Code p 1778 refers to CVT step motor--mechanical malfunction===causes ---step motor
the CVT is a constant velocity transmission that has no gear ratios as such but uses a special belt between two pulleys that change flange widths in unison so that as the road speed increases one pulley gets smaller and the other larger
the step motor controls the pulley adjustment
Take it to a service dealer or an accredited specialist transmission shop with experience on that transmission
