    Re: jaguar xj8 gearbox fault problem

    Can you give us a little more information? ie. will the car drive, or is the gearbox noisey etc. Did it just happen all at once, or get progressivly worse?
    Could be as little as a bad electrical connection, or low fluid etc

    Re: jaguar xj8 gearbox fault problem

    sorry,
    The car was running great then at a stoplight it wouldn't move then it jerk real hard and the gearbox fault code came up. It will go into reverse no problem but won't move in drive until It reves up and then jerk into a limp mode. transmission don't make any noise it is real quite. the car has 65000 miles. If it was a bad transmission it would have been shifting badly right?
    Thanks

    Did you move the gear selector at the stoplight, or leave it in drive?

    Do all the gear selector indicator lights come on as you shift the gear lever?

    Re: jaguar xj8 gearbox fault problem

    yes, all the shift lights are working fine. Everything is working like it suppose to except the transmission when you shift to drive it revs up and then jerk and go into a limp mode which seem to be high gear.

    You will need to have the fault codes extracted to determine the problem. If you can post the codes on here I could look up the cause from the manual. Autozone will scan the system for free.

    Re: jaguar xj8 gearbox fault problem

    I have an 99 XJR and lost the trans last Oct after experiencing several issues with the trans fault light coming on randomly at start-up. The cost to have a new one or rebuilt was more than the vehicle was worth but I love my car. My trans guy offered to install a low mileage used trans at a reasonable cost so I opted for this and after 10,000 miles of trouble free driving, the darn trans light is coming on again only at start-ups just as it had before. As I've done in the past I turn the engine off andwait a few minutes and restart the engine and the light will go off and the car will run normally. The only other thing I have noticed is that the supercharger becomes disabled after an episode of fault light illuminating but returns to normal after a few start-ups. Could there be some external computer glitch causing the same problem and behavior with this second transmission? I have always serviced my Jag at the local dealership in Pasadena but I've become so frustrated with their level of customer service and nickel and dime attitude to permanently resolve this one issue in the past.

    Re: jaguar xj8 gearbox fault problem

    OK, all, thanks for help so far. Here is the status:

    I took it to a transmission place that has a good rep, and they pulled the code 1722.

    Fluid was full.

    Here are some other diagnoses: When you start the car, it surges forward in P. Also seems like there is no 1st gear, and it whines until you get fast enough to hit second gear, and then it goes fine.

    I found a place that sells remanufactured ZF5HP24 transmissions for $2495.00 door to door, shipping included. (Coleman Taylor out of Memphis.) It includes a 2 year, unlimited mileage warranty. (or a 3 year, 75,000 mile warranty for extra $)

    The good news is that I have an extended service insurance contract that covers up to $3000.00 per visit for a maximum of $5,000.00 for the life of the car. Since the car has been babied, and it only has 57,000 miles on a 100,000 mile transmission, I should be good to go, right?

    Square Trade is the company that I purchased my extended warranty through. Anybody heard or had problems through Square Trade?

    Hopefully it works out OK. I am just sick about the Cat being dead... Hopefully this is not it's ninth life, and it will come back good as new!

    I'll keep you posted.

    Again, thanks for all of the help so far

    Re: jaguar xj8 gearbox fault problem

    Let me join the crowd.

    '98 XJ8L around 95K miles.
    Just driving down the road about 35 miles an hour...big clunking noise and gear box fault light came on.

    The car would slowly move from a stop and then run well passed about 30 miles an hour. Straight to the shop with it.

    Sounds like a new transmission?

    Re: jaguar xj8 gearbox fault problem

    Here's the latest...

    Transmission was shelled - the Clutch A and C destroyed itself...

    Apparently from my transmission re-manufacturer for the ZF5HP24, this is not an uncommon fault.

    There is a new part number out, that has a snap ring that prevents the clutch from shelling itself..

    part number 1055240074

    Problem is, the damned krauts at BMW are on strike, and the clutch is on national backorder...

    They (BMW) have been saying "2 weeks" for the last six weeks to get the part.

    Any help would be appreciated...

    Do you get the "TRANSMISSION FAULT" on the dash board...if so...get an OBDII computer to see which codes you get...and post them...
    we'll take it from there...
