Its something in your transmission. Like a temperature sensor, maybe not, but its def in the trans. When a car gets to a certain speed something is to click over in the tranny to allow for more efficient driving. Something inside yours isnt doing that automatically. Have a highly trusted shop take a look at it.
Also the on off deal is to get computer codes directly from your computer. Via the service engine light.
