They do have pressure control solenoid and valve body problems. Dtc's p1811 and P0742
can "usually" be repaired with a valve body, spacer plate, P.C. solenoid, and a TCC PWM solenoid. As far as it not moving at all and making a whining noise points toward a pump or a torque converter stator. If it whines for a few seconds afer the engine is off the only thing that could be spinning is the stator. Everthing else will stop rotating with the engine off. A line pressure test will tell alot also.
