While traveling home down 95, I decided to get on the throttle alittle bit. I ran over 100 up to 140. I came up ro an accident and slowed down. I noticed the car felt rough slowing down.After I got passed the accident, when I started to accelerate, the trans slipped. I drove to my exit, but the car ran at high rpm and wouldn't shift. When I started off this mourning, the car slipped and the check engine light came on. I checked with OBDll which showed trans code 700. Turned light off and drove on. Light doesn't. come back on, but car won't shift from 2nd to 3rd. Can you give me some insight or direction. Thanks.
