take it to an accredited auto transmission specialist shop for an exact diagnosis of the fault
I seriously doubt that you have a transmission box mechanical fault so get a second opinion if a replacement transmission is suggested

Possible causes of OBD code P0780
- Low transmission fluid level - Dirty transmission fluid - Faulty shifting solenoid valve - Shifting solenoid valve harness or connectors - Shifting solenoid valve circuit is open or shorted The Error code is generally activated on detection of the following conditions: The P0780 codes is detected when no rotation change occurs between input (turbine revolution sensor) and output (revolution sensor) and shifting time is long or when shifting ends immediately or when engine revs up unusually during shifting.So check out these points and see if any are all help keep me posted

If it is locked in park, it could be the brake switch or the shift lock solenoid. You may be able to shift out of park before you turn the key switch to the on position.
