My transmission lasted till 72,000. I also needed to have my shifter assembly changed, as it started to get a loose grab..(noticed at the same time) I was bummed about doing it, since I bought the car used and it went out after one year...but then I realized I paid 9000 for the car with 63,000 miles on it, and if I (try to sell a car with a bad tranny) sold it and got another used car...I had no guarantee on it's transmission. So, I bit, and one forgets, that as soon as the money is spent...you really don't think about it, and now I have a brand new transmission, with a guarantee...and I'm driving a gorgeous titanium jag with a black interior. Now I use the auto speed thing when I get on the freeway, set it and forget it....saves tickets, my unusually sensitive foot, saves gas. Great habit to get into. When I go on a big rise on the freeway, though I notice that it's more efficient for me to get out of auto speed, (or whatever it's called) as the tach shows too high revs on the hill climb, but drops down to 2 or less when I go back to using my foot on the gas. At 100,000 miles one is supposed to change plugs on a 2000, and when they change them, they are supposed to look at the chains.
By the way, when a 2000 XJ8 trans. starts to go, it moves into a special zone...I believe it's the third gear called something like limp home mode. The trans light will come on, or probably just the check engine light. Good luck...I say, change your transmission...or get a 2000.
So my question is - does clearing the codes really help, and does this type of shifting problem mean the transmission is going?
At your mileage, it's to be expected. You should only be using a jag mechanic.
Im so close!! Anybody out there that can help? Thank You.

when you get some where safe, take the shift indicator off. facing first, then shift indicator. You will need to put the car in neutral with the emergency brake one. to get these parts off but its simple to do-take your time. Get a strong light, look on the passanger side of the center counsole for the actual shifter cable: is it intact? firmly in place? You could shift into what would be park to see what happens. I'll guess that you have a broken neutral or rotary switch. Both are easy to replace.
Let me know.
Three weeks following service the tranny dash warning light comes on and tranny clunks into the lower gears after the car warms up (in about 15 miles) My last service man tells me it may be the computer which only the dealer can check. The car was purchased at and serviced by Jaguar of Darien in CT but I am now in Florida and the local Jag dealer on Merritt Island tells me that he does not have the equipment needed to perform any diagnostics on this car. Any one know of a reputable Jag dealer in Melbourne Florida area or nearby that is qualified to service the transmission on an old XJ-12. Any comments would be weclome I have been fleeced by $2,700.00 so far with this problem
You could hook up to alldata and get some positive answers if you are mechanically inclined. They are pretty good source for info. You could get parts used from jaguar heaven in california. I've used both these companies and I have no complaints. Good Luck, I hope this helps.
WOW i don't want to scare you but this seems creepy from what you said.
YOu can fit a taurus transmission in that ford engine (I think) but you should bring some reinforcements with you if you aren't mechanical and get some answers.
Good Luck!
Why don't you call John up, tell him andre referred you, and ask him a couple of questions?

i've only had one diagnosis and they said i need to replace the transmission but i feel if its mechanical it would jerk every time i came to a stop... am i being paranoid or does it sound electrical?
please feel free to email me at itsmepierre@gmail.com if you have an opinion or advise... :sick:
Out here in south san francisco, they rebuild transmissions, and the rebuilt ones are supposed to have some parts that do away with some plastic parts that were prone to failure. I'm very lucky to live in san francisco, whre I have about four jag shops to choose from, but have settled on John's Jaguar...very close to my house...and I get to know the mechanics, as opposed to british motors, which keeps it all upper crust and mysterious. I bit the bullet on my transmission, but then again, I bought my 2000 XJ8 for 9000. Total transmission and shifter bill was around 5 grand.(Trans is around 3000, then you add labor, etc.) I resisted the fix for a while until it hit me, that instead of buying another used car with an unknown lifespan on it's trans, I fix my car, now have $14,000 invested in it, and I'm driving a gorgeous Jag ( Titanium with black Leather, and more wood than they have in the new ones) with a brand new transmission. First thing I did was drive it to San Simeon, down the California coast for a week.
I have read a lot of entries on different sites and the common theme seems to be that many issues are being misdiagnosed.
Any feedback would be appreciated.

I also got the limp home bit, and had to change my transmission and also some parts connecting to my shifter. No way out of it, and it happened in the high 60 thousands. A rebuilt transmission is supposed to have better internal parts...some of which were plastic, and now metal, I believe. I spent 5 grand, but now have a new trans....a good deal compared to trying to get rid of the car, and buy another used car. The ladies love the thing...I'm sorry I do not know what a throttle body is, but I recommend you call John's jaguar here in san francisco, and ask about it, and frequency of problems with the 2000 XJ8. They are great guys...and do great guaranteed work.

