What does P0780 Shift Malfunction mean, do I need a new transmission? on 2002 Honda Accord

What does P0780 Shift Malfunction mean, do I need a new transmission? Check engine light came on 5 months ago, sometimes my car shift gears hard then continue shifting smooth. This happens more frequent now. CODE P0780 Shift Malfunction

Asked by for the 2002 Honda Accord
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.
Here's a directory list for you:
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.
