[xj40] Not my week

XJ40
#1

So far, this has not been my week… I got out of my car after
driving back from lunch yesterday to discover something I had not
noticed as I got in- I hadn’t looked as I was close to the next car
over, and hadn’t thought to- I found a basketball size dent in my
right rear quarter panel- just forward of the tail light. And the
outboard tail light studs were broken as well. Someone had hit my
car in the mess hall parking lot, and did not even leave a note. I
managed to remove the BFM and bracket, as well as the antilock
brain box, and pushed the dent back out- it tin canned pretty well,
other than a couple small dings, and the fact the quarter panel now
needs repainting. She still looks good at 5 feet and beyond.

So, on the way home today I took her in to get a car wash- covered
in road salt from the weekend, she needed cleaning. As I turned the
corner in, she felt like she had a tire spinning. Then, after I put
her in gear after paying for my wash, she would not move! We pushed
her clear, and I checked underneath. Nothing obvious. So I got up
and restarted her- and she moved. I drove right over my hand held
spotlight, destroying it. So I finished my car wash, and drove
home. Got almost there, and she stopped working right again- I
coasted downhill, while I shifted to neutral, switcher her off and
started her back up, and the tranny worked again. Got her parked
and called AAMCO.

Tranny sounded like it had a chain spinning inside when she
wouldn’t give power. Seemed to reset when shut down. She has had a
judder sometimes when shifting, maybe it finally gave. Any one
else have any similar problems? Happily she got me safely home. I
LOVE this car. Any other one would have just blown and duped me by
the side of the road. My poor kitty, wounded, did her best to get
me home, and succeeded.

PS- At least the Vanden Plas interior I replaced my XJ6 one with,
looks great!(My XJ6 interior looked great, just wanted a Vandy
one…–

hi have you changed your tranny fluid recently?? I had this
problem once with a th400 tranny. what was happening was the
pump was picking up the fluid along with all the gunge in
the fluid. this resulted in the filter getting clogged up
and the tranny not working. after switching off the gunge
dropped off and the car would drive for a bit longer only to
give up as soon as the filter clogged again. take the sump
of the box and change the filter in it. btw don’t coast yer
car yule knacker the gearbox.

Fluid and filter changed about 2 weeks ago- I change them every 15k
miles ± a few k. Sound started when the power transmission loss
was flt- came and went with it. Like a slipped bike chain.

AAMCO has torn my tranny down- Torque convertor is trashed, and I
am waiting word on the tranny rebuild itself, regarding what inside
is shot… Least I’ll have a new tranny when done!

First ZF transmission failure I have heard of so far. Is it the HP 22
or HP 24. Takes a lot to trash the torque converter from what I
understand and I would have thought you would have noticed some
malfunction in the lock up before it failed. Did the lock up work fine?
Just curious as I have never heard of a failure before and just want to
get an idea of any warning symptoms since mine has 200K on it and other
than an oil change has had no service.

As for rebuilding the inside, I would expect it would be mostly the
valve block needing new O Rings and gaskets.

Keep us posted if you can.

The word is in from AAMCO- about $2,800 in rebuilding… The basic
rebuilding is about $1,895 and the rest is parts- the clutches are
all shot, in all 6 (A-F) clutch packs, and two housings are
destroyed- due to metal on metal machining- worn down sprocket
teeth, etc. on the pack housings, due to the shrapnelization of
some of the interior parts. Luckily the planetary gear sets and
valve body are in good shape, as are the majority of items, other
than as mentioned above. One of the diaghpragm springs even broke!
And the spring retaining lip on the case it was on sheared off.

As to warning signs, she recently started shuddering at shifts- she
had done that previously, but a fluid and filter change had taken
care of that. I just changed fluid and filter when I changed the
fuel tank, about the 15th of January- and at that time cleaned the
magnets off entirely as well as wiped the inside of the pan clean.
It was entirely covered in shavings again, and the magnets were
described as looking like a ‘‘Sea Urchin’’- which, when I saw it, it
most certainly did. I looked over all the parts, and am quite glad
for AAMCO- I would hate to do THAT rebuild!

As to type, it is a HP22, with 130k miles on it. I have no idea
what the previous owners treated her like, but I put the last 35k
on it, and changed fluid & filter about every 15k miles.

g’day
I trashed a converter on a autommatic mini once. I was
slip-streaming in it and I guess that would have the same
effect as towing it. the end result was total destruction of
the converter, and it had welded itself on to the shaft.
it also had a horrible crunching noise.

Well, I decided I don’t want to trust a used trans- I already have
access to one, and decided against- who knows what issues it might
have of its own. The final bill from AAMCO had the following:

Reconditioned Service- $1812.72
Torque Convertor-(Exchange) 379.00
Assembly Set 405.72
1Qts Filter(? have to ask…)28.00
Filter 46.94(WAY too much- I can get them 1/2
that
Overdrive Direct Drum 112.50
Intermediate Clutch Drum 21.43
Intermediate Sprag 100.00
Support Center(double drum) 119.00
36 month/36k mi warranty 399.00

I was kind of upset to discover a $280 charge for rebuilding my
steering pump- I had asked them to replace a leaking o-ring on the
hose at the pump, and supplied the o-ring in a kit and told them to
just use the ones they needed, and return the rest- they thought
I’d meant to replace all the seals- 4 hours labor! Luckily, I
caught this before they did the work, and cancelled the job- I was
planning to replace the o-ring myself, when I get a chance, am=nd I
guess thats when I will do it.

And the car won’t be ready till Monday- one of their installers
called out sick. Supposed to be done today otherwise. Annoying.
