A general problem that can develope with modern computer controlled
automatic transmissions is a bad electrical ground. Because of the
different metals being bolted together (cask iron block, aluminum
transmission, steel bolts, etc. electrolysis at the interface of the
different metals can occur which won't weaken the physical connection, may
not be visible, but can cause poor conductivity. Because the transmission
needs a good electrical ground for the computer to function properly it may
be as simple as creating a new ground. Mileage isn't much of a
consideration in the developement of this condition (unless you drive in a
corrosive environment), but 13 years is old enough for it to happen. Before
spending any money I would run a wire from a good ground point on the
transmission to a good ground point on the engine or chassis - you don't
have anything to lose.
