While the Check Engine light is always on - What causes a 98 Caravan 3.3L automatic to sometimes stay in 1st gear and not shift into 2nd until the engine is shut off then started before it works fine?
On some models, like my 1997, there are computer updates that the dealer must do. I'm told (by the local dealer) that these updates often correct some problems and make the vehicle operate more efficiently. If you're lucky, this could solve the problem. If not?
