As for design changes- other folks here have enumerated
the hardware and software changes over the years. But
most of them really weren't necessary- my first-flight
(1993) unmodified 42LE went 150,000 miles because I
a) kept the right fluid in it, and b) didn't let anyone
rebuild it when a $30 sensor failed (the actual cause
of 99% of the the alleged "failures" of the 41TE/42LE family).

Why do other transmissions seem to work more reliably than that
Chrysler even when the fluid in them isn't changed often -- or at all?