I presume that you would like to know how my situation turned out.
I took my 2000 XJ8 with about 61,000 miles to the dealer after it went into limp mode several dozen times. They told me that the Throttle Position Sensor (TPS) needed to be replaced. On my XJ8, this means a $3,300 repair because the whole Throttle Body assembly has to be replaced, not just the sensor. The dealer would guarantee the part and the labor for one year. I asked them if the part could be re-manufactured. They said no, and that's when I told them that I found a company in the North East that would take my part, repair the TPS module, and send it back to me with a lifetime warranty for a $400! And that company guarantees that my Throttle Body assembly will be finished in two business days. The dealer did not seem to understand that I would gladly due without my car for about 10 days if I could save $2,200. The labor to take the Throttle body off, ship it, put it back on, replace a wire harness, and test everything was $700. So about $1,100 versus $3,300.
The dealer was reluctant to send the part for re-manufacture until they found out that they already buy their Anti-lock Brake Sensors (ABS) from the same company. They claim they did not know that they "did" work on TPS modules.
The car drove like it was brand new after the repair. Then a couple of months later, my car went into limp mode One time. I called the dealer and he said it might need to be done again. I could not believe what I was hearing. The only good news was that the dealer would not charge anything, but I would be without a car for more than a week.
I then decided to go to a non-dealer auto repair shop that works mainly on Range Rovers as sort of a second opinion. They could not replicate the problem, nor could I. They researched the Jaguar tech bulletins and thought the problem was more likely related to something in the gear shifter (center console area) or where the wire connects to the transmission, or maybe an ABS sensor. So, they ended up cleaning a little corrosion off the connection at the transmission, drove it a fair amount, and charged me a $95 diagnostic fee.
I have not had a single problem with the transmission going into limp mode since then! But there's one more thing that may have made a big difference. I have Stopped using the left side of the gear shifter that allows you to drive your Jaguar as if it had a manual transmission.
Do you you ever drive your Jaguar in this manual transmission mode?
You may also want to see if there is a Jaguar "club" in your area. If so, ask them where they take their Jags for service.
I hope this was helpful.

You need to first find out if a rebuilt transmission has the updated parts, like mine does...the failure of the 2000 tranny is common around 70,000 miles. A rebuilt should have newer parts that do not fail like yours does.
I bought my car for 9 grand. had 64000 miles on it. had it for a year, then spent 5 grand on parts and labor...it was a tough decision, but made sense..as selling a jag with a bad tranny is a nowhere deal, plus now having a jag with a new tranny at 75000 or so, is much better than buying a used car for five grand and dealing with that. ABS module error light happened to me...british motors wanted 2 grand to fix it. Some guy on ebay fixes the part for 60 bucks...you mail it to them....you have to find a way to cover the abs unit when you send the top half to this guy....and hope that's your problem. You also have to see if no abs computer at all in your car affects anything while it's being worked on. Ask yourjag guy to show you the abs unit...it's way up front on the driver's side....ask them to open it to show you the thing....and watch carefully....you don't want dirt getting inside there. Take a picture of it then and there, and then see if the pic on the ebay guys page looks like your part. I never followed through...I drive with the abs light on all the time.
Don't ask. I can direct you to the ebay abs guy....CAll John's Jaguar in san francisco...he's a good guy.
Thanks for any inputs that you might have.
I am about to buy a Jaguar 2000 XJ8. I have a few questions:
Does every single one XJ8 experience transmission failure that requires a rebuild? Should I expect to spend $3000 every 50000 miles for a rebuild? Thanks.
So if I buy a $2000 XJ8 from those years now, I probably expect to get about 10000 miles of trouble free driving and after that it would be $10000+ in repair to fix problems, rebuilding transmission and rebuilding engine must be accounted for (in some cases several times)
Went to Just Answer to get a mechanics opinion about my 2000 XJ8, they billed my credit card $40 then said my email was already on file (never been on that site before) and didn't match the password-they reset the password and when I tried to use it .I got the same message. Never did get an answer but, owe Visa $40 for the 'visit'.
The transmission has always leaked a very tiny amount of fluid, but it's working fine. Right now I think it needs some tranny fluid and the brilliant engineers at Jag have made it very difficult to check the fluid (stupid move Jag).
I have had only one other front suspension issue that was warrantied long after the warranty expired.
Here's a Chart of the various trouble codes on your ZF transmission
The second time I was going up a rather steep hill, the same clunk happened and I lost all drive, because of the incline I couldn't get off the road, but I turned the car off, restarted it and again everything was back to normal.
On both occasions gearbox fault came up on the dash. Does anyone have any ideas before I take it to the shop?
FYI, your car uses the ZF 5HP24 transmission, in case you want to dig into it further.
Here's some technical information for you:
http://www.thejagwrangler.com/uploads/8/0/2/8/8028029/jaguar_xk8_transmission_control.pdf
In addition to meeting all the OBDII diagnostic requirements for fault storage and freeze frame data, the
TCM also has its own fault memory and diagnostic functionality for non-emissions related failures.
For each and every fault, the TCM stores freeze frame data which is tailored to the specific failure. For
instance, for electrical failures the supply voltage at the time of failure would be recorded, Three items of
freeze frame data are stored for each fault.
The TCM also stores the fol€owing information for each fault (and keeps up to date):
1. How many times the failure has so far occured
2. Is the fault present now?
3. Is the fault intermittent?
4. Has the diagnostic test for this fault been completed in this drive cycle?
5. Fault type (short circuit high-low, open circuit, rationality check etc.)
This information is designed to aid quick and efficient rectification of the failure.
All the fault information is kept in EEPROM memory so that, even if the TCM is removed from the vehicle,
fault information is not lost.
