i have a 98 caravan. now first started driving it today it was fine. then about 10 miles or so it would not upshift from the stop sign. just stayed in first. so i tried shifting it manually. it started in first then when i put it in 2 it shifted, then in drive nothing. so i tried in drive again and it just stayed in first. any ideas? levels seem fine and everything. please give me any ideas. i use this dailey for work. thanks again.
