I did not make myself very clear. The downshifting I was referring to
was not to maintain speed when going uphill (they all do that). What I
meant was downshifting to maintain the set speed when going downhill...
when simply throttling back is insufficient. I know of no other
vehicles other than Chrysler products that will do that. It seems very
strange since the inclusion of such a feature is nothing but a small
amount of firmware.
