and the vin is SAJAC03P43FM6632.

I have had a fault reader on it and these are the codes:
current P0731, P0732
Pending: P0731. P0732, P1000, C1175

Cheers

 

There's an easier way to tell. Does the center dash panel look like this:


(1999 to 2002 model year)




or this

(2002.5 to 2008 model year)

 

Hi Mikey, neither. Mine has the large touch screen console
Cheers

 

It's after M45254 and in UK as well so it's a ZF. Redesign-type car.

C1175 is about LH rear wheel speed sensor. (You have RHD car.)

eek, not liking the looks of P0731 & P0732.

(I wonder if they can come up for the shifter cable.)

hmm... may be worth finding out:
1. what trans fluid they put in
2. what procedure they followed to ensure correct fill

The box is fussy on both counts.

But... #1 suspect is still the battery!

 

Thanks JagV8, have had a quick look at the battery, there is white deposits on the terminals, does this indicate a knackered battery? As you can probably tell from my questions I know almost nothing about cars, other than how to drive them, and some say even thats a stretch!
Cheers

 

It's not a good sign, you should remove the terminals and get them cleaned up then have the battery load tested and/or fully charged.
You may need to think about getting the Trans fluid level checked, there is a very specific procedure.

 

Then it is not a 1999-2002 model year car. It's properly called a 2002.5 within the UK or 2003 elsewhere. Nicknamed a 'facelift' car.

Makes a huge difference in technical discussion and parts sourcing.

 

You have a post 2002 model. Here's another tip on your transmission selector do you have:

1,2,3,4 - D

Or

1,2,3,4,5 - D

 

I am sure he'll have the one with 5.

Let's hope it's an aged battery.

Just noticed the VIN given is missing a digit...

 

Sorry about that JagV8, here it is again hopefully complete this time: SAJAC03P43FM66327
Thanks
