The light is indicating that the transmission controller has detected a malfunction, the hard shifting is probably bacause the controller is running the trans in fail-safe mode to avoid damage to the unit. When the light's on, there are data and trouble codes stored in the controller which can be accessed by a technician with a scanner. Find a transmission shop or a Ford specialist.
