[x-type] X-Type Transmission Failure

(DevonS) #1

Hello all,
I have a 2002 X-type with 58,000 miles on it. My wife was
driving it to work and came right back home telling me that it was
revving to 4000 RPM when she was going about 30 MPH. I drove the
car and found that it would shift gently into 4th gear and then
slip if you gave it any power. After a few weeks researching this
and a $8000 quote to fix (over the phone) from the Jaguar dealer. I
found that there is a common failure of a piston that cracks and I
was fairly sure this was my problem…To make a long story short,
I fixed the car in about 4 hours without removing the transmission
from the car. If anyone has a similar problem and would like to
know the steps to fix it, plese post a reply and I will respond.
Have fun!

Well…there’s a cover on the left end of the transmission that
can be removed while the transmission is in the car. I had to
remove the battery and the brackets that hold the battery (this was
mostly to make things easier, probably not really necessary), the
lower plastic cover under the front bumper (not hard, just about 25
screws). I removed the left front tire and took the two front bolts
out of the sub-frame that holds the suspension, steering, etc out.
This let it drop a couple of inches down. Then jacked up the motor
for support and removed the large bolt on the left motor/trans
mount near the left shock tower and the round upper bar going to
the motor from here - two 13mm bolts. Then I lowered the engine
just an inch or two and this allowed me to get right at the cover
behind the left wheel well. It has about 13 or so 12mm bolts and
two 14mm ones with o-rings. The whole cover is under spring
pressure for a way so I removed the bolts evenly to keep it all
strait. Once, you remove this cover, the drum housing the faulty
cylinder is right there, just pull it off. It contains the reverse
clutches and the direct clutches. Remove the two rings that hold
the clutches in and take them out. You have to depress the center
cylinder and remove a retainer ring to get the pistons out. The
large aluminum drum is the one that cracks and it’s almost
impossible to see - very very small crack. Depending on how much
the car was driven you may have to replace all the clutches in the
reverse stack - since the piston won’t allow any pressure on the
direct clutches I’d be surprised if they would need to be replaced.
Assembly was easy and it all went together easily, you just use
silicone (very sparingly) for the gasket as was original. Then
Refill and check the fluid - which is a little tricky but not that
hard. I used the Castrol Import Multi Vehicle transmission fluid -
$3.99 / quart and used about 8.5. This meets the Shell spec. for
this transmission, I’ve heard the fluid $40 / quart from the
dealer - ouch! It’ really not bad if you go slow and keep
everything as clean as you can. I purchased the JATCO JF506E
rebuild manual from ATRA (I think it was $25, but didn’t really use
it except for reference/pictures) and I have the Jaguar JTIS which
helped too but the pictures are vague. I hope this helps someone
out, I really love this car and there doesn’t seem to be too many
problems in the 2002’s but was a little worried how much this would
cost to fix - total $210 including fluid - I also replaced the
thrust washer that is between the cover that you remove and the
drum, it was a little worn looking. Good luck. I may sit down and
write step-by-step with pictures and details in the future.

Great description Devon. I do hope you follow up with a step by step and
pictures guide. Pardon my ignorance but is this the auto or manual gearbox?

Devon,

An excellent post! When I look at the transmission the valve body
and (as you describe) the main clutch pack can be removed without
removing the transmission from the vehicle. This makes the
transmission very repairable. So why then have owners been gouged
with the ‘‘replace with new’’ dealer tactic every time there’s an
error code on the transmission? Where did you get the transmission
parts?–

Anthony,

Dealers are simply following processes established by the factory.
If you look at JTIS and review any of the diagnosis sections, all
diagnoses end with ‘‘Replace the unit’’…even the engine; and this
is for almost any repair other than gasket and seal leaks. Keeping
in mind that the diagnosis and repair processes were written with
factory warranty in mind, the factory benefits financially in a
number of ways:

  1. No worldwide parts distribution and management below the unit
    level
  2. Tech training is less expensive.
  3. Dealers do not have to carry huge parts inventories.
  4. And the biggest one, after the car gets old enough and out of
    warranty, repairs become so costly and prohibitive that repairs
    exceed the value of the car, so it is easier to justify trading it
    in for a new one. Jaguar especially likes that because they need to
    keep selling new cars averaging every four years of ownership.–

Steve,

Sadly, you’re right. But that’s how you put yourself out of
business because nobody wants to buy your cars new or used. I
guess for those of us who know we can take advantage of some
exceptionally low prices for these cars. We then either fix them
oueselves or find a good independent shop.–

Exactly.

As enthusiasts, wanting to keep our cars running well for a long
time, we’re not Jaguar’s favorite customer. We’d put them out of
business if we only bought a new car once every ten/fifteen years.

They REALLY hate me because I never buy new either, and the service
depts in dealers hate me too because I do all my own mechanical
work unless its free under warranty.–

Hello Devon. I am experiencing the same exact problem you had. I was wondering whether there is a email you can be reached at to discuss this further? I want to compare what I’ve found and see whether the parts I plan to buy are the correct ones. Thanks.

Please send me the fix, would appreciate very much.
