HelloCustomer code p0775 is indicating that your vehicle has a mechanical failure of a shift solenoid internal to the transmission. Certain tests must first be completed to confirm that it is infact a solenoid and not electrical wiring going to the solenoid assy. I have attached the pinpoint test that would be followed at the dealer to correctly diagnose this code, and if it is infact the solenoid pack assy, it could run approx. $400 for the part depending on where you live, 65 for new fluid, and approx three and a half hours labor at your local shops labor rate.
