What P0767 usually means
P0767 is the stuck-on branch of the D-side shift-solenoid story. That matters because stuck-on faults do not feel the same as a dead or missing solenoid. The transmission may overlap shifts, hold the wrong gear too long, or behave like one hydraulic command never lets go after the module has already moved on. In real diagnosis the fault can live in a shorted circuit, a mechanically jammed solenoid, or a valve-body path that keeps pressure applied after the command should have released. That makes P0767 useful because it narrows the symptom pattern instead of treating every harsh-shift complaint as the same.
