Transmission (Gear Box Failure)
 

Well first of all I have gotten a gear box failure. It occurred roughly 3 weeks ago when I was on the freeway. I was driving at least 65 MPH and I just pressed the button to drive in a cruise control setting. Once I did that my car did a massive lag, and the gear box failure popped up while that happened I just pulled over to the side. I just turned the car off and on then it worked well. Since then no gear box failure has happened thankfully. I would just like to know if anyone has had such an issue with their X-type. Thanks Alfredo209

alfredo, it seems to me that your car went into what is called LIMP mode where the cars performance is limited so that the damage done to the car will be minor. A lot of times with random gearbox failures like this, it has to do with your electrical system. I have seen many xtypes that get gearbox failures when their battery cables get corroded or if the battery is on its way out. The good part about it is that if it was something major and something that would prohibit you from driving the car, the light would have come back on within these 3 weeks. If your car is an auto gearbox though, it never hurts to check your atf fluid level because the xtype is VERY picky about its fluid level in the auto trannys.

Disguay thank you very much. Very useful I will check that out. I also need a tune up any how so that will possibly be the major issue as well.

gearbox fault
 

I too had a similar problem with my x-type 2.2l diesel 2009
Driving home on freeway the orange light came on and the digital display said gearbox fault, I too pulled over couldnt see anything so restarted car and all was well, that was 2 weeks ago
also the glow plug light came on but I think that is a equiv of an engine warning light too.
so far all ok I assumed it was a sensor glitch.

Disguay thank you for the information. How do you check and add the transmission fluid levels. I was told that it is a sealed transmission and only the dealer can change the tranny oil. Please help because I'm lost....

Because I own a manual transmission, I do not know how to check the automatic transmission fluid, however this thread may help you: X-Type Transmission and Transfer Case Fluid Levels

Guys the tranny is sealed (at least on my 2009 x type)although it can be serviced.
They have found the problem with mine at last, it was a burnt fuel pump in the tank
it wasnt pumping enough fuel through and was intermittant, probably why it went into limp mode.
However they wont give me the car back until they know why it failed, as its only 3 years old and a rare occurance.
although this doesnt explain why it came up with "gearbox fault"
hopefully I'll have some news this week.

fault light
 

The ongoing saga of my 2009 x type:-
Been at jag specialists for 3 weeks now, they replaced the fuel pump and it drives well, spent 2 weeks looking for reason it failed, finally decided to hand the car back, but the boss decided to take it home to test it out on a decent run and it failed yet again, they think its an electrical problem. and are now continuing to try to find it, in liason with jaguar UK.
they have now had the car longer than i have.
wish I kep my reliable Holden now.

gearbox fault light
 

Well finally got my x type back after 6 weeks at shop
They still do not know what caused the problem but assure me its going fine now (we'll see)
They had long conversations with the UK about computer settings etc, they cleaned the fuel system out twice and replaced the fuel filter
check all electrical circuits, although the car did fail twice while they had it they cannot find the cause.
The only symtoms they found was the car would not start after 2 days sitting, no codes came up, they assumed it was an electrical or computer fault as it kept going into limp mode initially.
but at the end of the day its running better than it did when I bought it, the vibration has gone which I assumed was normal for a diesel.
hopefully I'll have smooth driving over christmas.

I've had the gearbox fault come on when I turn cruise control on and off to much while driving because I'm to lazy to press cancel or on the brake.

wont start
 

Yes it was too good to be true, got the jag back thursday all good as I previously posted, but 2 days later it started to cough on accelleration on way home form party, it made it home ok, but next morning wont start
RAA couldnt start it so its back to the workshop again.
anyone want to buy a jag?
Lost all confidence in it now, when/if I get it back its going up for sale
not bad 1 1/2 weeks of actually driving it $28,000 later and its going
sorry to leave the forum as its been very informative but not much point if I dont have a jag
Cheers to all those who posted responses

gearbox
 

mine was pitching the gearbox message too. After doing some investigating it turned out my generator was putting out over 16 volts at the battery. I disconnected the gen for abit and the trans shifted fine. Now I gotta figure the charge issues

I've just spent 2 hours reading and skimming through all the threads with info on the Transmission Fault code. This is brutal. Everyone warned me about buying a Jag. I listened and then ignored them.

