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: http://repairpal.com/directory?address=30213&car_brand_names=Honda
