No really problems. There is a recall out for a programming issue. Other than that the cars has been great.

I have a 1998 XJ V8 vanden plais. Last spring at 80,000 I had a rebuilt transmission installed from a transmission shop. A rebuilt transmission cost was $3200, while a brand new transmission is $7000+ from dealer. Rebuilt possibly can last another 20-30,000.
 
Good luck.

washing the car and limping home by fish62

I have a 1990 xj40 that has a 4.0 liter that run great and has been fully tuned. the nagging problem that I have is that after washing the car the transmission jumps to limp home set for about a week to ten days and the works fine. It sounds like water under the dash when I turn right or left. Did the previous owner/mechanic leave a plug out?? or is there something I can do to prevent this (other than driving a filthy BRG jag???)

You could try covering the fresh air vents under the wiper blades with clear plastic and tape while you wash it. If that works, then you know you have a leak through the firewall under the wipers, possibly from a clogged drain in there. What happens is that the drain clogs, the water builds up in that basin like a fish tank, and then sloshes through some plug or cable or opening in the firewall...the firewall was not intended to be waterproof.
 
So clean the drains out and that might help you.

Check the connector on the transmission(driver's side) if it has the rubber boot, or check for the connector's connection cleanliness, check pins if they are not corroded, use electronic parts cleaner. Check for trans mount, if it's gone the trans will move more then it was designed and can cause connection problems.

Yup.
 
I have a 2000 XJR which I bought in 2001. To tell the truth, it has been an excellent car. However, last month, the transmission just started to disengage for no reason. I had a few other error messages crop up (a rear wheel sensor was going at the same time, which disables traction control and ASC). I have twice now gotten an incorrect gear ratio error that lets me limp home; when the car is restarted, no problem.
 
It is QUITE a problem when you go to accelerate on the highway and the engine just revs. Flipping to a different gear, or in and our of neutral, does nothing. Not even an error message most of the time. When the car slows down to 30 MPH, it re-engages with grace and ease - not a slam jerk or anything like that.
 
So far, the Jag dealer tried to sell me bushings and shocks (don't car if the transmission doesn't engage), AAMCO says the mechanicals are OK, and I'm out $1500 of various 'repairs'. The ECM has thrown a transmission error (incorrect gear ration), but the TCM doesn't have that error. Seems like I have an electrical problem somewhere, but WHERE!!!
 
Any ideas?
 
Regards,
Louis

Your message has a real clue in it. Read a post (elsewhere) about a guy whose XJ would dissengage and he got so he could tell it was about to do so. Went thru 2 tranny replacements and countless other things until a true technician spotted a faulty ABS sensor on a rear wheel---the engine management system recognized the (erroneous) signal as a catastrophic condition and disengaged the transmission! I'm simply repeating the story, but it looks like your tranny problem may be little more than the car trying to avoid self-destruction that is being suggested by the ABS sensor.

XJ6 Problems by cartroubles88

I have a 93 XJ6 sedan and, at the moment I think I am having transmission problems. I'm not sure and I honestly won't be able to aford to take it to a mechanic to even look at it until next week. The car is making whining noises and every now and then I hear like some liquid sloshing around (sounds like it's behind me but I'm not sure). Idk why it would have problems it's only been driven 77k miles since my grandfather bought it in 95. The car also has had plenty of trouble with the battery and circuits. Can anyone help tell me if they are having similar problems and how they fixed it or if anyone knows this situation well enough to advise.
