The transmisssion case on my 97 sable is cracked a the differential.
Although for the life of me I don't know how this happened. The car has
142K km (88K miles) on it.
1) Anyone ever heard of such a problem?
2) Is it possible to weld this crack and get more life out of the tranny?
3) I got a quote of $1,500 CDN (~ $1,000 US) for an R&R with a used one
with 82K Km (~50K Miles). (The quote for re-manufactured was $3,700 to
I think used is the way to go for a 7 year old car but would appreciate
anyones thoughts on any of the above.
As long as the interior isn't falling apart and everything else is in
pretty good working order, I'd say go with the new transmission. I hope
those prices he quoted include labor charges. I'm guessing that if
those are Canadian prices, then American prices would be $2,500 - $3,400
or so. Still, replacing both the engine and transmission is a lot
cheaper than replacing the whole car if you're wanting to keep the same
level of comfort and style.
I figure that most people must make a decision based on what they can
afford at the time they have the problem. I had a situation once in
which my truck broke down and I couldn't even afford to take it to the
garage to have it checked out. So I went to the dealership and bought a
new truck I really couldn't afford. I had transportation, however, and
I only had to look forward to a monthly bill for the following five
years. I would have much rather had the old one fixed.
I probably won't replace my '98 Sable until (a) I can pay cash for a new
one, or (b) it starts looking like an '87 Taurus in comparison to the
2004 models. I used to have an '87 Taurus in 1997 and I loved it, looks
and all. Now they look horridly antiquated in my eyes. Based on that
projection, perhaps I'll really like the looks of my Sable until 2014.
Now wouldn't that be amazing! If, once I get this Sable paid off, I
continue making car payments to myself, I should have enough to pay cash
for a new Sable in, say, six and a half years. I still have a year and
a half more to pay on my current Sable as I financed it for 24 months.
And if, along the path to saving to pay cash for a brand new car, I
happen to run into a major problem with the '98 Sable, at least I'll
have a substantial amount of cash to certainly pay for any repairs.
It'd be a setback to getting something new, but I'll still be rolling.
Or, still, at that point, I'd have enough cash, maybe $10,000, to allow
me to put a huge down payment on a new car. But I think my Sable will
have to get into pretty bad shape before I'll want to buy a new one.
And I won't get a new Sable until they put the gear stick back on the
steering column and lose the center console.
On the issue of repairing the cracked case, the best idea would be to get
the opinions of both a reputable TIG welder and machine shop. The welder
can tell you if the repair is feasible by metallurgical factors, and the
machinist should be able to discern if any registered bushing fits, etc., present
in the repaired area of the case can be restored. It should be noted,
however, that welding on aluminum will pretty much destroy any hardening
procedure performed on the case during manufacture. I am not familiar
with the guts of the AXOD (or whatever is in those cars in '97) and
cannot guess how much of an effect this would have, but would personally
be very leery. The transmission would need to be completely torn down
and cleaned thoroughly to prepare for welding, so add up the R/R costs,
overhauling, welding and machine work, and it may end up being more
expensive than a total replacement. Also, it is common practice
(actually recommended by GM for TH350 family trannies) to repair case
porosity with epoxy; this should never be considered an option to repair
a crack, however, particularly in the differential area.
Anyone else have opinions?

You don't say how bad the crack is. Is the trans still functioning
except it has a leak? You may think I'm crazy but if it just a leak
there may be an easier way. A couple years ago I watched my son in-law
repair a leaking gas tank with a product he got from a company call New
Pig. If I hadn't seen it I wouldn't have believed it. Sold the car a
year and a half later and it was still holding up fine.
I found the website for Pig. There's an 800 number. Might be worth a
try. Good luck.
Cases just do not crack, the reason it cracked is most likely a problem inside
the transmission ( most of the time the planetary failed ). If it is really
cracked, the transmission is now a paper weight, have it replaced. It is not
that common now, but in the late 80's and very early 90's it did happen.
