I have a Ford five hundred When the wrench light is off The transmission shifts

Hello, the wrench light indicates a possible problem with the throttle control or the transmission operation. Diagnostic testing must be performed to determine what the cause and source of the problem is. Testing with a diagnostic tool capable of retrieving diagnostic trouble codes, as well as monitoring component operation is needed.
