    P0780 indicates a shift solenoid malfunction. If so, you probably wouldn't need a complete transmission overhaul, just some valve body work to replace the solenoid(s). P0780 doesn't specify which solenoid so some diagnosis would be required.

    Does P0700 Mean I need a new Transmission or is this code for information only? I had a Transmission scan done for P0780 code and was advised by AAMCO yes I have a code P0780 but I have a new code of P0700 and they recommended I need a new transmission $1900-$2400 to repair, but my car shifts smooth at times but sometimes in 2nd or 3rd it shifts hard. Can someone please expalin what does P0700 mean?
