As far as I know it's the same one the Windstar used. just look it up on the
web. Some last a long time, many don't.
AX4N was a bit better than the earlier AX4S,AXOD etc were not very good in
Some may have that opinion but it always has to do with proper maintenance.
If there were actually a design defect in any product, as the phrase "prone
to fail" indicates then they would all be failing and that was never the
We had the same situation with failing gaskets in the 3.8 engine. Because
some fleet vehicles accumulate mileage more quickly than private vehicles,
and we did the proper maintenance, we discovered failing gasket long before
the engine was damaged by diluted oil, and changed the gasket. Fleets
were also the first to realize that the replacement gasket was not
correcting the problem.
It was a result of what fleets first discovered that led Ford to begin
litigation with the gasket manufacturers, who were blaming owner negligence
as the cause. Similar to Toyotas contention that owner negligence was the
cause their "oil sludge" problem, when in fact both the gasket problem and
the sludge problem we manufacturing problems by the gasket manufacturers and
with Toyota new head design that led to oil "coking" around the valves. I
was deposed by Ford legal council as a witness for Ford in the pending
The result of Fords ligation was an out of court settlement that helped all
manufacturers, using gaskets with asbestos replacement materials that were
not up to the job, to agree to pay 80% of the cost of fixing engines.
However by then reputations were damaged
In Toyotas case the result was an extend warranty on those engines that were
effected by their sludge problem, after we produced records that verified
that sludge was occurring in engines that fleets serviced, at the propter
times, using the proper filter and oil. Toyota dealers, using the proper
filter and oil at the propter times, were starting to see the sludge in
engines, as well.
The AX4N in my 2001 Sable was given "proper maintenance" at the L-M
dealership, at earlier service intervals than specified by Ford. This was
done specifically because I knew of the problems with the AX4N and its
predecessors. It failed anyway at around 97,000 miles - failing with
practically no warning. We had just enough time to get the vehicle off the
interstate before it would no longer move the vehicle.
I agree with Steve R's comment - some do, some don't. My '96 Sable did not
have a total failure up to the 127,000 miles I owned it. My 2005 Sable has
had no failures as of 58,000 miles.
Certainly some can still fail, I never said none will failed. What I said
was that tranny was not prone to fail, as was suggested, big difference
Even properly maintained vehicles can still have a failure. If anything is
prone to fail they all will fail and that was never the case.
As I said previously the fleet service company, I formerly owned, serviced
most brands of vehicles domestic and foreign for nearly 100 different
government and corporate fleets in six eastern states.
Over the years many thousands of them were Taurus', with that tranny and the
failure rate was no greater then the average number of failure rates for
transmissions, in general.
you were going to keep and drive the car as is a salvage title would
make sense. However, a 93 Taurus has very little value on the resale
market - I'd take what they are offering and put that money directly
towards the purchace of your "upgrade" = forget all the hassle and
uncertainty around the value of the "salvage" car.
Bottom lines of your VIN decal.... there is a listing "TR".... beneath that
a single letter.... If it it a <L> then you have the AX4S trans. If the
letter is a <X> then you have the AX4N trans...
Now... the S stands for synchronous and the N stands for non-synchronous...
we'll leave it at that for now....
Additionally, the AX4S is the old AXOD transmission renamed... and the
letters AXOD will be stamped in the main control cover. The AX4N has, at
some time in the past, been re-identified as the 4F50N...

Below the TR it has an X letter, so it's the "AX4N" non synchronnous
Is there anything I can learn from that, now that I know which tranny
Is the tranny known as a work horse or a lot of problems?
I appreciate your help.