'04 X-Type Wagon, automatic tranny, 120,000 kms. Appeared to be very well maintained. It needed a few things when we bought it. Nothing crazy. Then the Tranny Fault issues started. The first 2 times it came up while driving and seemed to go into limp mode. Pulled over. Shut off and on again and the message went away. After the second time I finally caved and took it to a Jag dealer. It had so many error codes that they suspected electrical issues.

I'd recently had the battery replaced when it wouldn't start for me. The AAA tech also advised me that the alternator seemed to be over charging and needed to be replaced. I mentioned it to the Jag Dealer and they confirmed the alternator was over charging and likely on it's way out, should be replaced. Approx. $800 for the alt. I picked one up at an after market parts dealer for $300 and had them install it.

Problem solved, I thought.

Yesterday it had the same problem, only when I tried to restart it it wouldn't turn over. I was stopped in a bad spot and thought I'd just push it a few feet. I could't get it into neutral. I tried disconnecting the battery for a few minutes. Same problem. When my neighbour came out to see why I was blocking his driveway we chatted for a few minutes. Then it started, no Tranny error message but now the engine light is on.

From all the other suspected diagnosis I've read I think it may be a leak water and resulting electrical issue. It seems to happen when it's wet. we had a bit of a thaw here yesterday. Things were quite humid. The other 2 times it was raining.

One of the things we had repaired when we purchased the car was the front windshield. That will be the first thing I suggest to the mechanics.

It's my wife's car which I steered her to. If I don't get this figured out I'll be in the dog house for years!!! We both love the car. It's everything she wanted, wagon, heated leather seats, sun roof, automatic tranny (not my choice). It's beautiful. She is so proud of her first car in over the 25 years. This has to get sorted.

Keeping my fingers crossed for a great mechanic!

Cheers

Good Luck on that one, hope it's a Happy Ending!

fuel pump
 

It turns out after all the trouble I,ve had its definately the fuel pump not the one in the tank but on the engine, they have the new one ready to go in, but guess what?...yep it needs special tools to install and set it, and no-one in Oz has them so now waiting for tools to arrive from the UK
they assure me i,ll get it back this year.

The best of luck to you!

A.T. I am in same relative situation as you. Wondering why the "Gearbax Fault" "Trac not available" "ASC not available" and ABS light have not risen to the level of recall from the manufacturer. It seems like these are all related and that there is no cure. different things work for different people but both the occurence and the cures are almost random. I think its Jaguar Cancer.

Guys, I may actually have something constructive to contribute for once.

I finally took the JagWag to The Cat's Cradle in Toronto. It took 2 visits but I think we've got this licked.

The first attempt at a remedy was to replace a grommet around part of the wiring harness which passes through the firewall to a bunch of stuff under the dash. There was some minor corrosion from water traveling along the wiring harness at that point. But that didn't do it either. Still had the same problem the next time I drove it. There was a major clue this time though. It happened while stopped at a light. I was trying to adjust the seat when and all the dash lights came on plus the old Transmission Fault error message. I thought I'd blow a gasket at that point. Fortunately, in the middle of my rant to Mike, my mechanic at Cat's Cradle, I mentioned the seat adjusting. And even more fortunate, he wasn't too proud to ask another Jag mechanic about the issue. The other mechanic knew right away what the issue was.

Apparently there is a part of the wiring harness under the driver's seat which is positioned in such a way as to rub against the seat frame or rail every time a seat adjustment is made, eventually wearing through the insulation and shorting out the wire. Because it's connected with the airbag system the computer shuts things down if there is any problem with that circuit, including the function of the tranny.

That's my story (or my mechanic's anyway) and I'm sticking to it and keeping my fingers crossed. So far no more issues with that. We've put 500 kms on it since then.

I'd love to know if this makes sense to anybody. I'd be very pleased if this turned out to be a solution for someone else as well.

Cheers

same thing happened to me on the highway, heavy braking and gear failure appears off and on again it works for 100 km and then turns back on until I turn off ... as continued your experience?

Hey lucas1

Did you check for shorts in the wiring under the seat?

Cheers
