1997 Dodge Grand Caravan Transmission Problem?

the shift solenoids are all together known as a solenoid assembly did they change it when they did the rebuild? most shops will did a shop do this? then maybe still under warranty? also problem with one of the speed sensors you have a input and ouput also could be a pcm problem will have to take it to trans shop and let them scan it will be able to narrow it down and you can go from there
