The P0780 code you are getting is a shift control fault. The first thing you should do is to change the transmission fluid. You will want to inspect the old fluid for any metal debris or other signs of contamination. After you have changed the fluid, clear the code and drive the vehicle. Hopefully this solve your issue as the fresh fluid may free up a sticking shift valve. Try that and please let me know how it goes.
