Sounds like your mechanical linkage is loose. Try this: on the gear indicator for the j gate there is a plug with a star indent on it up by park. unscrew that plug, below it is a latch that keeps the car in park-or the shift lever in park. get a skinney driver put it down that hole and push down to release the park lock. Move the shifter to neutral and start the car. If you need to move it do it now, using 4th or 3rd. on the j gate.
 
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.

Thanks. I finally found some time to work on the problem, and you were right about the mechanical linkage being loose. I was able to get the console apart far enough to check the cable, and it looked fine. I then got under the car to look at the other end of the cable and found that one of the 2 bolts holding the cable bracket to the transmission was missing, and the other was loose. A new 8mm bolt and a few drops of locktight and I am back in business. Thanks again.

Good for you! How much would that have cost at a dealer? $2K minimum. Congratulations

My 95 Jag has 55,000 miles and I have had two tranny services (Non Jaguar shops)The internal wiring harness and selinoids (sp?) were replaced at both times and on last service the Tranny was "rebuilt".
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

It could be anything but a major mechanical problem. Because it acts up after it warms up it could be the throttle needs adjustment/ cleaning.Or the speed sensors. Does it have fluid? its simple to clean the throttle, take the air filter off look down into the throttle and clean the carbon out. DON"T take it apart. You might get lucky!
 
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.

#67 of 94 XJ8 with rebuilt transmission by kjpesq

My 2004 XJ8 with 30,000 miles on it has been in the dealer's service bay for nearly 6 weeks; I couldn't find an independent transmission specialist who would take it. I've been informed that the dealer installed a rebuilt non-Jaguar transmission (I think the delay was with their not being able to get the Jaguar transmission). How much should I expect to have to pay for this? And why do they tell me that the car won't be able to pass state inspection until it's been driven several hundred miles? Why do I feel I've been had.

Somethings not right! Why don't you know the cost? they should have given you the estimate and got your permission before they started? a non jaguar transmission?
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!

I'm in san francisco...obviously a pretty good place to get jag service.. But I stopped using British Motors, and now use John's Jaguar in the Mission district. It's a very small jag service and repair shop, and they get it right. The owner is there...and he's a classy guy. They got my rebuilt 2000 XJ8 trans from a center in south san francisco...It's true one isn't always ready to grab..I got a bit lucky...so the work took about four days. Guaranteed for one year...doing just fine so far.
Why don't you call John up, tell him andre referred you, and ask him a couple of questions?

#70 of 94 transmission problems by itsmepierre

Feb 28, 2010 (11:28 pm)

ok i have a 1998 xj8l... when i start my car and put it in drive it will idle like its in neutral then it jerks very hard.. and starts to go.. it will not accelerate like normal until i'm over 30mph... after that its cool... now i can stop and go with the same slowed acceleration but every time i cut off the car and restart it... it jerks into gear..
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 itsmepierregmail.com if you have an opinion or advise...

The shifting mechanism can also be a problem, not engaging properly. When I needed a new trans, I also needed that assembly too. Funny, when they were done, some linkage to the drive shaft, (New part) failed...Free replacement done. How many miles on your car?
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.
