Jaguar XJ Transmission Questions

    My 1995 Jaguar XJ6 began having a transmission problem in the last few days. It feels like the transmission is slipping as the car feels like it's bucking a little or like the transmission is grabbing and then periodically letting go for a second. No lights have come on and the fluid is full. I live on a hill and once recently I had to pull the car out of park a little harder than normal and heard a little clang, so I don't know if that has anything to do with it. I didn't know if there was some adjustment it needed as replacing the transmission makes no sense in a car worth under $5000. The car has 135,000 miles and I believe it's the original transmission. Any suggestions on what to check?

    Well you'll have to have the transmission diagnosed to see if limp mode is from an external or internal problem. If it's from an external sensor or control unit it may be worth fixing. If it's internal, the car is probably not worth repairing, you are right. You could buy a clean, low mileage 1990 XJ6 with a good transmission for less money than overhauling your transmission, which is at least 20 hours just for the labor.

    100K is not great longevity for an automatic transmission but it's not premature either. The world's best warranties from the world's best cars don't offer more than 100K, so if Rolls Royce or Toyota or Mercedes apparently doesn't think a transmission should go over 100K, i don't see why Jaguar owners could hope for more. One might expect 150K but more often than not, it doesn't turn out that way for most car owners.

    Options? Spend some $$$ on a diagnosis and make your final decision based on that. There is a complete diagnostic step by step for this transmission available to any competent shop.

    Engine missfire would relay the same symtoms. Age of wires and plugs?

    Actually, you hit the nail on the head. It was a bad coil, which was causing a misfire. The shop replaced the coil and plugs, now no problem. Always take it to a Jaguar mechanic though, the first shop just took it for a test drive, then said the transmission was bad.

    Happy to know you have it fixed. The XJ is an admired motor car. :)

    Since you seem to know a lot, how easy is it to replace the bulbs that make the clock LED's work, as they are not readable at this point. I know I have a watch, but I'm on the go a lot and a working clock woutd be nice.

    Is the brightness dependent on a dimmer or reostat that varies the volume of light illuminating the rest of the dash? If so, turn up the dash lights dimmer to it's brightest setting and see if it is connected to the clock.

    Jag transmission problems? Contact immediately, the NHTSA hotline center.(National Highway Traffic Safety Administration.)
    Either e-mail NHTSA Hotline@telesishq.com or call 1-888-327-4236.
    They will take your complaint seriously.
    If they have enough complaints, they will open an investigation and determine if a recall should be done.
    Sept 30,2008 my 1998 XJ8 started balking and the transmission fault light came on.The car did not want to move forward, but very slowly. in several miles, there was a loud thuuump.The car did not want to accelerate. I had the car carried home on a flat bed truck.
    I googled transmission fault Jaguar and came across several sites with a multitude of complaints from Jag owners about failed transmissions.
    I called Jag Corporate and they claim not to have any complaints about transmission fault problems. Jaguar stated that the owners of the vehicles with transmission fault problems probably do not service their cars. I stated that is simply untrue, that you cannot say that all the Jaguars that have transmisison problems have owners that do not take care of their vehicles.
    I reminded him that I had called Jaguar and complained about 3 years ago that my Jaguar would suddenly lose power on the interstate and I was fortunate that I was not killed.It happened about 6-8 times and Jaguar told me that they had no other complaints about the issue. Well, here we are almost 3 years later and 6 months ago they issued a recall for the Throttle Operation which in "EXCEPTIONAL CIRCUMSTANCES" could cause the car to lose power.

    I filed a complaint online with consumer.com and the NHTSA.
    NHSTA recorded the information today with a case number and will have an investigator review it within the next 48 hours.
    I called a transmission shop and was told that the drum breaks and the metal gets into the transmission and that it is a common problem for Jags.

    SO IF YOU OR ANYONE THAT YOU KNOW HAS HAD TRANSMISSION PROBLEMS, I URGE YOU TO IMMEDIATELY FILE A COMPLAINT.
    Good luck . Cin2
  • I have an 05 xjr (silver) with the clear comeing off in spots.......Jajuar says the car is just old!!!!

  • Sorry new on this site,But got to respond to this one.....I did spend $$$. 123.19 Jaguar dealership Jax Ms. I was told by a jag tech all i needed was a new Transmission.7200.00 + tax.Allso was told this is a sealed unit..could not be serviced......As it turned out.... not so.Had a crack in the trans pan (plastic).After three weeks of looking and calling........and $$$..I fixed the transmission ...I replaced the pan some fluid 500.00 give or take.This was after i spent 700.00 give or take finding what was wrong.And wz up with this trans fluid???? 69.00 a lit.....(05 xjr). Jaguar has been doing this for years. Everytime i say this is it,Jag has got to go......But like my pretty young unfaitefull wife,after a day or so i forgive.Guess i don't care for change.

