Sounds like you may have limped the tranny. Read about it here:

Is your SES light on?

check engine light is on, how do i unlimp it? tried turning off and restarting it

You may have to clear the codes. If you don't have a scanner or know somebody that does, you will have to take it to the dealership.

Edit: Also try turning the Edge down.
