Speed sensor is not in the Transmission, it is in the T Case, back side near the top. If it is not screwed in all the way, or has a bad connection, you will have the problems you describe.

Thank You Sir, the sensor was tight so I took the wire out and cleaned it and put connection grease on it so I hope that takes care of it. Thanks Again!!