  • HELP 1994 XJ6 sedan, cherry condition, 129K miles, I have gotten thru many of the problems I read here in other categories, but my trans problem is a bit scary. I am having "slamming" or "bumping" at shift points both accelerating and decelerating on occasional start ups. Only occasional. (scary compared to normal shifting points because it snaps my neck a bit when it shifts upward while accelerating) and the transmission fault light appears, plus the brake fault light appears each time the brake pedal is pushed, signaling the likelihood of an ABS problem. I had the brakes all renewed stem to stern and no problem exists with them mechanically, but could be electrically. Was told to "forget" the brake fault light, so i ignore it, but it comes on each time i press brake. This trans problem has occurred approx. 5 times in the last couple of years and goes away when I shutdown and re start engine. Shifting gears does not help, only shutdown. I suspect electrical or computer programming issues, but not certain. I saw one message here that put the two problems together. Any help would be appreciated. Nobody in this South Louisiana area works on Jaguar transmissions except perhaps the dealers in Baton Rouge and New Orleans, which I would like to avoid as long as possible due to horror stories. I will travel to other states for quality service and workmanship. Thx, Don [OMEOMY]
  • Hey wojcik!

    Where did you read that other post? I would like to go there sometime. Your post here gives me the idea that i have one or more bad ABS sensors, considering i replaced all mechanicals on brakes and the brake fault light still comes on. Could be the mechanic that replaced brakes caused the ABS sensor problem, who knows?

    Next step is to find a great tech and see about ABS function and replace all of the sensors if necessary. Then on to my tranny "slamming" in every shift point problem. thanks for the start in a direction wojcik! any other help is certainly appreciated.

  • I have a 94 XJ6 in great shape because I have put thousands of dollars into it. 4000 alone in the paint job that had to be done, plus all the mechanicals. But, the electrical and computer systems continue to befuzzle me. i am currently having an intermittent transmission problem where at the shifting points, the shift "slams" at the change, so much so that it sounds like it will damage the transmission.

    Here is one thing i did after putting 3 new expensive batteries in within months. I suspected that what was draining the electricity from the new powerful batteries so fast, was what is called "parasitic drain". This can be from more than one source, but i suspected the security system. I found out that it is not advisable to disable the security system, so i installed a "master switch" just under the battery. Expensive, yes, but the battery drain and replacements stopped now for over a year. That heavy duty switch becomes an excellent "security system" in itself. This is only one example of the problems to be uncovered and fixed with this 94 XJ6. Like so many Jaguar owners, i keep putting the time and money into her because i love that car. I wish someone on this CarSpace forum would tell me of their great mechanic/tech. I would call and drive there immediately with my exotic problems. (not so exotic with Jaguars, i have come to believe). Oh and i got the electrical service man that put in my new alternator (Mikes Alternator Shop), put that special "master switch" in. Hard to find these people to help. Good Luck with the 93. OME_OMY Don
  • :shades: My search is focused on looking for a good or great Jaguar mechanic/tech. Particularly electrical/computer problems and enhancements. My experience with the Mobile Alabama Jaguar dealership and others is that...The techs that are great for newer models are not old enough to be great with my era Jaguars...1994 XJ6

    I will travel long distance to any southern states particularly to find such a tech and service facility. Texas, Louisiana, Mississippi, Alabama, Florida, Tennessee, Missouri, Arkansas for example. Do YOU know one? :surprise:
  • hey tjb
    we have almost the same problem. i have had this intermittent problem for a long time, over a year. let's talk more.
    i have a 94 XJ6. mine is in great shape otherwise. the trans light comes on, mine starts out from the beginning with shift point "slamming" and snaps my neck, and could be causing trans damage. when it happens, i then stop, turn the ignition off, start it up again, and all is fine again for quite a while. i have not had anything done by anyone. i see by other posts here that there may be a connection with my ABS brake light coming on, i am going to investigate the possibility of bad ABS sensors on one or more wheels, replace them if necessary, and investigate perhaps a bad ABS sensor wire, and go that direction first. Then see if that stops the intermittent craziness of the trans light coming on with the slamming problem. :( :(
  • Hey Don, Greetings for another South Louisiana Jaguar Owner. I have a wonderful mechanic here in Lafayette that is a Jag expert to say the least. His name is Bill at Bill's Garage (337)988-4200, I sure that he'll be able to help you with any of needs. If you're in the Northshore area a good friend of mine has a guy that works on her and her family's vehicles. Ironically both mechanics used to work together at Paretti in New Orleans. I know Bill started off in the British Leyland days so he has many years of knowledge. Lemme know if there's anything else I can do for you. Best of Luck! ~ BEN
  • I have a 1990 Jaguar XJ^ Vandenplas. I've had problems with starting the car, need to change the battery. The last time I was able to start the car the transmission light came on, the one that says the motor is in "limp home' mode. The car runs perfectly well and has no mechanical or transmission/shifting isssues. The light won't go off. I checked the fuses and they are fine. I heard there is a simple solution to this, but forgot where I saw it. Does anyone know how to turn off the trans light? Thank you, Anne
  • First i would try... disconnect battery for a min.Next just drive.......pull over .....turn motor off and restart the car.A broke motor mount or trans mount will cause the light to come on.Car may need a tune up.I have owned 20 or so jags over the past 8 yr and they all done this one time or another.May want to baby it a little from a dead stop.

    Optional Information:
    2000 Jaguar xj8 4.0

    Already Tried:
    well it made a clunk noise when it was down shifting to 2 gear it made that noise a few times then when i came to a complete stop and then go forward it felt like it just slip and the light came on Transmission fault so i shifted to 3 gear and it did move slow but it it took a few seconds to get up to speed there is no noise coming from the tranny
    thanks
