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

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?
