A month ago the check engine light came on with a P700 code. I was told it could be the speed sensors. Then it was fine, and yesterday it seemed like it was taking a while to shift starting out and the autostick wouldn't work. Then today it was fine until about a hour ago. It seemed like it wouldn't go, then I pulled over, turned it off and then on, and I got home, but the engine light is on. What does that sound like? I hope not a new transmission. Its hard to trust these mechanics, they will just say you need a new transmission.
