Transmission does shift a bit harsh copared to my '98 T&C.
When I come to a stop my van hesitates to downshift and when I go to accelerate it hesitates to shift up in gear. My check engine light recently came on so I had it diagnosed and what came up was the shifter selenoid...at least thats covered under my warranty
