From the fault codes that you are getting you may have a transmission wiring harness problem Check: wires corroded in half at connector in left front fender well behind splash guard. Or under the battery. You may also have internal transmission problems like the solenoid pack failure. I also wouldn't rule out a faulty TCM (Transmission Control Module)
