#46 of 95 Transmission Issues
May 03, 2009 (3:01 pm)
I have just bought a 1998 Vanden Plas with 98K miles. I noticed the "transmission fault light" came on as I pulled up at home. I am not quite sure how to deal with this as I do not have any prior experience with Jags. One thing is obvious - I need to get to a mechanic. Please I will appreciate any advise from experience Jaguar owners. I will also appreciate recommendation on good jaguar mechanics in the NJ area.
Thanks in advance for your help.

Any luck with researching with using a different transmission?

using different tranny...You gotta remember that a jag computer is hooked up to the jag tranny...and good thing it is...So, I doubt that you can put another one in and have the computer be happy.

Tranny work is guaranteed for around a year. IF you get a new rebuilt one, ask about whether or not the trouble with the old one has been updated or not in the rebuilt one with better parts, etc. Also, the coupling for the trans to the engine was replaced on mine, and it just failed...New one put in free last week, Coupling lasted me two months.!!! You may or may not need a gear box also, if it is sloppy. Sorry, can't help you with new jersey....But look for British motors repair before hitting something else.
Hope you got a decent 10 grand or so price for the car, as I bet you will need to spend about another 5 - 6 grand in the next two weeks.

My light has not come one. I have a 2002 VDP with 59,000 miles. It seems to downshift on its own once in awhile. The last two times car shook violently and made a loud noise. Otherwise it runs well...no leaks whatsoever. Could it be the solenoids? Should I have it diagnosed by Jag dealer?
What atf can use besides the expensive dealer fluid? How much does it take?
What is the name and number of the South SF tranny place? I live in Santa cruz..
All help is greatly appreciated?

I'm a real amateur at this..but don't wait for answers here...Take it in. Hey..one of your plugs is going bad, or, maybe oild isn't getting up into the engine due to a clog in the line that goes down into your pan...maybe the coupling to the tranny is starting to wear out...or the tranny fluid is low...or the tranny is going....
THis year I replaced my transmission, the shifting assembly, also the coupler from the engine to the trans. GET this the new coupler lasted 30 days...I started feeling a roughness at certain higher speeds....I knew something was wrong..didn't wait, and a new coupler was put in for free, as I got a warranty for a year for all the stuff.
So, check your trans...linkage, engine...now...

The south city trans place is not a repair place. I got to John's Jag service on Valencia St. between 18th and 19th, I believe...740 Valencia 415-829 8480

The verdict unfortunately is in. Went to change
the fluids (almost 60,000 miles) what we found out fluid was
greenish (from what I understand this this is the expensive
stuff) but it had a bronze residue to it. The magnets had
metal shavings to it (which is expected) but the bronze
large deposits in the pan are a sign of thrust washers
(according to my mechanic).
Soooo now for a course of action:
1. Getting prices from bay area jag places for rebuilt
tranny (trading my in as a core)
2. Bringing in my tranny and have mine rebuilt
As I see it I need to find out cost and LENGTH OF WARRANTY.
My mechanic will charge me about $400 (6 to 8 hours) of
labor for removing and replacing it once it is rebuilt. He
replaced head gaskets on my '95 xj6 (for about $600) and it
is running great.
One of the quotes we're getting tomorrow is from my mechanic
that services the other family cars who works for AAMCO.
They have a lifetime warranty (also 90 days, 36 months,
etc). So the big question is how much this lifetime warranty
will cost, how much a 36 month will cost compared to shop
that specialize on jags (mercedes, bmws, etc) warranty and
The jag dealer wants $7,500.
I would like to hear everyones idea on the above.
I'll get back to you when the quotes come.
This is a big set back but when I'm on the open road with
this baby ('02 VDP)...no comparison to any other car!

Have 1998 XJ8 - since the car was new, the transmission would not shift going up a hill until the crest of the hill. At the time, I was told that was normal.
Car has 99,000 miles, has been serviced always, but lately, and not always, the car will have a delayed shift as if it was going up a hill. It is better when the engine and transmission is warmed up, but still happens some time.
My mechanic cleared the codes, and it was better for a while, but it happening again.

My 2000 XJ8 shifts when going up a hill. But usually the case is that it shifts down. And we have some mothers here in S.F.(hills)
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.
