GENERALLY the tranny problems (in the last 15 years) can be almost
eliminated if the fluid is changed often enough with the right fluid.
Once every 15000 miles, or maximum 2 years, is about right.

Of all the cars I've owned, only one ever needed tranny work. It was the
only one I ever changed the fluid in too. Never again. No way a trans
should need a fluid change in 15000 miles.

If you are driving a Chrysler and you doi NOT change the fluid, it's
your funeral. Leaving the old fluid until you have a problem
GUARANTEES it will fail just after you change the fluid - as does
using the wrong fluid.
250,000 miles on a Chrysler automatic is NOT out of reach, or even out
of the ordinary, if it is "properly" serviced.

From what I understand the reason is because chrysler intentionally
choose to use undersize transmissions (one that one be used on a smaller
series is fitted on a larger series) so they run much hotter and destroy
the fluid much faster. The only hope of keeping them alive is to do very
frequent fluid changes.
